Okay, so #WindTurbines (their generators mostly, to be precise) contain #RareEarth elements. Those aren't actually rare, by the way. But at the moment they are strategically rare because a certain #West didn't bother for decades and a certain #China almost monopolised the market (tough shit, but manageable).
Now, there's also an ecological question to #mining (and hopefully some day #recycling - we suck at this) these elements. And right now, German press seems to go a little crazy about this.

But you know what? Lignite (brown #coal), black coal, #oil and #NaturalGas are - right now - being mined at enormous ecological expenses. They aren't building materials that you need once (few hundred kg per installed MW) but fuel (of which you need tons per MWh produced). And literally nobody seems to care.

I've got to say: As a society we royally suck at having informed discussions about technology and, well, our future as a civilisation.
