This is just objectively untrue. Source: I live in Germany, a country with some of the highest electricity prices, I drive a BEV and I heat my home with a heatpump. My systems SCOP hovers around 3.5, which means that my kWh of heat made from my heatpump with electricity is cheaper than my current gas rate.
My heatpump electricty bill is significantly lower as compared to my apartment (Gas furnace), despite both buildings being roughly comparable late 80s construction.
I charge my car at my standard electrcity rate of 32ct/kWh, and I pay now about half for the same usage.
Electricity is expensive, yeah. But electrified stuff is also significantly more efficient than fossil tech
You pay less vs gas heating because of co2 tax.
And it's just an individual case. Germany's electrification percent is lower vs China's amd the rate of changing is lower too. In other words Germany has more energy used indirectly instead of electricity and electrification percent increase per year is lower than China's too
Amd Germany isn't even the worst example in terms of electricity prices. UK is even worse which will slow it down even more
