Interesting that some here complain about rare earths in renewable power generation, when:
As of today, June 8, 2024, here's an estimate of the market values of the catalyst metals in an average cat converter:
Platinum (Pt): 7 grams x $31.08 per gram (price per gram can vary) = approximately $217.56
Palladium (Pd): 7 grams x $29.68 per gram (price per gram can vary) = approximately $207.76
Rhodium (Rh): 2 grams x $145.48 per gram (price per gram can vary) = approximately $290.96
Hmmmm, the REAL Players in common solar panels are:
Silicon, indium, gallium, selenium, cadmium, and tellurium. These are sometimes referred to as rare metals, but they're not classified as true rare earth elements.
