Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.
Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.
It makes 7.72Mwh per year, worth $1000. Tight valley, tons of snow.
We put that on the loan for 8 years, then get $1000 per year free money for 20 years or so. Biggest no brainer of all time.
Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)
Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.
> Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.
It would be worth including control of the people who vote for the politicians by direct investment such as when the oil producing Saudis bought the second largest stake in NewCorps which controls FoxNews controlling the content that influences voters. And, less than ethical control using bots on social media by Russia.
A lot of what influences "solar prices in the US" is controlled by foreign oil producing countries like Saudi Arabia and Russia controlling content and media consumed by American voters.
Here in California, they drastically cut back on the price that you get for solar powered electricity from homeowners. It used to be around $0.30/kWh at any time of day and now it's can drop to $0.00-$0.05/kWh during the day when the state is sunny. If you can afford to have a battery installed, the rates are far better as you can either run off the battery when rates are the highest in the evening, or you can export it back to the grid when prices are much higher.
The price is signaling that additional solar power production during the day isn't very useful; and additonal solar power production in the early evening when demand is high and the sun isn't shining and you need a battery system to have already been accumulating energy during the day is useful, albeit more expensive and complicated to build and run.
With falling battery prices this should be an addressable problem. Soak up the locally generated excess energy and sell it later in the day when the need is there. Electrical arbitrage seems like a win/win solution for the utilities their customers.
The first round of people paid way more for their solar panels though, and those higher prices helped bootstrap the industry. Should people who paid much less for panels get the same reward? I'm having trouble getting outraged about this, it seems to be incentives working exactly as they should.
I agree, and maybe my "ladder pull" comment comes off as too negative. Most early solar buyers were either in it for environmental reasons or for a modest return on investment. I don't think many were expecting a windfall.
Residential solar is completely counter-productive right now in california. Just take a look at the CAISO price maps during the day when the sun is shining. There's so much power they are paying people to consume it. It's a negative force for grid stability. Getting paid for making the grid less stable is ridiculous. Until there is widespread battery storage or massively improved transmission and distribution systems grid-tied residential solar is a solution in search of a problem.
The list of the oil producers listed and omitted on a given forum in these contexts is always interesting. On HN it is often SA or Russia, and almost never Qatar or Iran.
I agree wholeheartedly, and the technocrats are complicit with the GOP here.
It's funny how “free markets” keep producing the most expensive solar prices in the developed world. Don't get me started on Healthcare (I just moved back to the U.S. a couple years ago after 18 years in Canada, what a cluster*ck).
Oil and gas buy politicians, foreign oil money buys media influence, and social-media bots keep voters angry at the wrong targets.
Saudi capital helps shape the messaging, Russia helps amplify the noise, and Americans get stuck paying more for clean energy while being told it’s patriotic.
If even a Democratically-led California is doing this, how can you point fingers at just the GOP? It's endemic to the system, and not restricted to just one party.
Republicans are always trying to increase and protect oil subsidizes, cheer "drill baby drill", and have social media tools peddling their bs who are funded by foreign influence campaigns. The Democats may not be perfect, but they are much more likely to cut oil subsidies or at least subsidize solar and other renewables to balance. This is especially true as the next generation takes over by primarying the tepid fossils currently in office. Meanwhile, dear leader Dumpty likes to suggest windmills cause cancer because he doesn't like what they look like on the horizon of his golf dumps. Saying this is a "both sides" problem is laughable.
The US doesn't have a free market in either health care or electricity generation. An actual free market in solar power would probably result in more or less what we are seeing with the actual highly regulated market in electricity, namely extremely cheap prices for additonal solar energy in the middle of the day when the sun is shining, higher prices for additonal solar energy in the evening when demand is high and the sun has gone down, and some fixed cost to pay for physical electric grid infrastructure that needs maintenance regardless of whether it is being used at any particular moment.
Oil and gas don't buy polticians more than any other industry does, but voters do get particularly angry at politicians when the price they pay for energy suddenly spikes.
Figure out what you can do without a permit or inspections in your jurisdiction.
For example, in my jurisdiction it's: < 5 square meters of panels on your roof, <60V DC, AC on homeowner side of panel (as long as electrical work done by homeowner).
That's not a lot, but my primary purpose is as a generator replacement -- keep my fridge powered during a summer power outage or my furnace fan powered during a winter one. The other 364 days of the year it just slowly pays for itself.
Panels, battery, wiring and paying a roofer to install the flashings for the mounts all cost under $3000. A single one of the required inspections would have cost about that much.
>Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.
>Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.
This very well may be true, but taken at face value Canada seems to be paying you around $7k to install solar panels on your roof (that's 8k interest free loan is losing out to inflation + any interest it would have earned).
Definitely a great deal if you own a home, if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.
> Definitely a great deal if you own a home, if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.
What kind of selfish point of view is this? Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year? Seems like a no brainer deal if you like "the outside" and you want it to still be there.
I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me. But I also feel the same about elder care, health care and a bunch of other things, do you feel the same for those things too, or this is specifically about solar or owning vs renting?
> What kind of selfish point of view is this? Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year?
Only if those who make the same or more than me are paying that same tax. After their subsidies of course.
Rich folks getting even richer off the backs of poor folks is bad. Even if it's dressed up as good for the environment or whatever justification you want to come up with.
As a homeowner, I would not take these subsidies as I find them to be immoral. Doesn't mean I won't be installing solar, but I'm doing it for far different reasons than saving money.
By your logic, shouldn't homeowners stop being selfish and just pay for these things themselves in order to make the world a better place? Why do they need renters, other taxpayers, and other ratepayers to subsidize them?
>I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me.

There's an alternative, and almost certainly cheaper per watt with cost of scale, where your tax dollars go to a new solar farm instead, something everyone could take advantage of.
It's not zero sum but different physical layouts of energy generation do have different captial and operating costs. Rooftop solar power goes into the grid but maybe not at the most ideal time and scale for the grid operators, which justifiably affects what price they're willing to pay for that power, which justifiably affects the ROI for homeowners with rooftop solar panels.
Rooftop solar has lower distribution costs. A solar farm needs new transmission and upgraded capacity distribution lines to get the power from far away to the users. Generating solar right next to your neighbors lets them access your surplus cheap power with existing slack capacity in the distribution lines. Our current monopoly utilities don’t have a mechanism to recognize that value created, and they would prefer to keep building more infrastructure as that’s what increases profits for them.
The solar farm produces more energy per dollar spent. Rooftop solar is expensive. It produces comparatively fewer kw to amortize the fixed costs over - permitting, getting up on the roof etc.
If a country has abundant land and expensive labor, the money is probably best spent improving grid transmission capacity and otherwise getting the f- out of the way of utility-scale renewables. Places like Pakistan, which is going through a rooftop solar boom, are arguably the opposite - scarce land in the cities, but cheap labor to get up on roofs.
Happy to hear any analyses to the contrary and update my knowledge accordingly.
OK, so rooftop solar is a higher <currency-unit>/kW solar farm. That's one argument against it.
On the other hand, it is also distributed which from some perspectives is a benefit, and is also do-able with very little planning and grid extension. So that's one argument for it.
How things come out on balance depends a bit on what you value and how you imagine the future.
The generation is distributed. That only benefits the people who have panels on their rooftops. If we want them to share the excess with others during a power outage it requires further grid investment.
I think homeowners should install solar panels and batteries where it makes economic sense. If there's money left over after funding utility-scale solar then it should be used for EV incentives and/or funding electrified mass transit. The whole point is to electrify everything rapidly and reduce carbon emissions.
You absolutely do not want them sharing the excess with neighbors during a power outage, this is how you get dead linemen.
Solar panel grid tied inverters generally will refuse to function if there's no external power coming in.
The benefit from the distributed generation means that if your local area has large loads added you don't necessarily need to upgrade the HVDC lines from the power plant to accommodate.
This is not as big a problem as it sounds - you cannot provides enough power for you neighbors and so your breakers (fuses) will cut power long before the lineman gets there.
though linemen are trained that they are working on a live line unless they have personally shorted it out. There are many other ways a seemingly dead line can be live so they don't take a chance.
> This is not as big a problem as it sounds - you cannot provides enough power for you neighbors and so your breakers (fuses) will cut power long before the lineman gets there.
The load side (your neighbors) cannot pull more power than is being generated. My 7kW array can generate 7kW and no more. No breakers will trip in a hypothetical scenario where my inverter fails to shut down during an outage, and my neighbors are trying to drawing 10kW.
Because you get far higher ROI for the large-scale installations. In case you weren't familiar, Canada has a lot of other things which need the money than paying 5x per watt to subsidize panels on your roof instead of on the ground.
> Because you get far higher ROI for the large-scale installations.
Right, but as always, ROI is hardly the most important thing in life, there is more considerations than just "makes more money". For example, as someone affected by a day long country-wide electricity outage where essentially the entire country was without electricity and internet for ~14 hours or something, decentralizing energy across the country seems much more important, than optimizing for the highest ROI.
But again, this is highly contextual and depends, I'm not as sure as you that there are absolute answers to these things.
Grid-tied solar is fragile. If the grid is not nearly-perfect, it won't generate. It will not help society as a whole.
If you personally have battery backup, that helps you personally and you should pay for it, just like you might pay extra to turn up the heat while I keep it lower to save money.
It's not as if homes outside of cities have their own diesel generators to power their house.
(Since I'm guessing from this line of comments you'll point out the less than 1% of people who actually do do this, maybe it's better to focus only the 99% here).
> It's not as if homes outside of cities have their own diesel generators to power their house.
Yeah, no true, I don't understand the point/argument though?
More people relying on renewables == long term better for everyone on the planet
That includes moving people outside of cities to renewables energy sources, is your point that this isn't so important because they're a small piece of the population usually?
>I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me.
That's because you're rich like most people on HN.
Environmental protection is a luxury good. This has been proven time and time again.
A great reason to prioritize growth and wealth creation. Poor countries don't make those tradeoffs, they're worried about survival not what percentage of their energy usage is renewable.
Solar hardware is so affordable now that it's booming even in poorer countries. The most remarkable recent example is Pakistan, which has seen explosive growth of rooftop solar power, most of it receiving no government subsidies:
Pakistan has imported almost 45 gigawatts worth of solar panels over the last five or six years, which is equal to the total capacity of its electricity grid. Almost 34 gigawatts have come in only in the last couple of years.
It’s a very bottom-up revolution. This is not government deciding this is the route to take. And it’s not being driven by climate concerns, it’s all about the economics. Renewables are out-competing the traditional sources of energy.
Great job of indirectly implying that there must be a tradeoff. Funny thing though: those poor countries? They're not building nuclear, or oil fired, or coal fired, or natural gas plants. They're installing solar. Not necessarily because they care about what percentage of their energy usage is renewable, but because there is no tradeoff.
Further, environmental protection is not a luxury good, it's a long term investment. Ask me more in another 30-50 years when the larger impacts of climate change are happening. Or ask someone else about how much we've spent on superfund cleanup sites.
Everything has a tradeoff. That's a foundational truth of economics.
Environmental protection is a luxury good in economic terms. The Environmental Kuznets Curve is compelling to me. It's extremely difficult to assess the ROI on long term investments, particularly when your country has unstable rule of law or conflict.
I'm pro-solar, it's amazing technology that empowers individuals and communities. I just don't agree that everything I love I must force other people to pay for.
Environmental protection may be a long-term investment, but reducing CO2 emission is probably not. The results are too diffuse and you're at the mercy of other countries' energy policy. If you're a small country, you can invest in CO2 reduction all you want, but what actually happens will be up to the US, China, and India.
Environmental protection IS about survival for poor countries. YOU can afford to not care and burn gas because you won't have your life completely and permanently destroyed by global warming. Poor people don't have that luxury.
