An alternative perspective is that crypto mining should be required to only use main-grid surplus or their own renewable energy sources. Then make it hideously expensive for them to not use renewables. This way the bitcoin / cryptos would be for public good. They'd be incentivised to improve the world situation rather than be a burden.
But governments are usually really bad at this sort of thing and they'd probably just mess it all up. It would likely involve a messed up website, multiple privacy violations, various forms of messed up bureaucratic red tape and all sorts of other anti-patterns.
Also, incentives being incentives, forcing crypto miners to use, eg solar, would likely just spike the prices of renewables and cause other issues.

Ok, I'm outta ideas.
