And even though many/most people still consider it fringe, there is strong evidence supporting the abiogenic oil theories. Which would mean oil, or at least some of it, is also not derived from the sun. Same goes for coal. Some is clearly derived from plant matter, as such the energy came from the sun, and some is mineral in origin, meaning it was formed from geologic processes.Once we have developed a means of converting photons to electricity that does not require massive amounts of rare earth materials, and we solve storage related problems, then I would agree solar is the way to go in the long run.</blockquote>
