Bitcoin mining is supporting  so called Green energy projects the capital to continue operations, stabilisers the grid by buying excess energy they generate, keep the costs down of  necessarily idling hydrocarbon energy producers that necessarily support those intermittent producers, turn escaped methane gas at well heads into "less damaging" gases, should you believe in that fanciful propaganda, capitalise stranded hydropower for poor villages  to have constant cheap electricity, bank the unbamked and give them access to globall liquidity (which sorry none of yiur other coins comes close to matching, incl eth)

I could go on.

 TLDR it's the opposite of what you believe 

 Would like to learn more about this. Can you point me to some reliable sources for reading/research? I found this recent-ish (24 October 2023) report published by the United Nations University (a reliable source, yes?) that talks about the environmental damage of cryptocurrency in general and bitcoin in particular, since it's the most popular. https://unu.edu/press-release/un-study-reveals-hidden-environmental-impacts-bitcoin-carbon-not-only-harmful-product

Alex gladstien has quite a few things on this topic although he primarily focuses on BTC and human rights, energy and BTC is part of that

there's crap loads out there, but it will get you started

don't forget El Salvador using volcanic energy to mine, which feeds back capital to grow the countries energy infrastructure 

No the UN are one of the last groups with educated opinions: they're an ossified institution with the incentive to maintain the status quo
