Photovoltaic is not the solution. It's not there yet, but idiots think it's the best. It's made with hazardous materials, except for the really expensive stuff made in the US, takes a ton of space, has a short half life with no feasible way to recycle it. And please don't bitch about least intrusive to the environment like you don't benefit from ecological destructup on and human slavery used to get the materials for lithium batteries, rare earth magnets, and photovoltaic cells.