Rethink your position because it's completely upside down
> That's because you're rich like most people on HN.
Probably, but I also haven't been rich all my life, I've also been broke and borderline homeless, and my point of view of paying taxes so others get helped, hasn't changed since then. In fact, probably the reason my perspective is what it is, is because money like that has helped me when I was poor, and I'd like to ensure we continue doing that for others.
And I agree, poor countries can't afford to think about "luxury problems" like the pollution in the world, but since we're talking about people living in such countries where we can afford about these problems, lets do that, so the ones who can't, don't have to. Eventually they'll catch up, and maybe at that point we can make it really easy for them to transition to something else?
> A great reason to prioritize growth and wealth creation. Poor countries don't make those tradeoffs, they're worried about survival not what percentage of their energy usage is renewable.
Tell that to places like Pakistan where solar is allowing people to have cheaper electricity without connecting to the grid
That's exactly my point. They're making decisions based on their economic reality not sacrificing for environmental principles like the above commenter.
Solar is great. It can stand on its own without subsidies.
Keep in mind the standard of living. If you’re in a country that experiences routine long power outages, having a solar panel that you can use to charge your phone during the day is pretty great. Having to get ahold of and burn diesel fuel is not so great. Doesn’t produce at night? Doesn’t matter much, it’s better than nothing.
There is line that connects gov't subsidies in wealthy countries for the last 50 years funding private R&D to poorer countries being able to afford it. Arguably the poorer countries don't get to make the "decisions based on economic reality" in favor of solar without the subsidies in wealthy countries happening first. There is also an argument to be made that the R&D isn't finished and it still makes sense to subsidize it to drive the cost down further.
> There is also an argument to be made that the R&D isn't finished and it still makes sense to subsidize it to drive the cost down further.
Maybe there is an argument to be made, but it sounds like a very poor one if poor countries are now putting up solar panels because it's the cheapest form of energy production. Sounds like subsidizing the same panels going up on houses is a bit silly now that the costs have shifted so much.
The argument can probably be made for direct subsidies of R&D for bleeding edge solar tech, and perhaps even battery installations to get volume up. Or maybe even subsidizing local production vs. buying everything from China.
The arguments for wealthy countries to subsidize their wealthiest citizens to install solar for personal gain seems rather weak at this point in the game. It certainly made sense 20 years ago, but in most areas where it makes economic sense to begin with solar penetration has hit a tipping point.
> But at a national level the data is compelling. I'm convinced by the Environmental Kuznets Curve.
Which data do you find compelling?
For people who don't know the Environmental Kuznets Curve is basically the hypothesis that as economies grow past a certain they naturally start to cause less environmental damage.
As far as I can tell the main empirical evidence in favour of this is the fact that some western countries have managed to maintain economic growth whilst making reductions to their carbon emissions. This has, of course, partially been driven by offshoring especially polluting industries, but also as a result of technological developments like renewable energy, and BEVs.
On the other hand, taking a global sample it's still rather clear that there's a strong correlation between wealth and carbon emissions, both at the individual scale and at the level of countries.
It's also clear that a lot of the gains that have been made in, say, Europe have been low-hanging fruit that won't be easy to repeat. For example migrating off coal power has a huge impact, but going from there to a fully clean grid is a larger challenge.
We also know that there are a bunch of behaviours that come with wealth which have a disproportionately negative effect on the environment. For example, rich people (globally) consume more meat, and take more flights. Those are both problems without clear solutions.
(FWIW I agree that solar power is somewhat regressive, but just for the normal "Vimes Boots Theory" reasons that anyone who is able to install solar will save money in the medium term. That requires the capital for the equipment — which is rapidly getting cheaper — but also the ability to own land or a house to install the equipment on. The latter favours the already well off. There are similar problems with electric cars having higher upfront costs but lower running costs. The correct solution is not to discourage people from using things, but to take the cost of being poor into account in other areas of public policy).
Agreed. But there are poor people in Canada, and forcing them to pay more money (and slightly lowering their own quality of life) so that wealthier Canadians can install solar panels is, at least, a debatable policy.
We have progressive tax rates in Canada which should offset this to some extent.
Also, you keep ignoring that the environment is a public good. Poor people in Canada will also be disproportionately impacted by bigger temperature extremes (heat waves, extreme cold), worse air quality, etc.)
Does Canada not have progressive taxation? How do poor people pay more than rich people?
To be clear, I don't think rooftop solar subsidies are the best use of government money either. Governments should subsidize utility-scale solar, EVs, efficient buildings, and mass transit. They should focus on cheaper and more efficient permitting, and better grids.
> Does Canada not have progressive taxation? How do poor people pay more than rich people?
It’s not that they’re paying more than rich people. It’s that even with progressive taxation, tax(everything the government currently spends money on) < tax(current spending + solar subsidies). That is to say… giving solar subsidies to rich people causes the tax paid by everyone to increase. Those making more money pay a larger fraction of the increase because of progressive taxation but everyone who is paying taxes pays incrementally more when the government spends more money.
Canada should invest in Nuclear. Solar is far less efficient in Canada than somewhere like California - whether rooftop or utility-scale. The short winter days, low angle of incidence, and snow means that panels are basically non-operative for 3-4 months a year. This is a huge problem if you also want people to switch to efficient electric-powered heating in the form of heat pumps.
Great, if the break ground today the first nuke will be online in absolute minimum 10 years (likely 20) and cost absolute minimum of $15 billion (likely closer to $30 billion)
Do you want to guess how cheap solar will be in 10-20 years, and how much power we could generate in the mean time.
The efficiency of solar does not matter in 2026. Panels are so cheap that just you don't have to think about it if you have abundant land. If solar is 4x less productive in the winter you just build 4x as many panels. Panels have to be angled more vertical the further north you go so the snow will just slide off. They are not "non-operative 3-4 months a year" - this is just Big Oil FUD.
the only reason environmental protection could conceivably be considered a luxury (and not a necessity) is because certain sectors of the capital class refuse to convert their means of production away from generating waste and pollution. that's it. time and time again we see direct action by Chevron, BP, Shell, Exxon, ARAMCO et al to stifle change, refuse scientific evidence of the nature of their pollution, and attack anyone who comes anywhere near impacting their bottom line. look at Steven Donzinger if you need proof of this.
this is not a matter of some fictional invisible hand. these are decisions made by real people who do not care about you, society, the health of the environment or the people who inhabit it. stop carrying their water.
As a renter, I'm
moderately more in favor of utility-scale solar subsidies rather than subsidizing private solar. It seems like another way to make the arrangement more "fair" is to subsidize private solar, but credit the grid up to the original grant's amount. In other words, in the GP's case, they would only get $1000/year in free money for 15 years instead of 20.
(This is very low on my list of things that I care about, to be clear.)
Maybe I'd prefer to spend the same public money on building nuclear power plants, or gigantic solar panel arrays in the desert, rather than subsidizing individual roof-owners being able to save money on their electricity bill and not mine.
>Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year?
If everyone gets the benefit it's either A) exactly the same cost but with additional government program or B) some form of wealth distribution and not necessarily in a direction you favor
Also large solar installations are significantly more cost efficient.
Mind you I am IN FAVOR of subsidized residential solar, but let's not pretend government money is free.
> There is nothing more unjust than forcing someone to buy something they do not want simply because you think it would be good for them.
Who said that? Taxes are what you pay to be a member of the society you live, and also to help those less fortunate, like your neighbors. You can skip paying those, if you stop living in society, many done that before, and it is still possible.You can't possibly see taxes as "forcing someone to buy something they do not want" right? Two completely different things.
And yes, this is all my opinion, like most comments on HN.
It certainly is possible, people do it all the time, in various countries. Most of the time we call them "homeless", but also there are people who literally set up camp in the forest then stay there, it isn't unheard of.
The book "The Stranger in the Woods" is one such case, about a man who lived in the woods for 27 years by himself.
That said, it isn't easy, and it's harder in some countries than others, but I'd still say it's possible in many countries today, YMMV.
Not OP, but it wasn't presented as a fact. Literally used the word Seams.
> There is nothing more unjust than forcing someone to buy something they do not want simply because you think it would be good for them
Seatbelts? Circuit breakers? Literally any safety equipment. You're required to have them because it's not just good for you, but expensive to society if hospital beds are low or there's not enough firetrucks to go around.
Similarly, if you're polluting more than you have to be due to the source of your electricity, that's bad for everyone. I also rent, but I still understand that it's to the public's benefit that home owners (a class that is already above me in assets and wealth) be given motivation to consume cleaner energy if I don't want to have the climate get even worse. It's the same thing, just the effects feel less direct. That doesn't make them any less valid.
> As a non car owner are you annoyed everyone gets subsidized roads?
Yes, and people should be annoyed by this given the underfunding, poor urban planning, and outright hostility by many local governments against anything that dares encroach on the sanctity of car culture.
"Car culture" and "public roads" are not the same thing.
I'm a militant cyclist and I'm extremely unhappy with the state of urban planning in the world. But... Roads are a really good thing and I'm glad my government builds them.
I just wish they'd built them a bit differently, at least in the city.
So you do not use busses,taxi or road travel? do you fly all the time?
Do you have stuff delivered by truck/cars or only by air?
What about shopping? do you think the items you buy or the things needed to make those items use roads ? In a perfect extremist capitalist word there would be a road tax included in the products and services so you would still pay the text for the roads.
Yes, the costs should be apportioned to those who are making them. If the bus causes the most road damage, then it should be charged. Then it'll make financial sense to invest in rail. Financial incentives are how capitalism works and the purpose of governments under capitalism is to apply externalities to the source causing them.
1. As soon as the roads are all paying best-possible-use property tax for the space they take up and it's completely paid by automobiles, in addition to all maintenance, we should try to proportionally assign dedicated bicycle infrastructure costs toward bicycle users, now and anticipated.
It'd be interesting to try charging vehicles relative to the road damage they do as it's proportional to around the fourth power of weight. It would likely change the nature of logistics as it could mean that large trucks would be more expensive that using two or three smaller trucks. Similarly, buses would benefit from being smaller and lighter.
No, in a perfect world, there would be a use tax, and those doing the delivery would pay the cost, and then pass that cost on to you. You might have meant it that way, but it sounded more like a gov. imposed tax based on the price of goods or something.
> So you do not use busses,taxi or road travel? do you fly all the time? Do you have stuff delivered by truck/cars or only by air?

"Yet you participate in society, curious!"
> In a perfect extremist capitalist word there would be a road tax included
There's nothing capitalist about that. Driving around and polluting the environment is currently done for free. That should be taxed. Highways and streets are by and large (in NA) used as a publicly subsidized private good at the expense of everyone else. Subsidized to the detriment of all because it pulls funding away from public transit that would move more people, prioritizing convenience of drivers over the safety of everyone else (to say nothing of it creating dead spaces with nothing but parking as far as the eye can see).
Public transport uses the roads too.
In my country Romania there are road taxes included in the fuel prices and there are vehicle tax that is proportionalw itht eh engine size and vehicle age and how mych it pollutes. So people that drive more use more fuel and pay more tax. If you use your bike then you will not pay that taxes, now what should we tax for the bike lanes ? And how should we convert he fuel road tax for electric cars ?
Why are you acting like subsidizing a homeowners free power is like any of these?
If I instead phrase it as "I'd rather subsidize someone's health care than pay for your free electricity", would that help you understand that there tends to be a priority system when spending tax dollars?
You don't have infinite tax dollars to spend after all.
> Are you annoyed corn farmers get subsidies for growing corn?
Yes we should immediately end these subsidies.
> It feels like the US can’t have nice things because people are hell bent on others not having nice things.
