Proof-of-work works fine with clean energy. You should direct your concerns at polluting forms of energy sources.
Increased energy usage is increased energy usage. The underlying argument here is proof of working isn't actually burning this energy for any useful purpose and the excess clean energy production should be directly offsetting dirty energy production instead.
If you have already mined coal burning in a field and instead take that coal and put it through a generator and mine bitcoin with it you are using more energy and cleaning up emissions. https://www.wesa.fm/environment-energy/2022-01-31/how-waste-...
In a lot of places in the midwest up to 25% of wind or solar energy is priced at a negative level, this means they are paying to produce energy. Setting up a bitcoin miner is perfect because it can be quickly turned on/off and doesn't require consistent power like most manufacturing or other energy intense activities. This makes renewables more economical.
This goes into all of this as well. https://niccarter.info/wp-content/uploads/txsummit_nc_oct08....
