Solar does not, in fact, require rare earths. (And, incidentally, "rare earths" are very, very far from rare; that is just a name.) And, the cost to clean them once in a while is very low.

You are reaching. The fact is that renewables are the cheapest source of power that has ever happened on this planet, and they are still getting cheaper.

Storage is likewise cheap and very quickly getting much, much cheaper. By the time we actually need any, you will not notice the cost.

You need rare earths for wind power. They broadly come from hellscapes in the far reaches of Mongolia. [1] The reason they're primarily mined in China isn't, as you point out, their not existing anywhere else - it is due to the Chinese being willing to pay the extreme environmental cost of their refining.

The second-most common type of panel, CdTe solar panels still contain cadmium, tellurium and sometimes lead - and all of them to my knowledge have huge quantities of plastic. These are rarely recycled and generally end up buried with the rest of the e-waste in poor countries. [2]

I was talking about solar panels. They are purified silicon… not rare or toxic. You purify it by melting it. The coating of boron or other substance is also not toxic. Compare it to ANY other energy source and it is less toxic in manufacture and of course is completely static in use.

Rare-earth magnets are often used in wind turbines, but very far from always.

CdTe PV is made on glass. They are common mainly in the US, mainly because of import tariffs. But Cd and Te are valuable and easily extracted from panels, so, no, they will not end up in landfills. The Si ones may, but very highly-purified Si is also valuable. Thin-film cells likely to be used in future cells use very little material.

So, you are reaching.

Not reaching, citing.

Your first citation doesn't resolve.

Your second one refers to "black sludge" in Mongolia... but doesn't actually say anything about Solar or Wind production.

Am I missing something?