The US as a whole has lots of nice things. And sometimes the things the US has are not as nice as they could be because an unwise subsidy is paying for something inferior, and a small group of people who financially benefit from the subsidy advocate politically against changing it.
If you're a renter/condo then you're probably getting excess solar generation delivered to you from homeowners with nearby solar roofs. So presumably there is some benefit to you in terms of cheap generation.
Your last argument could apply to anything really.
Why should I subsidize farmers if they can't compete?
Why do I have subsidize our own manufacturing companies if they can't compete so their workers have a job, at my expense?
Why do I need to subsidize car owners to have yet another lane but can't get a decent train instead?
Here in Poland suddenly all miners pretend to be subsidized by the state, even if they work for private companies.
Why do I need to subsidize them if the companies they work for can't turn a profit, or when they did for decades chose to pay dividends and do buybacks instead of investing? And now I pay the bill?
I mean, at some point you need to cope with the fact that money has to be spent and circulate in some fashion to promote economic activity and projects.
You could argue that subsidizing solar brings energy prices down in any case.
Canada is blessed with cheap energy, the abundance of hydro surely helps to bridge any intermittency other renewables have. I lived there 10 years back, your energy is less than half the cost of mine in Scotland. In Scotland's case we're part of the UK and the rest of the UK is less blessed with the geography for hydro. The incumbent Scottish government also has an anti stance to nuclear.
I hope the incentives for cleaner energy continue to stack up. With the surge in demand from AI surely productivity will be more tightly coupled with energy usage and cost.
In Scotland one issue is that the UK electricity market is national (unlike in eg norway). So even if local supply is very high and interconnects are not large enough to export to england - we must pay the higher national rate. As octopus ceo suggested if the UK energy market has regional pricing then electricity in scotland would often be a lot cheaper and in some cases industrial demand would move there. But that would disadvantage the SE of England so will never happen.
Conversely, standing charges ARE regionalised - because that does advantage the SE of England. Oh well!
Related to UK energy I read this interesting article on transmission congestion between Scotland and England and how this is increasing energy costs due to curtailment of renewables.
TL;DR - Until new interconnectors between Scotland and England are finished in 2029, there will be significant curtailment of Scottish wind power which increases costs.
Ideas crop up like generating hydrogen with the curtailed energy or maybe at least in Winter, use it for heat generation. The problem would seem to be the capex and the inverse of intermittency being the problem for them in utilising that energy, i.e. waiting for curtailment.
At least with available hydro you can pump water back up hill using a reliable and cheap tech.
I find it fascinating that we have not identified a use for almost free intermittent electricity. You'd think there would be plenty of things to do, but it seems like with the capex investment things like smelting etc need to always be running. Maybe electric car charging can come to the rescue? But even there people need their cars charged usually at certain fixed moments.
EV smart charging is a solved problem in the UK IMO, at least for those with a parking space.
OVO[1] and Octopus[2] offer smart charging tariffs that give EV owners reduced electricity rates.
The usual caveat is you can only benefit if you can install a charger and park near that charger. Still, based on this 2021 article [3] 65% of UK homes have at least one off street space, so the potential for a majority of homes to smart charge is there.
To extend the benefit of cheap smart charging to more people, it would be good to see legislation that makes it easier for leaseholders and renters to require the installation of a smart charger where technically possible.
Agree. It seems to be a fairly unique problem that intermittent energy sources introduce.
Charging batteries definitely seems like part of the solution and electricity tariffs that adapt to wholesale costs on a shorter time basis help incentivise it. There are times over weekends/holidays where the wholesale price enters negative territory, essentially paying you to charge your battery.
Electrolysing hydrogen to burn is inefficient vs that kind of thing but at least acts as a battery itself, though there's costs/problems in storing it.
And the general problem of how long do you need to store energy vs what the weather forecast may be.
It seems like it's not a solved problem and it'd be exciting to move towards a point where it is. Hard to believe in the 50's they thought nuclear would solve everything and would be "too cheap to meter"
There is enough wind potential in Europe to power the world [1]. Combined with interconnects to Europe and battery storage, there is no reason power costs can't be driven down. To not do so is a lack of will. Scotland currently generates a surplus of renewables [2], exported. kieranmaine's sibling comment citations dives into the lack of will part.
(at the rate it takes to deploy transmission, might as well start dropping TBMs in the ground and let them grind towards each other from interconnect landings, potentially faster than the approval grind, complaints from locals about land use and right of ways, etc)
The Greener Homes Grant and Greener Homes Loan you describe have ended, but the 160% tarrif on imported solar panels remains. Solar prices in Canada are still quite expensive, and regulations are needlessly strict. Solar fencing is illegal in many jurisdictions, balcony solar is illegal everywhere, and utility-scale solar is effectively prohibited in the regions with the most sunlight.
Solar production in Canada will continue to grow, but we're not doing nearly as much as Europe to encourage it.
I’m wondering out loud if you might be able to purchase what would essentially be the component parts of a solar panel but deconstructed (eg frame, cells, glass, wires; maybe the cells need further deconstructing) and do final assembly in Canada such that the final panel meets criteria to be “built locally”, potentially built of local and imported parts.
Surely local manufacturers don’t use 100% Canadian made parts.
Some provincial grants remain ($5k in BC last time I checked), but yes - Canada can and should do more. Balcony solar seems like such an easy win. Hopefully tariffs get dropped now that we’re talking to China again. And federal Liberals could force municipalities and provinces to reduce some of the red tape surrounding solar installations. Come on Canada, unlocking clean energy shouldn’t have to be a fight!
> Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.
Are you saying that because you assert cost is driven up “artificially” by taxes or other structural headwinds? Or are you saying that fossils enjoy an advantage due to lopsided subsidies? Or something else?
“Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.”
I think a big part of why the US GDP is so high is that a lot of things are just f…ing expensive. Education, health care, solar, restaurants and so on. You have to actively resist the “usual” lifestyle or you end up in a sea of debt.
And that on-roof-solar helps (as it becomes widespread) mitigate the growing need for additional grid capacity. Canada is a big country and, outside the major cities, upgrading grid capacity is quite expensive per capita. It's a win-win in Canada, investing in self-sufficiency while reducing the maintenance burden of infrastructure.
I think the inverse has proven to be largely true. If a home that uses effectively net-zero power is still connected the grid, it becomes a liability to grid stablity and expense.
There still needs to be enough power to supply to all those homes in the event of a protracted time where solar is unavailable. It gets less applicable as homes start to get multi-day battery banks installed, but those are incredibly rare since they are too expensive.
The whole "wealthy homeowners get subsidized solar and then effectively free backup power paid for by everyone else" needs to end.
It may slightly help with capacity, but it causes bigger problems financially. Even if a home uses next to no power, it still must be connected to the grid. The total number of such homes ends up meaning a lot of power lines, transformer stations, monitoring equipment, and people to do all the work.
If you have all of that expense, and suddenly people have solar panels so pay $0 for an energy bill - do you see the problem? The actual cost of fuel/generation is very small compared to the fixed costs.
The more people use solar, the more in the red the utility becomes. You can 'fix' this by making it so every home has a fixed 'connection cost' and then a smaller 'usage cost' on top, but that destroys the incentive for solar panels - they'd never break even for the average buyer.
Solar is great, fantastic even. But it should be done centrally, or people will have to get used to the idea that they will never pay themselves off and are just doing it for the environment.
Where I from, every utility bill has two parts: fixed cost and metered cost. You pay for installed capacity and by the meter for actually consumed kWh, GJ, m3.
It's not a legal problem. The reality is that the vast majority of homes with solar must be connected to the grid because that's how they're wired and designed. You can do a completely off-grid approach, but it's more expensive and requires large batteries. Most people just do the simple panels and don't have any intention of going off-grid.
Also: Even if half of a neighborhood doesn't need the connection, the work ends up being similar. It's more based on distance/area.
If there is no in-house storage to match, how does it help the grid? It is still needed for cold winter nights, where demand is high and solar panels produce nothing. Hydro can provide the power, but the grid will be running at full load.
I live in New England. We do not have enough natural gas pipeline capacity to meet demand in long periods of very cold weather, and have very limited natural gas storage that can't buffer that for as long as a cold spell can last.
In these periods of time the grid traditionally keeps the lights on by switching over a significant portion of the grid to burning oil for power, and/or with the occasional LNG tanker load into Everett MA. These are both....pretty terrible and expensive solutions.
Burning less natural gas during the day still helps at night/at peak, because it means there's been less draw-down of our limited storage/more refill of it during the day, so we don't have to turn to worse options as heavily at night.
Most houses in Canada are heated with natural gas. I'm not negating your overall comment, but in general, cold nights don't strain the grid because of heating needs.
(still good news, as most of Canada's electric generation is low carbon hydro, and the rest of fossil generation can be pushed out with storage and renewables, although I do not have a link handy by province how much fossil generation needs to be pushed out)
450W-500W solar panels are as low as 52€ here in Germany if you buy a couple of them. Batteries are also very affordable and I look forward to them getting a lot cheaper soon, thanks to Sodium-Ion.
People keep saying that prices of panels keep falling, and yet any time I look at getting panels on my roof the price is the same $3/W it has been for 10 years already.
2022-11-28 - “About 2.6 million Uyghur and Kazakh people have been subjected to coercion, “re-education programs” and internment in the Xinjiang region of north-west China, which is the source of 40-45% of the world’s solar-grade polysilicon. A report by the United Nations office of the high commissioner for human rights three months ago found Xinjiang was home to “serious human rights violations”, and the US has listed polysilicon from China as a material likely to have been produced by child or forced labour.”
It's convenient the Islamic countries don't seem to mind their coreligonists being persecuted here, especially as these people haven't launched military invasions of neighboring regions.
I mean I don't exactly have great news for you about the human rights situations in major oil-producing countries either. Not to do whataboutism, but if your energy source is going to implicate you in human rights abuses either way, you might as well take the clean renewable one.
Just to point out, but producing goods in exchange for pieced of paper is a weak system, especially if it's focus is export and not internal consumption, see Germany, Japan, Italy or China, all slowing down due to their reliance on exports.
Another impact on solar adoption in the United States is that many home insurance companies are refusing to pay on claims against roof damage from poor installs. And there are a lot of poor installs, which has led to this problem. So now the homeowners are taking all of the risk on a solar install that already has an 8-10 year ROI.
> Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)
How the heck are the panels even installed and connected for that price? That's about 25 panels, IIRC. What about the installation material and the ac/dc converter?
>Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.
Not just talking about it, if you get a smart meter and sign up for a plan that matches the grid rates you can actually be paid to take electricity during the day right now.
If you're wondering "couldn't you just make bank with a battery" yes you can. In fact Australia dominates the world in grid connected storage (per capita) and this chart itself is actually out of date (it's growing even faster than shown).
For anyone that thinks renewables can't phase out peaker plants it happens very naturally and rapidly once there's enough solar to set rates negative in the day.
We'll most likely see off-peak or dispatchable-demand energy prices become effectively negligible due to cheap intermittent sources, but the price for reliable 24/7 supply will if anything trend higher. Storage is not enough to bridge the gap in all cases, so you need either very expensive peaker plants or less expensive nuclear to provide a reliable baseload supply for those critical uses.
The baseload framing is increasingly outdated. What grids need isn't constant supply - it's flexible supply that matches variable demand. Solar + batteries handle daytime and evening peaks well. Wind fills different gaps. The remaining "firmness" problem (extended low-wind, low-sun periods) is real but smaller than baseload thinking suggests. Most studies show you can get to 80-90% renewables before you hit hard storage limits. The last 10-20% is the expensive part, but that's a different problem than needing baseload for everything.
The quotes for solar on my home in the US ranged between $40,000 (local company) and $120,000 (Tesla). How did you get solar installed for only $13,000?
