No, I'm not arguing that Westerners should adopt solar as a form of aid for Africa. I don't see how you could have concluded that from what I said.

And narrowly measuring "cheap" in cost per kwh does not address my point - that the up-front cost to get power at all is far cheaper for solar/wind + storage. A village is not a city. It doesn't need a gigantic power plant, and can't afford one. Look at it this way - I could buy myself a can of soda for a buck, or I could buy a bottling plant for a million bucks. In terms of cost-per-liter, the bottling plant is a huge bargain. But I don't need a bottling plant! It's actually useless to me. A can of soda? That's useful, and scaled correctly for my budget and needs.

I don't think this is hard to understand.
