i love that in a lot of countries people think these other countries are in the sticks and that they are modern... (ofc depending who u talk to but im sure we all know such a person...) :) a lot of perceptions based on old world views. Love to see these countries do so well on it. There might be many problems to solve still but it provides a degree of self reliance for energy that is really important today for a country i'd think
It's contrary to what most people think, but the later a country modernized, the better the infrastructure (generally). You basically get to skip the innovation stages where you have a hodgepodge of systems that eventually coalesce into one and all the upgrading required to bring it up to the newest standard. If you have a lower population and smaller geography, it is often easier to upgrade as well.
DR Kongo: 98% Hydropower, $ 760 GDP/person , 13% of country has electricity
Not sure how this is applicable (and in many cases: desirable) for countries that do not have significant hydropower potential or maybe want a GDP greater than $760 per person per year.
On the other hand, balcony solar power will be a game changer for the world, provided your neighbors won't steal the panels like they do the catalytic converters in my neighborhood.