Those numbers are meaningless unless you specify what you get in return.
It is like saying that you pay $30,000 for a car. But the most important question is: For which car?
Also, if the installation services are so expensive, you can always install everything yourself.
Study how to do it, get the tools and materials, and then do it. It would be time-consuming, challenging and perhaps it would carry extra risks. Absolutely.
But it is not rocket science. It can be done. As long as there is a motivation to do it, i.e. a good value you will get out of it in return, it should be a valid approach to consider, in my opinion.
Most rooftop install costs are labor. The PV is now a minimal slice of it. Which is why mandating solar on new construction is such an important policy: don't make two sets of laborers clamber around the same roof.
What? No Canada isn't cheap solar power -- last I checked rooftop ballasted solar is a 12-14 year payback on avoided costs. Inverter will go beforehand and that excludes any op costs. 8k$ free loan doesn't really provide as much value as you would think.
FWIW - I am all for solar but selling rooftop solar in canada as cheap and no-brainer is false.
3-4 year payback would be a no brainer. 8-13 year payback with an inverter upgrade and op-costs is definitely a decision that needs to be thought out.
The grid you are offsetting is fairly green to begin with so the net benefit is marginal.
If you are going to be isolated and put backup power into the equation. You ROI tanks further but at least you have about a day or two worth of energy in the storage asset.
Anything under $2.25/watt would put it within under a 4 year payback period, Alberta has good rates for solar. Rooftop solar doesn't have operating costs that I can think of unless you want to clean them and clear snow which is optional. And inverters usually have a 20-25 year warranty.
Canada is a massive exporter of electricity to the USA. The more clean energy CND produces the more there is to displace North East's coal.
Of course, solar on Canadians' roof is a joke. A proper regulatory regime would encourage solar in Arizona and encourage lettuce Canada; not vice versa.
I don't disagree but the major energy being exported is from hydro or nuclear. It isn't coming off rooftop even at the margins. Rooftop solar is purely residential play.
If you are trying to argue that in aggregate the demand for energy in canada drops because of high adoption of residential solar which then passes off clean energy to the US - its a reach. Also the amount of individual infra for each small residential asset is probably not particularly great return on investment - would be better to do as large deployments.
You know, when I was researching my system and if it would be worthwhile there were literally dozens and dozens of people who were adamant it couldn’t work here. Too much snow, too tight a valley, electricity already kinda cheap.
I went ahead anyway because I’m a “I’d rather have hard numbers than speculation“ person, and it was literally $0 of my money.
Here we are 18 months later. I have all the hard data, numbers and proof that this system will cost me $0 in the short term, make me over $20,000 in the long term, requires no maintenance and is great.
And yet there are still people like you telling me it can’t work.
I’m proving it does, very well. Panel prices are falling so fast your “last time I looked into it” is woefully out of date.
Talking about hard numbers without a real "hard number" in your comment. 0$ upfront - how much did you pay for the system / what is the size of the system / whats your azimuth and what are you paying for electricity currently. Its super easy to run the math on this stuff - not rocket science - theres even a free to use API that generates your monthly production estimates.
I run energy modeling - I ran the numbers last month with the new programs and newest panel prices. 12-14 years without any op costs and a 3% per year escalator on electricity. You can get it down to 8 years if you have a great spot without having to put on ballasts but it isn't braindead yes for everyone (especially if they have to watch their money).
Current price: 7.6 kW AC; Installed: 26,155.65 - 5,000 Grant = 21,155.65$. << Hard numbers.
We got 7.6kw installed for $13,000 CAD. I ordered everything myself, had a local installer do it on his weekend, paid an electrician $180 to pull permits and actually wire it into the main house panel. All inspections complete and legal.
$5000 grant
$8000 interest free loan.
The system makes 7.76Mwh per calendar year.
Electricity here is 0.13/kwh, and already pre-approved go up minimum 5% per year. It just went up 6% for 2026, 16% for those out of town.
So the system makes right on $1000 of power every year that I don’t have to buy. We’ll put that onto the loan for 7-8 years , then get at least $1000 a year for the 20 or so years remaining of the system life.
I’m nothing out of pocket, and I’m just putting the same into the loan for 7-8 years that I would have paid in electricity anyway, so no difference.
No brainer.
My house now uses net zero energy ( disconnected natural gas entirely)
I have no idea where you’re getting a quote for so high. Even the highest I got was ~$20k, and that was over 18 months ago.
Those numbers are pretty low for Canada (well done on getting a good deal) - though it sounds like you are doing all the work yourself so thats sweat equity and the difference is the margins / work that installers put into the equation.
I don't think what you are providing as an example is what most people are doing. Most people are going through residential installers and not doing all the effort you did to bring down costs.
I commend your effort but it isn't what most people would be doing or paying for and represent otherwise isn't quite honest for people looking to get numbers for their own install.
US also tariffs Chinese EV makers out of the US market so they can keep peddling the fiction that EV sucks or China can't build anything we can't.
This has the same corrupt nexus with the anti-renewable mantra. Essentially subsidize oil and gas under the table and punish renewables then tell the electorate that the latter is worse than the former.
Instead of giving Americans free choice American automakers pay American politicians to prop up their uncompetitive prices and subpar offerings. All while they take in huge private profits. American workers could work on foreign automobiles, just as they do with other automakers not from China. It's not about workers, it's not about national security. You don't even have to go into all the environmental concerns that of course disproportionately affect poorer individuals.
It's corporate welfare. And yes, it should be criminal. At the very least, if the American people are going to inflate CEOs salaries they should have seats on the board.
This is actually not a wild idea. You might be surprised to find who one of the largest shareholders of the Volkswagen group is. It's not like that is an obviously mismanaged socialist hellhole company, it's a perfectly competitive and well regarded car company.
Americans need to start demanding more equity or oversight in operations their governments are already paying for. The fact most Americans think this amounts to communism just means more people have to call out the money is already flowing.
It's criminal to not hand huge subsidies to people like you who are already likely well-off, so you can generate passive income for the rest of your life?
Oil and gas subsidies in Canada dwarf whatever pittance is tossed out to renewable energy. People getting an interest free loan for rooftop solar may be well off (they own houses), but I guarantee the CEO of TC Energy is doing even better.
If enough people adopt solar, it gets cheaper, and everyone get cheaper power, or even free like Australia.
Tax dollars could be spent on new coal or nuke plants, or to incentivize solar installs. Which one is the right future?
Do new coal and nuke plants result in free power like Australia?
Europe has to import both, and the sellers tend to abuse Europe's dependency on it. Europe has what is becoming a survival interest to replace oil and gas as soon as possible.
What is the underlying reason in the US though? You would think if they are artificially inflated prices the market would fix that. What I’ve found is that a large part of the cost is the actual labor for the installation, how are other developed countries getting around this?
It's mostly due to higher "soft costs" such as complicated/slow permitting and high customer acquisition costs. Australia has a higher minimum wage but much lower costs to get a rooftop system installed.
Birch points to Australia, where he said the average 7 kW solar array with a 7 kW battery costs $14,000. That equates to $2.02 per W, with batteries included.
“You can sell it on Tuesday and install it on Wednesday, there’s no red tape, no permitting delays,” said Birch.
...
In the United States, that same solar and battery installation averages $36,000, said Birch. Permitting alone can take two to six months, and the cost per watt of a solar plus storage installation is up to 2.5 times the Australian price, landing at $5.18 per W.
Australia is spending tax dollars to get solar on every roof in the country instead of building coal or nuke plants.
Now people are getting free power as a result.
It's not always a no-brainer. If you live in a good established neighborhood in a warmer climate you'd have to remove tree coverage. Even if you did that, it's the other guys not oil or gas that will make it a hassle.
New panels are much less impacted by shade.
Friends out of town just installed the same setup as ours, didn’t want to cut down three monster Doug firs shading their roof in summer.
Made 6.9Mwh in 2025, only just less than ours with no shade at all.
Shade on older solar systems would impact energy production disproportionally. You would typically see dramatic reductions like 50%-80% reduced output due to 10-20% shade. New shade-tolerant solar systems are closer to being proportional.
This is because a string of panels in series are limited by the weakest link — if one cell is fully shaded, it blocks electricity flow through it, and therefore through the whole string. Bypass diodes mitigate that to some extent. But with electronics costs still falling, it's now possible to use more smaller inverters to connect the solar array to the grid, each one with its own separate string, or even an individual panel (which is a series string of cells).
No one works around physics. You work with physics or you don't work.
What you are describing is adding more solar capability to counter act the shade. Also the other part of it is that the panels work in parallel/not in series or alternatively don't dis activate as many conversion points as possible.
Physics never lies - they are the only laws that you cannot break.
Missing from your calculus is the cost of creating, cleaning, maintaining and eventually replacing the hardware. None of that is "free" - it is merely externalized to a vulnerable population or to your future self.
Missing from your calculus are the healthcare costs of every person in a country breathing in fumes from electricity plants that burn coal and fumes from cars that burn gasoline.
Not supporting OP because I think hes backwards on the matter. However in Canada the electricity that is being burned isn't coal based - so you need to compare the actual grid not some hypothetical grid.
Canada's alternative energy source is very rarely coal (no where near me at least) but a lot of the grid capacity is coming from LNG outside of ON/QC. BC has a bunch of rivers and other water features but has been highly reluctant to build out hydro supply, as an example.
Unlike the UK (which mothballed and eventually tore down its coal power stations) there is still a whole bunch of coal power online in Canada.
Lingan Generating Station would be a typical example. Big thermal power station, built to burn local coal, realistically the transition for them is to non-coal thermal power, burning LNG or Oil, or trees or whatever else can be set on fire. If they burned trash (which isn't really a practical conversion, but it's a hypothetical) we could argue that's renewable because it's not like there won't be trash, but otherwise this is just never going to be a renewable power source.
Canada is a huge place, so I don't doubt that none those coal stations are near you (unless, I suppose, you literally live next to Lingan or a similar plant but just aren't very observant) but most of us aren't self-sufficient and so we do need to pay attention to the consequences far from us.
>there is still a whole bunch of coal power online in Canada.
Ontario, Quebec, BC and Alberta, the four largest provinces by population and a heady percentage of the land area, have zero coal power generation facilities.
Ontario is mostly nuclear supported by hydro, with an absolute fallback of natural gas. Quebec is overwhelmingly hydro + wind. BC is mostly hydro. Alberta is mostly non-renewables like natural gas, but phased out its last coal plants.
If someone is in Canada, odds are extremely high that there is no coal plant anywhere in their jurisdiction. I also wouldn't say that there is a whole bunch of coal power online -- they're an extreme exception now.
To me "a bunch" is when it'd be tedious to list them. For a few years the UK had few enough that you could list their names, then gradually four, three, two, one, none. Canada as a whole isn't in that place yet, though it doesn't have plans to build more of these plants and they will gradually reach end of life or transition to burning something else.
Coal isn't one of the "convenient" fossil fuels where you might choose to run electrical generation off this fuel rather than figure out how to deliver electricity to a remote site, coal is bulky and annoying. Amundsen Scott (the permanent base at the South Pole, IMO definition of remote) runs on JP-8 (ie basically kerosene, jet fuel), some places use gasoline or LNG. I don't expect hold outs in terms of practicality for coal, it's just about political will.
"For a few years the UK had few enough that you could list their names, then gradually four, three, two, one, none"
Sure, it's embarrassing that we still have any coal plants. But really, there are only eight small units remaining, located in the provinces of Nova Scotia (4), New Brunswick (1), and Saskatchewan (3). Every other jurisdiction abolished them.
Maybe small nuclear will be the solution for these holdouts. The fact that Alberta held onto coal for so long, and never built a nuclear plant, was outrageous.
