So where does the electricity for EVs come from? One source is solar energy. Well, in fact, that’s the only source - all energy on this planet is originated by the sun’s nuclear reaction (other than nuclear reactors we build here, but we need the sun’s energy to build those too, and look at Chernobyl and Fukushima for how that can end). Most fossil fuel - oil, coal, most "natural gas" - is hundred-million-year-old photosynthesis products that we dig up and burn.
