Then why not stop producing it, instead of using it on Bitcoin? Even 'clean' energy production has environmental costs, from environment destruction for hydro to maintenance/production costs for solar and wind.
Excess electricity can be a real problem, and is getting worse with renewables. But surplus energy would be better used to desalinate seawater, or produce hydrogen through electrolysis, or storage.
Or with electrolysis or storage you need to generate it and transport it to where it can be used, getting you back to square one because nobody is doing that because it is uneconomical. Whereas mining is not because it can be all done on site in remote locations and doesn't even need great internet. High latency, spotty internet is good enough for crypto mining.
We know what the ideals are: no pollution and infinite energy, or no pollution and less energy use. Thats not going to happen, and crypto wasn’t part of those 50 year old models, yet it is accomplishing a lot of those ideals and people choose not to respect its existence as it alters their worldview.