That's a fair point, though I think OP's recommendation to switch to solar is also to people outside Canada and most of the world is still burning fossil fuels to generate electricity.
Not really. People are angry because it is likely their first time hearing a contrarian narrative about solar energy, which likely challenges their own sunk-cost fallacy as solar panel owners.
I have roof top solar. I have never had to clean or maintain them in any way. Same with my friends who have roof top solar. The worst I’ve heard of is a microinverter failing, which was covered by warranty.
My gut response to your post was also aggression, not because you’re preaching uncomfortable truths, but because you’re repeating fossil fuel lobbyist talking points that I’m getting really tired of seeing all over social media.
How long have you had your system - biggest risk point is year 10-12 and then 20-24 on inverter failure replacement which is fixable but just stretches out your payback period.
Im with you I hate the people who preach fossil fuel talking points. I also don't like the shady solar sales people who say solar is a no brainer - they are just pushing product to install on your roof. It is a pretty good product but not 100%.
Simply ask to quantify the cost of shaping those materials into machinery, respective to other means of energy production. You will be met with hostility and scorn, accused of all sorts of improprieties, and ejected from the tribe, without ever receiving a data-supported answer.
Because it's such a weasel "just asking questions" thing to do.
If you had a concern about the material costs of renewables you should know what they are and if you wanted to have a good faith discussion, you'd also be able to compare against legacy energy material costs.
One should definitely think about the children when choosing coal/gasoline vs. full electric. In fact we did and we have an electric car, replaced our gas cooking top by induction, and our gas-based heating by a heat pump. Last time I boarded an airplane was in 2019 I think.
> In fact we did and we have an electric car, replaced our gas cooking top by induction, and our gas-based heating by a heat pump. Last time I boarded an airplane was in 2019 I think.
Fantastic virtue signaling. Of course totally devoid of any mention about the individuals picking raw materials for those electric car components though, since they're not "our" children.
Strange that in your comment history you're all about the democratization of technology, but you seem to be against solar of all things? Talk about decentralized power!
Roof maintenance is a need in Canada regardless of the presence of solar. Solar roofs do demand additional maintenance but the benefits over relying on natural gas for power (which is the alternative in Canada outside ON/QC) is worth it.
I will stand by your statement from the philosophical point of view that nothing in life is free and everything has its trade offs - but this is a pretty clear positive. In addition, Canada has pretty decent workplace safety enforcement for the sort of workers that'd be doing the maintenance - it certainly isn't perfect but it is something that Canadians seem to find important.
Panels have warranties of over twenty years now. They pay for themselves much earlier. You probably have to replace the inverter earlier, but that’s not a huge expense. I don’t know anybody who lives in a place where it rains who cleans the panels on their roof.
Oh, okay. Does a warranty cover sweeping snow off your panels and washing them many times throughout the years? I guess if one does not value time, then solar panels could be considered "free" - but this is a bizarre sacrifice.
Lies. I'm using solar panels since 2022, still producing same peak energy and not cleaned them once. Some companies/electricians will try to sell you a cleaning and maintenance service for ~80-100EUR/year here but it's basically throwing money.
I live in a fairly arid place (Bay Area) where it rains in winter but gets quite dry and dusty in the summer. I've had rooftop solar since 2016 and have noticed that generation decreases by as much as 8-10% when the panels are covered in summer dust.
I wonder if it's worth setting up a sort of sprinkler system so you can easily clean it by opening a valve. Maybe add a pipe with some holes in it to the top of the panel, and some flexible hose to hook it up to the next one.
You’re being extremely argumentative all over the comments to this story. Do you yourself own any solar panels? Your ceaseless naysaying constantly contradicts people’s lived experience (including mine) as owners.
Focus on solutions, not trying to be right. It’s aggravating.
> Your ceaseless naysaying constantly contradicts people’s lived experience (including mine) as owners.
Also, like, every study on this matter. The efficiency drop from being dirty for vaguely modern solar panels is _tiny_; below 5% and potentially below 1%.
I got solar panels installed two years ago and I've washed them once. I'm still getting great production. Are you trying to convince yourself that maintaining solar panels is difficult? Because it isn't.
So let me get this straight, I save hundreds of dollars a month, I drive my cars "for free", I get paid at the end of my net-metering year, and somehow this is a bad deal because I've wanted (not needed) to wash my panels once? It sounds like you optimize your life around not maintaining the things around you which is fine, but I'd much rather save thousands of dollars.
You don't bother with the snow. Winter is low production energy due to the suns positioning - it melts in the spring and your back to producing. Most solar power is between march - september anyways.
Washing solar panels _at all_ would be fairly unusual, and arguably pretty pointless, particularly given they're so cheap now; you're looking at, optimistically, a 5% efficiency improvement, but many studies say more like 1% in practice.
If you're in a place that gets significant snowfall such that they're often covered then production during winter is likely to be fairly marginal anyway, so may not be worth your while.
Solar panels last practically forever. Despite the official lifetimes of 25-30 years, that was a conservative estimate for budgeting purposes, and they're still working after that time, with moderately reduced efficiency (around 70-80%).
I've had my system for 10 years and maintenance has literally been 0. Rain and snow clean the panels. Panels themselves warrantied for 30 years but will likely last longer.
Roof-based panels also take on some roof wear, increasing longevity of roofing as well.
Every time, over the years, that there has been some kind of headline saying renewables have overtaken fossil fuels, when you look at it a bit more closely there is always a big 'but'. For example, it was compared to coal (not taking into account electricity from gas), or it was for one day, or it was a percentage of new installations, or it excludes winter, includes nuclear etc.
This time, however, it looks like it's actually true and that's just for wind and solar. This is incredible, and done through slowly compounding gains that didn't cause massive economic hardships along the way.
The only asterisk this time is that this is electricity, not energy. Still impressive, but electricity is only 22% of total energy use, so they are at about 12% of the total for the EU and 7.8% for Europe.
Fun to play around with, you can also change the selection to view the world, US, China, individual EU countries etc.
You can see that this the gain in renewables in the EU has been mainly at the expense of coal (down >50% as a share of total energy use in 10 years), gas (down 4%), and nuclear (down 20%.) Oil use as a share of the total is up by 5%.
It can be rather misleading to to talk about renewable energy generation versus total energy usage.
Most uses of fossil fuels are very inefficient. For instance, when you step on the accelerator in your car, only around 30% of the energy in the fuel you use actually is being used to propel you forward. The majority of the energy is wasted as heat. In a power plant that's more like 70% being captured and going towards the goal (electricity generation).
Another large quantity of energy-usage is heating, and electrical heat-pumps can be around 3-5x more energy efficient at heating an enclosed space than combustion or resistive heating.
So while things like heating an transportation use a very large amount of energy, conquering them with renewables actually won't require that Europe installs 10x or whatever more wind and solar, since electrification also brings significant new efficiencies.
______
If you want to compare renewables against the amount of fossil fuels being burnt, then it'd be a lot more representative if you calculate the amount of wind energy impacting a wind turbine blade, or the amount of energy in solar radiation incident on a solar panel. That's an easy way to inflate the renewable numbers by ~5x or whatever
I mostly agree. Certainly transportation is an obvious one. But of course there are still some losses; when you include all the losses in the system and cold weather you can easily get ~80% for EVs vs. ~30% for ICE cars. Heat pumps can be very efficient, but 5x more efficient than combustion/resistive heating (which is near 100%...) is not common in practice. 3x, sure, plenty of installations that get that or better in mild climates.
That said, those are two pretty large items. If we reached 90% electrification on both it would be a pretty big win: Road transport represents ~26% of global energy use and all heating/cooling (industry, building, agriculture) represents ~50%.
Exactly. It is in general (much) more efficient to burn natural gas in a power plant and use the electricity for heatpumps compared to simply burning gas at home for heating.
This is an important observation. For years these headlines came with asterisks - one sunny/windy day, excludes gas, new capacity only, etc. This being actual annual generation for wind+solar combined vs all fossil fuels is genuinely significant. The compounding nature of it is key too - solar capacity is now large enough that even modest percentage growth adds enormous absolute capacity each year.
In my opinion, the "but" is still the "hellbrise" considerations brought up in the Decouple podcast. Renewable energy is fantastic but, at grid scale, has to be coupled with sufficient storage: https://www.decouple.media/p/hellbrise
You can get pretty far with negligible storage. There is a cost tradeoff between storage, peaker plants (those could burn hydrogen, not just natgas) and grid size. 70% renewable with no storage is rather easy.
Not sure if you read the podcast but the whole point is that over-reliance on renewables without a sufficient means to handle oversupply can cause grid instability specific to the Spain/Portugal grid outage.
Sadly we got a warning in 2014 with Crimea being seized and fossil apologists like Bjorn Lomborg argued against rolling out wind and solar faster in response.
Because he's so "reasonable" and "pragmatic", he didn't say we shouldn't phase out Russian gas, he just said solar and wind don't work and so we should invent some totally new type of energy for this purpose.
It's only with a few years hindsight that he's obviously a shill. You had to be paying close attention at the time to notice.
And sadly that kind of engineered delay is widespread.
The most underreported part of this story is the battery piece at the end. Batteries are beginning to displace natural gas in evening peak hours - that's the exact window where solar critics have long argued renewables fall short. If this trend accelerates (and battery prices are dropping faster than most models predicted), the "intermittency problem" starts looking more like a solvable engineering challenge than a fundamental barrier.
The next milestone to watch: when battery-backed solar becomes cheaper than gas peakers for evening demand across most of Europe. We might be closer than people think.
Intermittence really has always had the flavor of an engineering problem instead of a physics problem (it is about putting the energy when/where humans want it, rather than having enough of it). IMO load shifting seems like a cleverer and more engineer-y solution. Imagine a giant smart system where all of our appliances talk to each-other and can optimize the timings of their workloads. It’s a magnificent society-wide scheduling problem! The papers we could write!
Throwing batteries at it is a kind of blunt and uninteresting solution (I guess the market will prefer that one!).
I ain't gonna use the dishwasher when the system wants me to, but when I can or want.
I pay low energy prices during night than day, that's normal, but I'm still not gonna do laundry at 9 pm, I'd rather pay the 10/20 cents more during the day.
If I had a combined washer/dryer and could just load the clothes up and say “do it whenever” I’d go for that. But that’s very dependent on only needing to do one load per day.
In engineering the simple solution is often the best solution. Creating a demand-side network of devices is not that.
Plus, such a system would provide even more ways for nefarious actors to sabotage the grid, by influencing the demand side. For example, setting every appliance to run its load at the same time. The grid would be fucked.
I looked into sodium-ion batteries for which factories are coming online in China. The theoretical manufacturing cost of those is very very low, which will make solar + batteries very cheap. I suspect China will reach those costs ahead of schedule.
IMO this is a classic case of underestimating how far manufacturing improvements can get you on the cost scale. You see a promising technology in the lab and it’s hard to imagine a 1 million x reduction in price, yet we see that time and time again as tech gets scaled out.
What’s wild to me is how the US is leaving itself in the dust. How the GOP imagines we’ll be competitive when the rest of the world can produce electricity 10x cheaper than we can is a wonder in itself
I mean where are all the factories making batteries in Europe? It’s not like the US is purposefully preventing battery tech. It’s why all of the government-funded solar companies imploded as well. The manufacturers do not compete
Those are two thresholds: cheaper than peakers using piped gas from Russia, and cheaper than peakers using LNG shipped via tanker ship. I imagine the latter threshold has already been met, only depending on the amortization period you choose for the battery purchase.
The problem with solar isn't the night. Getting enough batteries to cover that is totally doable. The issue is the winter. And not even because of fewer daylight hours - on sunny winter days there is usually still a good amount of solar.
