Solar power is key. Let me know what you find out about it in your research. I have always felt that solar power will be especially valuable in Africa because (a) it relies on the sun, which is plentiful and (b) it is completely decentralized and lends itself well to remote areas or areas of sparse settlement. Everyone always says solar power is not cheap enough to be pratical yet, but I don't know specifics. It's environmental footprint is basically nothing as well.
