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.

Or you do something like "proof of useful work" as discussed in https://eprint.iacr.org/2017/203.pdf
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.
I could imagine the RandomX code execution approach being re-worked to incorporate useful scientific computation, and this being worked into the currency itself. It might be possible for people to stake money on compute units and then have the money go to the miner who solves a block in proportion to compute units performed. You'd have to put a lot of work into making this non-gameable though.
Maybe something can be done here with homomorphic encryption too, so the miners would not even know what they are computing.
A lot of interesting open cryptography and math work here.
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 (meaningfu…
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.
Most industrial processes require heat beyond what a mining chip could handle... unless you fabricated special mining chips out of different semiconductor materials that can handle high heat. But that's probably too expensive for the economics to work too.
What would make some sense to me is an integrated solar PV panel / mining unit. Just deploy them in the desert and connect them. Each panel could be discrete and WiFi connected, meaning you would not have to wire them to anything at all. Just prop them up in the sun with WAPs every so often to connect them to a network.
I'm starting to get irate now with the hypocrisy of some who talk about how the Government need to be more green, but then follow up with "oh my bitcoin worth's gone through the roof!"
Are there any similar studies regarding the banking system?
With buildings and buildings full of offices just for banks, their IT infrastructure, plus ATMs, POS, etc.
How frequently are these systems replaced/upgraded?
How much energy are they using?
I think it would be interesting to make a comparison.

Vehicles i.E. cars?
They will still be washing up on beaches 100 years after every single person involved in their design has passed.
Whole electronics industry needs to take this stuff more seriously, we need more replaceable batteries and storage, right to repair on a global level and laws against the sort of thing Apple does with their repair pricing where the repair costs like $50-100 less than a new device.

Oh you mean like those people who fly around in private jets while admonishing people for inter alia flying on commercial airliners too much? (Remember: you're just a peasant. Money elevates you into a new ontic reality where the normal moral principles don't apply.)
You get a bunch of normal people (i.e. 'peasants' if you wish) sitting around talking about how to save the environment while eating fruit grown in a faraway land and trucked to them in a refrigerated truck.
Everyone wants to say the solution is that other people should change the way they do things, not themselves.
