What are good charities for donating to electrification and clean energy in developing countries? What are current innovations in the field?
Just one example, there is evidence that clean cooking stoves can reduce air pollution in the home and uplift status of women (who travel long distances for several hours, more exposed to dehydration and sexual violence).
There are two orgs that recommend effective charities for climate change in general:
Founders Pledge focuses on the "triple challenge" of climate change, air pollution, and energy poverty. If you're interested in donating to address both climate change and energy poverty, I recommend giving to the FP Climate Change Fund or FP's recommended climate charities. This includes CATF, which Karthik recommended, but also other organizations like TerraPraxis and Future Cleantech Architects.
