But what proportion of the cost of a solar panel is actually made up of rare earth minerals or labour? My understanding was that the cost of installation dominated the cost of manufacture for both wind and solar. And, sure, plenty of rare earths are needed both for the drivetrains in wind turbines, and for the power electronics used by solar farms. But they'll also be needed for the steam turbines and power electronics in nuclear plants. Seems like it's pretty much a wash to me. I don't have a dog in this fight, but it seems deeply weird for America to be refusing to even try to meet the challenge.