The problem is its often very cloudy in the winter. In the UK in winter we regularly have periods of 5 cloudy days in a row where solar output is virtually zero.
I don't know what the answer to that is. In a calm cloudy winter week all renewables and battery storage are totally screwed. Space based solar is a scam. Maybe we just have to live with it until fusion works (if it ever does).
(But it's still academic at the moment because we're still far from the point where building more renewables is a bad idea.)
> the focus of energy storage has shifted from frequency services to energy arbitrage. Due to market saturation, the share of frequency services in the revenue stack has significantly declined, from 80% in 2022 to just 20% in 2024. Looking ahead to 2030, we expect energy arbitrage to dominate the revenue stack, with most revenue coming from participation in the balancing mechanism.
The article uses the words "more power" and "overtaking fossil fuels", but the graph is actually about electricity generation. They are not the same thing, at least, in my head, because not all energy consumed in Europe comes in the form of electricity. If I heat my home with natural gas and drive an ICE car, this is me using fossil fuels in a way that has nothing to do with electricity and it won't be reflected in that graph. This is an important stepping stone, but it is not "solar and wind overtaking fossil fuels in Europe"
Good catch. Electricity is maybe 20-25% of final energy consumption in most EU countries. The real test is whether cheap renewable electricity can pull heating (heat pumps) and transport (EVs) onto the grid fast enough. The encouraging sign is that both are happening - heat pump sales have surged in several EU countries, and EV adoption is well ahead of most forecasts from 5 years ago. But you're right that "overtaking fossil fuels" in total energy is still years away.
It used to be the big worry among climate activists that you'd never get every country organize and move in one direction. Like you'd need some global body to clean everything up.
That's very fragile.
Luckily, we're moving to a world where a disjoint, self-interested response can be an advantage. Countries decide, for their own selfish reasons, to adopt green energy. For energy independence, affordability, clean air, etc.
So when one country politically rotates out for dumb reasons, other countries pick up the slack and make a bit of progress.
Curious if this will eventually change China's calculus with regards to Russia. If Europe is a big customer for Chinese exports, and Russia is antagonizing, it seems like China would have an incentive to put pressure on Russia.
It already seems like Russia is positioned to be completely subservient to China in the future.
China is happy as a clam that Russia is self-isolating and destroying their internal economy. The natural resources of Russia are vast and if China is the only one exploiting them and funneling them into the Chinese economy it'd be an excellent outcome. I don't think China is opposed to strong economies as trade partners but dependent economies are much easier to control and monopolize.
Russia is only isolated from the west (e.g. exports to India are booming) and its internal economy is growing faster than Europe's.
Russia holds leverage over China because China is incredibly resource dependent and very susceptible to the threat of blockade through the first island chain by the US. Only Russia can bypass such a blockade with fertilizer, grain, oil and gas.
The US is driving these countries into each other's arms.
It worked until it didn’t. That’s how it goes. Peace is always hard work and irrational actors (in terms of: well being of people, not necessarily aspirations of empire) can muck everything up.
Economical co-dependency is a good tool for increasing the price of going to war and making it irrational. It’s also not a zero sum game and tends to profit both sides. However, it can suck if you do it with non-democratic regimes and autocratic rulers who trample human rights.
So between France, Germany, Poland and all the other EU members it‘s keeping the continent at peace and generally does not suck because it‘s between broadly democratic nations. It also benefits each one massively and makes things possible like a common electric grid that increases reliability in general. So nearly all upside.
I do think economic cooperation with the Soviet Union and later Russia - much, much more limited than between EU members - was helpful in cooling tensions and making the world a bit safer, sure, but Russia has clearly behaved in a way that makes that no longer a good idea.
It also works the other way around and I am pretty sure that was what Russia was betting on - with Europe's dependence on Russian energy, Europe would not react strongly to Russia's invasion.
China is usually seen (I think broadly correctly) as more of a rational actor than Russia. Russia is much more run for the benefit of a weird dictator than run as a country.
Europe was a bit customer for Russia energy, and Russia invaded an EU neighbor nonetheless. After which it stopped being the customer. So it seems like that incentive didn't really work.
I think that was raincole's point. I guess we can't account for Russia or the US making decisions that are completely counter to the benefit of their people.
Russia did have a big incentive to not antagonize Europe.
But sadly they have a political system that doesn't reflect what is best for the ordinary person. So those incentives can be ignored by those making the decisions.
> If Europe is a big customer for Chinese exports, and Russia is antagonizing, it seems like China would have an incentive to put pressure on Russia.
China wants Russia to at least keep the Ukraine war going, if not eventually win the darn thing. Russia winning (or getting away with an armistice that lets them keep Crimea and Donbas) means a precedence China has for a land-grab of its own - obviously Taiwan, but other countries in its "sphere of influence" have seen hostilities for years, from land grabs [1] to overfishing [2], not to mention the border dispute with India.
And as long as we are distracted with Israel/Palestine or Ukraine/Russia, China has free rein to do whatever they want.
Chinese Foreign Minister Wang Yi visted Europe and openly said to Kaja Kallas, the European Union's foreign-policy chief and other EU ministers: the Chinese Communist Party (CCP) does not want to see Russia defeated in Ukraine, fearing that the U.S. would then shift its full attention toward Beijing.
Donbas is mostly wheat fields, Taiwan is mostly SOTA semiconductor fabs that currently are the sole pillar holding up the AI (and compute in general) zeitgeist.
The global response would not be the same, even remotely. And what would China get from it? A tiny island of rubble and an ego boost, while losing enormous global favor? The cost of that island may well be a few trillion for China, just so they can say they defeated the nationalists.
The semiconductors are propping up the AI zietgeist in the US, but is that true globally? Why would Canada/Brazil/Europe care about Taiwan? China will still sell them the chips.
The only one who would really care is the US. So by taking Taiwan, China blows up the US stock market and takes control of the chips.
Every country on Earth benefits from the chips that come from Taiwan, and not just the governments, the people using pretty much anything that does computation. That includes China.
Yes I am aware. Which means that if China takes over political control of Taiwan and says, "We will still sell chips just like normal to everyone except the US".
Would the rest of the world decide to go to war with China for the political freedom of Taiwan?
China is playing the long game. They can go spend a trillion bucks and hire/steal the tech and they could destroy Taiwan's competitive advantage, and they could just economically crush them.
... which nevertheless are very important worldwide. Early in the war, there was a lot of effort to make sure grain exports could run smoothly because otherwise Africa would have been in serious trouble.
> The global response would not be the same, even remotely.
We're already at a stage where Trump doesn't give a single fuck about NATO and some of his advisors would rather have it disbanded yesterday in favor of isolationism, or even outright march into territory to annex it. I have absolutely zero faith that Trump would intervene on Taiwan's favor - an intervention does not fit into Trump's and especially Miller's world view wherein the world is to be divided into areas of influence for the super powers to act with impunity.
> And what would China get from it? A tiny island of rubble and an ego boost, while losing enormous global favor?
Never underestimate nationalist idiocy. Putin invaded Ukraine because of his dream to restore "Great Russia", it is entirely possible that the CCP wants the same for the ego of their leadership to be the ones "bringing the lost areas home". They already did so with Hongkong, and not reacting to China violating the treaty with the UK was the biggest mistake the Western nations have ever done.
The consensus among Western defense and foreign policy types is that China will most likely invade Taiwan in 2027, relative to any other single year, conditional on them doing it at all.
I don't think that mainland China needs any sort of precedent over Taiwan should they decide on military action. The situation is completely different from Ukraine. The South China Sea is also on long-running dispute that predates the PRC (and dates from a time where all the neighbouring countries were Western colonies...) and what has been happening is more a policy of "fait accompli" by occupying unoccupied disputed islands first rather than an "invasion".
I don't know what is the thinking on Ukraine now in Beijing, but they were massively pissed off when Russia invaded because it has caused a lot of disruption to belt and road and to East-West relations in general.
I'm curious as to how this will shift once the shift towards more electrification continues. This is only about electricity generation, not total power consumption.
Nowadays, for very energy intenive things like heating or driving a car, fossil fuels still are more prevalent than electric alternatives. Once demand shifts in favor of the electrified alternatives, electricity demand is continuing to raise (although not as steep as the drop in demand for the fossil fuels will be). Particularly in heating, where peak demand is in times with very little solar generation, it seems like this will be challenging.
While the prices of energy storage have come down significantly and are projected to continue to drop, there is still a noteable lack of cost effective long term storage solutions.
> Particularly in heating, where peak demand is in times with very little solar generation, it seems like this will be challenging.
Heating is actually likely to be one of the easier questions here, because heat is just fundamentally an easier problem to tackle than most other intensive uses of energy in the modern world.
1. Solar isn't the only incredibly cheap form of intermittant renwewable energy production. Wind is also great, tends to support local manufacturing economies more than solar, and is anti-correlated with peak-sunshine. The wind tends to blow hardest in the winter and around sunset.
2. Heatpumps can pretty comfortably achieve 300+% coefficients of performance, meaning that for every joule of energy you put into a heatpump, you'll get 3+ joules of heat pumped into your home, office, or city-scale heat thermos
3. Heat energy storage is cheap compared to batteries. You just store large quantities of water or sand and heat it up with a resistor or a heat pump. The scaling of surface area versus volume ensures that the bigger you make the heat-battery, the less energy you'll lose from it over time (percentage wise).
4. Heat is a waste product from many other forms of energy usage, and can be harnessed. For instance, gas peaker plants aren't going away any time soon, and cities which aren't harnessing the waste heat from those peaker plants and using it in a district heating system are wasting both money and carbon.
Just a couple kilometers from my home for instance is a gas power plant that stores waste heat in giant thermoses, and pumps hot water to my building to to be used for heating. They currently have the largest heat pump in europe under construction on the same site intended to supplement the gas plant, both to take up slack from the fact that it'll be running less often, and to expand the service to yet more households.
Regarding the affect of EV adoption on electricity consumption the site https://robbieandrew.github.io/EV/ has some interesting data. I'd recommend looking at the following graphs:
* Distance travelled by passenger cars in Norway
* EV electricity consumption and total power generation in Norway
EVs now make up approximately 1/3 of miles travelled, but the increase in total electrcity consumption is fairly small.
If you’re interested in this topic I highly recommend Tony Seba’s analyses.
He argues that because solar and wind are now the cheapest forms of new energy generation, they are on an unstoppable exponential "S-curve" that will make coal, gas, and nuclear power obsolete by 2030.
Imagine the powerhouse America would be (pun intended) if we subsidized nuclear energy to become the defacto producer of nuclear power plants world wide. Sometimes it is easier said than done but this really is as easy as said.
The US gave the nuclear industry a chance for a nuclear renaissance with the subsidies they asked for towards the AP1000. The industry whiffed big time. Looks like nuclear will get another chance with the increased subsidies begun under Biden, the deregulatory approach of Trump and the huge demand spike in electricity. Its an open question on whether they'll be able to deliver.
Correct me if I am wrong but the only reason nuclear is expensive is because of how costly the facilities are to build and maintain. If we were not setback during the anti-nuclear era, we would have gained economies of scale. The reason why solar is so cheap is for the exact same reason is it not? I am not an expert on this topic so take everything I say with a massive grain of salt as I am willing to be wrong on this.
Edit: After further reading it appears that solar will be the defacto affordable option in energy production, even with SMRs and streamlined construction in the picture. Perhaps a mix of renewables, better battery infra, and SMRs for stable sources of power is the future.
Power plants with high capex like nuclear have a hard time competing in a market where power is essentially free when it’s sunny or windy. Running something like a nuclear power plant only for a few hundred hours a year when it’s neither sunny nor windy is too expensive compared to (hydrogen) gas peakers (or other forms of storage)
nuclear can compete if we re-learn to build on time and on budget. Japanese abwr did cost 3bn and done in <4y. China does the same now for cheaper.
