This is from the Economist (archived link), one of a June 2024 series on how 'clean energy' is going to change the world and just make everything better. I'm slightly pissed off that I won't be here to live through it! (Also pissed off that I have no money to invest in solar, but them's the breaks.)
In short, solar power's improving and increasing so fast that, by the mid-2030s, it will be the main power source throughout the world and a hell of a lot cheaper than fossil fuels. The ready availability of solar energy will free up creative developments that aren't currently happening because they'd be expensive or difficult.
Even more excitingly, Africa will get rich because it's got a lot of sunshine. This will radically alter world inequalities. The impending cascade of economic migration probably won't happen, because a rich Africa can afford shiny new irrigation systems, transportation, and to keep their people cool & healthy.
It's going to be an age of hope, possibility and incredible achievements.
There are quite a few problems to overcome, the two big ones being that all the solar equipment currently comes from China and we need better systems to store & distribute electricity generated in Africa. Also, the oil producers won't be happy about this and may try to stop it - though they are investing heavily in 'clean' sources, so this could even itself out.
It's all so exciting, though - and cheerful! AIBU to be optimistic for the upcoming generations?
