Nice piece in the New Yorker about how solar is electrifying off-grid Africa.
We can debate how quickly and completely solar and wind will replace coal and gas in the developed world ... but there is no debate about its substantial role in the off-grid developing world. A lot is needed -- financing model, installation in remote areas -- but solar PV + storage has no serious competition in such roles.
"In 2009, a radio, a mobile-phone charger, and a solar system big enough to provide four hours of light and television a day would have cost a Kenyan a thousand dollars; now it’s three hundred and fifty dollars."