There's no such thing as free hydrogen, nor it will be
Solar with a modern LFP battery system is a no-brainer solution for 21st century energy infrastructure. The safety record beats pretty much everything else, and as long as the sun is out, it just works.
Focusing on Solar+Battery is only effective when the solar is not accounting for a majority of electricity generation (at least in geographies significantly north of the tropics). The problem is that while the sun shines, solar will drive everyone else out of business, but then leaves you stranded in the winter, and no practical amount of electricity storage will save you.
Fortunately, wind energy generation also exists, and is a nearly ideal complement to solar power, because it's nearly as cheap as solar, and its energy peaks are mostly anti-correlated with solar energy peaks (typically the winter and sunset are the windiest parts of the year / day).
Wind's main problem is that it's more reliant on large scale projects (rather than solar which scales all the way from a pocket calculator to an installation the size of city), and wind is also more susceptible to regulatory / NIMBY sabotage than solar.
Especially with China currently flooding the market with cheap solar and batteries, I think it makes sense for governments to focus much more of their attention and efforts on promoting (or at least getting out of the way of) wind projects, and let the market drive solar adoption.
In the UK just having batteries already helps. There's a surplus of wind at night. Shifting it to 5pm peaks pays back the cost of the battery quicker than solar panels pay for themselves.
Encouraging. However, it isn't clear from the article at first glance (or the deeper analysis being referenced) how electricity consumption by power source is changing.
In other words, as an example, a 10% increase in solar power generation does not necessarily mean that there was a 10% increase in electricity consumption where that electricity was generated via solar.
i.e. It is entirely possible for a growing solar fleet to generate more power during the middle of the day than previously, and simultaneously for not all of that increased power to be used / usable.
What you're talking about is commonly called "curtailment", where power generators like wind and solar can be told to basically stop feeding into the grid, effectively wasting their energy.
From what I recall, curtailment of wind and solar at least in Germany amounts to about 3% wasted energy from those sources, so no, it's not a very significant worry. These renewable sources really are displacing fossil fuels.
A big part of this story is batteries. Especially during the summer, the wholesale electricity price in Germany can swing daily from -10 to +10 cents per kWh during the mid-day, up to 150+ cents per kWh at night, due to supply-and-demand.
This gradient in prices creates a huge incentive for people to build batteries that buy up cheap electricity during the day (sometimes literally getting paid to do so), so that they can sell it back later on in the day when prices rise. This incentive helps make sure energy does not get wasted, it encourages more batteries to be installed, and it encourages businesses to shift the their energy usage to times of the day that align with high renewable output.
that's true, but hardly relevant for the grid, especially considering many ppl dont even have a battery and have grid following solar panels which shut down the moment grid is down
At the same time subsidies are being phased out. I was about to get 8kW panels + batteries installed when my country decided to pull them, and I'm not going to spend 10k out of pocket.
In Davos yesterday, our great leader was gaslighting the audience to believe that Europe buys wind power equipment from China whilst China themselves do not believe or use the very windmills they sell.
At the end of the day, the retail cost of electricity in many EU member countries can be two to three times the cost of electricity in the US.
Ultimately that’s what matters to consumers and businesses.
Also, Trump called out the idiotic decisions by greenies such as shutting down nuclear power plants and make long your industries less competitive as a result.
> in many EU member countries can be two to three times the cost of electricity in the US.
Yup, I wonder why that might be, perhaps its due to our main supplier of gas and oil invading a country. Not sure though, if only the price graphs reflected that. oh wait.
> shutting down nuclear power plants
Germany fucked up there. but france and Finland haven't done that.
Spain has cheap electricity because of solar power its wholesale price is currently lower than the US, in winter.
If this is true, it has nothing to do with solar or wind but rather strange decisions in the past in some countries that they (and their neighbors) pay for now (looking at you Germany).
Nuclear does not cause prices to be lower. Putting that aside, political discourse here in Germany was "interesting" to say the least.
The shift to renewables started off pretty well in the early 2010s before it came to a grinding halt thanks to some wierd debates around the topic. For the past few years, buildout of solar has been remarkably fast, especially considering the slow pace of other projects. In 2025, 16.4 GW of solar power went live.
The biggest issue that drives prices here is the grid. New high voltages transmission lines have faced intense local oppsition, so transmision between North and South is limited, which is problematic given the focus of the north on (offshore) wind and the south on solar PV. Since Germany is a single electricity price zone, the low to negative electricity prices from wind turbines do not reflect the reality of grid capabilities, resulting in significant redispatch costs.
The solution would be obvious. Split Germany into n electicity price zones (with n>1). However, there is a lot of political opposition, specifically from the conservative CDU/CSU against this.
So yeah, Germany is struggling with relatively expensive electrcity prices, complaining about it, but refusing to implement a borderline free solution for it.
Nuclear that was built a long time ago would probably have lowered the prices in DE right now, if they weren't shut down. I understand that building new ones right now makes little sense.
Refurb costs are for the entire fleet which is 50+GW and are in fact dirt cheap. Refurbs are in 1-3bn/unit range. CF of say solar in this region is roughly 10-12%. To have same average output as a single 1GW npp you would need about 10GW solar and much more if you want to achieve firm generation. French refurbs will happen anyway. In fact, carenage is already undergoing.
Nuclear was cheapest firm power in the german merit order. So yes, nuclear does have an impact, especially if it outplaces higher cost units
There is a lot of opposition because zone split would mean erasing southern industry and I may be wrong, but southern regions are pumping most of the money into state budget. Cutting those means cutting own legs.
The high voltage DC transmission lines from north to south are being built right now and for example SuedLink is expected to be operational in 2028. Their transmission capacity will be more than enough. Why would you split Germany into electricity zones now, if in a few years the transmission problem will largely be fixed?
Declining industrially and demographically, no innovation, soaring energy prices, and our share of the world economy has shrunk for ten years straight and is projected to continue shrinking in the future.
By all metrics us europeans are losers.
The graph I see in the article displays a single data point per year. You're not going to see seasonal variation in a graph with that resolution. Is there another graph that I missed?
I don't see any energy security for the future for the UK unfortunately. We sold ourselves short during the GW/Blair Neo-labour era. Scotland maybe, they have wind-farms but the UK likes to tax that. We've just started the era of paying for the cost of Brexit. It's hitting hard.
My weekly supermarket shop for the basic essentials (cheese, eggs, flour, vegetables) now come to around $60/80 a trip.
Parmesan Cheese is around ~£22-£45 ($30-$60) per kg compared to the US $7–$24+ per kg.
Why not? You've got abundant wind and solar. Once installed, even if for some reason you can't get new turbines or panels, you'll still have a decent amount of capacity.
Solar is hit & miss. The only capacity we really have is wind and those are only efficient to those near the sea or in the highlands. England, Scotland, Wales are governed by rain 80% of the year and with the sun we get, household solar rarely breaks even.
Just because we've got, if the government isn't supporting it's pretty much wasted. The renewable farms we do have are mostly funded by private investments firms. Scotland and Wales wants more renewable but the UK government says no.
mate, I dunno what your smoking, but it deffo does. I'm about 50% "paid off" and I had an expensive setup. Installed now the equivalent costs about 50% of what it did.
> Scotland and Wales wants more renewable but the UK government says no.
National grid say "holy shit I need to build more cables" then local people say "ewwww pylons" and shit gets more expensive. There is a bottleneck between england and scotland, which is partially being solved by https://www.nationalgrid.com/the-great-grid-upgrade
The whole boo england, poor scotland/wales thing gets tired super quick. its being solved, is it being solved fast enough? no, but thats because we have a raised a shit generation of empty politicians from across UK and NI. (and the co-dependent pundit class)
> The renewable farms we do have are mostly funded by private investments firms.
Mostly pension funds. but yes, private. However given the high turnover of (useless) polticians, and a civil service that has had all is expertise hollowed out and replaced by consultancy firms, I don't think public funding, without structural reform is a good idea (look at railways for example)
A quick search says the UK produced 18,314 GWh of solar last year. And this was mostly funded by private investment? It seems like for some infrastructure investment, the government is getting long-term renewable power. If the solar isn't making money, why is it growing 30% annually?
What is stupid about nuclear? It's a huge amount of clean, secure energy.
Would your preference be dependence on Russian/US oil natural gas? Would you feel the same if Russia invaded Finland/Baltics and US took over Greenland?
> What is stupid about nuclear? It's a huge amount of clean, secure energy.
It's not the stupidly of the reactor producing. I don't agree with it personally, but hey whatever, it's a thing. The stupidly of it is that we are small island.
Claim what you wish about how safe they are but like anything: errors and malfunctions. Cyber sabotage and all that.
If an reactor were to implode we're eff'd. We don't have landmass to facilitate the output waste in the UK and the waste we do currently produce has to be shipped elsewhere; sold for dark money.
> Would your preference be dependence on Russian/US oil natural gas? Would you feel the same if Russia invaded Finland/Baltics and US took over Greenland?
My preference would be my hand with a gun pointed at my temple and myself pulling the trigger. To dark?
Forgive me, but I don't think you're looking at UK energy policy with a pragmatic and realistic lens. The UK could always make a reactor safer and more secure. If you're dependent on gas, Russia or the US could just shut off the tap.
even accounting for fukushima/chernoble nuclear is between solar and wind in terms of human deaths. And new units are safer than both. EPR went 'just add one more thing' to be more expensive, AP1000 went passive safety way but westinghose imploded and they needed to ask Korea for help
If either one of the two alternative government parties of the UK get in they will scrap all. Reform UK sets out plans to tax renewable energy, conservatives are all for the oil.
2030 is four years away & the next election is in 2029. The Labour party is unlikely to get in again, and if they do it'll be a miracle. Far-Right or Fascist Right.
Reform UK won't get enough seats to sit in parliament this election but if in the future, it's a dystopian vision I don't want to think about. Trump-XL, tax the EU, climate change doesn't exist, kick out asylum seekers, higher taxation to further screw Scotland and Wales. Heavily back pocketed by the US oil and tobacco industry, Nigel is foul MAGA of the UK.
Conservatives, sponsored by oil and pharmaceutical. Exxon, Esso, BP et cetera. They got their wish with Brexit, they made a bucket load of cash from that and they're the ones who scrapped the renewable industry in the first place. One of their aims is to scrap the NHS and make it privatised.
> A supermarket shop for the basic essentials (cheese, eggs, flour, vegetables) now come to around $60/80 a trip.
No it doesn't. Maybe if you are shopping at Waitrose. It is more expensive. But it isn't £45 for basics. I did an entire shop which will last me the week for £30 (in Aldi).
I shop at Sainsburys where I can. The main supermarkets for me are Morrison and kind of forced to use M&S.
Everyone has their super market preference. ASDA would be cheaper still. You can't disagree that prices have sky rocketed, shrunk in quantity and now lower quality.
This is a glib statement that disregards a massive amount of complexity.
Energy is not expensive because of Net Zero taxes. Here's a breakdown of the average UK electricity bill over time [1]. The Renewables Obligation, that subsidised wind and solar at a time when they were infeasible without subsidies, was a scheme that ran between 2002 and 2017. It was stopped once renewables became cheaper than the alternatives. We will continue to pay for the renewable plants set up back in the day, but this will gradually taper off. In this electricity bill estimate for 2030 [2], you'll find that the Renewables Obligation is much lower (£17 rather than £102) for two reasons: plants losing subsidies as they age out and a chunk of the subsidy being borne by the treasury from general taxation.
