If you are going to do PoW the least harmful way is inherently CPU algorithms like Monero’s RandomX. At least the left over parts have an aftermarket use as CPUs, and at least you are incentivizing production of something useful. It can even run as a lowest priority process with other compute in some cases.

Note that Chia’s form of proof of space does not count since it actually consumes SSDs. CPUs are not (meaningfully) consumed by running RandomX.

(CPUs at dense process nodes do degrade slowly but their life spans are usually far longer than their useful life anywhere in the market.)

Or you do something like "proof of useful work" as discussed in https://eprint.iacr.org/2017/203.pdf

I think we need a way better (re)use of the heat generated by the hardware instead cooling it or placing the hardware in cool places.

This reminds me of that tweet from BP about their environment calculator, can't find the source right now. But the idea is they "care" about environment while they did the biggest oil spillage in history, otherwise known as the old proverbial: https://en.wikipedia.org/wiki/The_pot_calling_the_kettle_bla...

Do I really need to point who is the biggest e-waste generator in the world? Solve that problem first.

isn't that somewhat against the whole idea of PoW? It is supposed to make cheating expensive, because you have to waste a lot of computing power to do it. If that power is not wasted, but instead used for something useful (outside of crypto transaction verification) work that can be sold for money, then cheating becomes profitable again.
