Those are all made of minerals, except possibly rooftop pipes, which can be made out of plastic.

People are mostly concerned about mining when it comes to REMs (Rare Earth Minerals), not just minerals in general. Many commonplace minerals are not mined but found near the surface or in water. And it’s not just the destructive polluting nature of the mines but also the danger to miners. (For more expensive minerals, I’m guessing the danger will be minimized by using robot miners within a decade).

IMHO, the amount of REMs in solar panels is tiny compared to the amounts used for electronics, power systems, and manufacturing in general. This could be checked.