So why aren't electricity bills coming down? Because we're recognising the reality that we will need to be powered by a mix of nuclear, wind and solar. Check out this real time dashboard of electricity generation in the UK [3], which shows you how Wind has zoomed in the last 14 years. From 2GW to 14GW, wind is now the single largest source of energy generated in the UK.
Wind is only going to grow, because it is cheap compared to the alternatives. In the Jan 2026 auction for wind power, an 8.4GW contract was awarded for a price 40% lower than the cost of a gas power plant. And unlike gas you aren't at the vagaries of global gas prices, like we were in 2022.
And now you're thinking, if wind is so cheap and we're continuing to build more, why is the estimate for the 2030 electricity bill higher than 2025? The 2030 page explains this - the wind is being built in the North Sea, far from where it is needed - in the South of England. This means investing in the transmission network, which will cost £70B over the next 5 years. That cost will be passed onto consumers.
So no, bills aren't high because of renewables. The decision to double down on wind, solar, batteries and nuclear by the previous and current government are sound. We will be more energy independent than we were in 2022 and possibly paying a bit less in overall bills. The reduction in carbon emissions is a nice bonus.
The social and environmental cost part is being removed in April and should save around 15-20% of the bill. I guess that is what you mean by net zero taxes?
No. Citation neede. The issue is the moronic way energy auctions are done, first by setting the price to the highest source that can satisfy (always gas) but ignoring (!) geography. Then, phase 2, dropping the impossible providers (i.e. Scottish hydro in the North for South England), and doing another (much more expensive pass). The Octopus CEO had a succinct explainer recently, can't find the video...
this is not moronic. This is done everywhere in the world.
In fact, merit order does justify more ren deployment even if economics aren't that great, because operators will be paid according to merit order, needing less cfd's. You can also check out how much of the gas electricity price is just carbon tax. And how transmission spending evolved. And how CFD's for different tech evolved in each AR round
Now we just need to figure out scalable storage. Ideally something like the sand batteries that you can scale with construction equipment rather than just adding more rows of tiny lithium batteries
The answer is likely going to have to be hydrogen, but there's a pretty difficult catch with hydrogen: it makes zero sense to invest in any hydrogen electricity storage infrastructure until the grid is already like 80+% renewable.
There's simply no sense in turning electricity into hydrogen so that it could be used in 6 months (losing 50+% of the energy along the way as heat!) when you could just sell that electricity right now, or stick it in a battery so you can use it 6 hours from now.
There will be an economic case for hydrogen energy storage in Europe in 10 years, but unfortunately the technology is basically sitting at a standstill right now with no attention and no investment because it's not needed yet.
even in 10y h2 is economically unviable. Check out Norway/Sweden, they got tons of ren. Are they some _cheap_ H2 generation meccas? There are some chances for other synth fuels but H2 is just a pipedream
Norway and Sweden have tones of renewable energy, but relatively little intermittent energy. If the economics of H2 ever work, it'll only ever work in a grid that's driven by intermittent energy sources (wind and solar).
A hydro-driven grid does not need storage. Hell, if you have enough hydro, it can even be your storage. Not all of Europe has the geography to be able to cover their needs with just hydro.
H2 economics work if you have constant oversupply. If your electrolyzer works only 50% of the time and storing is expensive, transporting is expensive and roundtrip efficiency is abysmal, it'll still cost a ton. Higher chances to use just cheaper gas generation because even LNG is cheaper than H2 saga.
Not a constant oversupply because then you'd never need the hydrogen in the first place. H2 economics (if they ever work) will work in a place where there's a seasonal gradient in energy production that's over too long a time horizon for batteries.
Per lazard, currently, merely 25% green H2 peakers would provide power for as expensive as worst nuclear project in US- Vogtle. So a mere 1/4 mix is as bad as a terribly mismanaged construction project. H2 economics for electricity are non existent. It will be used fo other sectors maybe, like fertilizers
Look, I don't really want to be in the position of defending H2 here as I'm not particularly confident or optimistic about it, but I'm not really currently seeing a better alternative for seasonal energy shifting.
If Germany was willing to build new nuclear power plants I'd be in favour, but it's looking unlikely to happen, so H2 will likely be the way, and it won't be cheap.
That said, I also invite you to go look at cost estimates for batteries from just 5 years ago and compare them to today, or solar / wind cost estimates from 15 years ago. Those technologies have experienced significant reductions in cost due to scale and industrial learning.
IMO the biggest problem with H2 is that similar sorts of learning / scaling processes simply won't even start until the grid evolves to a point where the seasonal demand shifting is actually required, but by then it's essentially too late. And there's not really any hope of governments kickstarting the learning process with artificial demand because people will make all sorts convincing arguments for why it's a stupid waste.
So I guess we'll see what happens. Perhaps stuff like fertilizer and steel will help the technology matures before the grid needs it, or perhaps battery technology will surprise us again, or someone will figure out how to make flow batteries work or whatever. I'm not particularly confident in any of these technologies, but we'll just have to wait and see what happens I guess.
Something *does* need to be done about storage though, even with all the complementary wind-solar and giant Lithium or Sodium battery installations, and all the HVDC you could want.
Electricity/heating and gasoline in the EU is many times more expensive than in the U.S., and as a result EVERYTHING is more expensive.
Mix that with lower buying power and taxes and we spend 2-3 times for stuff.
I would think that most people would happily choose lower prices over clean energy and paper straws.
Our companies are also less and less competitive because of these initiatives, and companies from China take over in part thanks to the complete lack if environmental and labor laws over there.
Seems to me like this is happening more and more, and it's so widespread and obvious that it almost makes you think that politicians are being bought by Chinese companies/government.
EU electricity prices are high, but attributing this to renewables is backwards. Wholesale electricity prices drop when wind and solar are producing - that's been documented extensively. The high prices are largely due to: (1) gas setting marginal prices during peak hours, (2) grid infrastructure that hasn't kept pace, and (3) taxes/levies that fund the transition. As battery storage grows and reduces gas dependency for peaks, prices should moderate. The countries with the highest renewable penetration (Spain, Portugal) often have lower prices than those still dependent on gas imports.
I'm not attributing to renewables, but green initiatives.
For instance, the rising prices of carbon permits under the EU emissions trading scheme.
So, my point is that countries that don't ignore the economy just to be green--like the U.S. and specially China--seem to have vastly cheaper electricity and gasoline, which I would guess makes them more competitive/lowers prices.
Over here we have no NG and no oil, and on top of that we tax our companies because of emission limits, while in China they burn coal like there is no tomorrow.
We wanted to outlaw non-electric cars, while the car industry in Europe is huge and we don't have a way to build batteries, etc. etc.
> Electricity/heating and gasoline in the EU is many times more expensive than in the U.S.
Maybe because Europe as a whole has little to no signifcant oil reserves ready for extraction? Very much unlike the US.
> I would think that most people would happily choose lower prices over clean energy and paper straws.
The US does have plenty of cheap energy and yet its industrial output is dwarfed by Chinas, which is increasingly relying on domestically products green tech. Also, people seem to be not very concerned with energy prices. If they were, they would not act as irrational when it comes to topics like heatpumps or electric vehicles.
> that it almost makes you think that politicians are being bought by Chinese companies/government.
Looking at the energy policy of some countries (Germany specifically), it seems vastly more likely that politicans are bought by oil companies.
True, there is no oil and we just relied on cheap gas from Russia--which I guess it didn't turn out to be a good strategy after all.
That's interesting about oil companies. Is that who's lobbing to pass laws that just seem (to me) to be written on purpose to make our companies less competitive? How does that work, how do oil companies profit from that?
Yes, and against bike lanes so more people have to drive, and against subsidies for public transport, and against public transport entirely, and so on.
big part is co2 tax. EU now has neptune deep and could explore north sea too. In Germany current transition pathway of ren+gas and no nuclear was defined when Energiewende got introduced with red greens under Schroeder, a gazprom lover and later extended by red blacks
It costs less? The Danish organisation for green energy interest (biased I known) has calculations that shows a 5 billion DKK saving per year for the Danish consumers. So about €0.02 per kWh.
I also think you're wrong about prices. I think most will pay more, if they get clean energy. Not a lot more, but if it's only a few cents, I think many/most will pay that, perhaps not happily, but still. People, in parts of Europe at least, are perhaps more baffled that the Americans won't pay the slightly higher cost and and protect the environment. As it happens that's not a choice we need to make, wind and solar is now cheaper than fossil fuel.
I'm not sure, prices here in Poland have skyrocketed because of the EU green initiative and we started exporting and prices went up 3-4 times.
I'm good with protecting the environment. Here, though, we're making European companies less competitive. They shut down, and Chinese companies fill the gap, flooding us with products that are worse for the environments because they have no laws, bad for workers because they have no laws, and bad for the environment again because instead of local they're shipped across continents on boats that burn as much fuel as a whole country for a year just to bring cheap plastic stuff that we used to make better ourselves.
Arguing that European business should be allowed to pollute the environment more, because that's what China does is a little backwards I think. In my mind we should enforce the rules on a per product basis, rather than per country. Where a product is made shouldn't matter, a product should be taxed based on the pollution it has generated, shipping included.
Want to sell to the EU: Workers can only work e.g. 40 hours a week, must have five weeks of vacation per year and here are the tax rates for various types of pollution.
Imo CO2 tax should be gone to alleviate this, especially when China and US dont have it. This just causes offshoring.
If you want electrification, you need cheap electricity. If you want more ren, you put more incentives there instead of overtaxing fossils to make own industry uncompetitive
But the energy from windmills doesn't have a CO2 tax (it did at some point) and it frequently provides most, if not all, of the Danish energy (electricity) consumption. There's ONE coal fired power plant left in the country and it's scheduled to close in 2028. I get that we then have gas and garbage incinerators for heating, but we are getting electrification and lower prices.
I frankly don't care what the US and China is doing, because they're doing the wrong thing. You're arguing that because you neighbour is throwing trash in the street you want to be able to do the same. I'd much rather make environmental demands of the products being sold to be from else where, and have them live by the same rules, allowing everyone to benefit.
Co2 tax is just an indirect subsidy for renewables. When prices are low those are subsidized through cfds. When high- through merit order artificially pumped by co2 tax. This isn't bad per se but it affects negatively final consumer prices and industry which is bad.
Problem is not about the neighbors throwing trash. Unilateral co2 tax means industry relocates to regions where it's not present. In your analogy it would look like you are sending trash to US to deal with it.
DK is lucky to be able to get firming from nordics, but not everyone can do this. And from what I remember Norway already said one of the interconnectors will not have extended license at EOL
Renewables lead to energy independence and a more distributed energy grid. It's fundamental to security, and can't be so easily measured in terms of money. The EU is increasing its independence from China via initiatives like the Net-Zero Industry Act. And this talk of "politicians being bought by Chinese companies" is laughable in the face of what oil companies are doing, to the benefit of exporters like USA, Russia, Saudi Arabia, and other regimes, and definitively not the EU.
I'm from Poland too and the only thing we have is land, the sun, and wind. Coal poisons the air we breathe, and hurts the climate our children will live in. It's not about money, it's about security. The worst thing for polish security is being dependent on foreign oil and gas, and to be reliant on a few power plants that are an easy target for russian drones, and rely on water from rivers that are running dry more and more often. The transition away from coal should've come much, much sooner. When you hear a push back against renewables, and people praising oil and gas, who's benefiting from this? Poland, or oil suppliers like Russia?
I'm fine with supplementing with nuclear, but it's still a single point of failure, and needs water. France and Switzerland had to shut down nuclear plants last year because the rivers got too hot. This issue is not going away.
Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.
It makes 7.72Mwh per year, worth $1000. Tight valley, tons of snow. We put that on the loan for 8 years, then get $1000 per year free money for 20 years or so. Biggest no brainer of all time.
Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)
Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.
