Crypto mining needs cheap energy, and household and nuclear electricity is anything but.
If anything, it helps suppliers monetize the load which would otherwise be wasted, like unexpected peaks in solar or wind production.
IF it happened that crypto mining drives electricity prices up, the economy would reach a new balance with mining included.
In any case, crypto mining pays carbon tax as any other industry. If I get sound money in exchange, I agree to pay the transaction fees, which will in turn offset those expenses.
There are cryptocurrencies that do not need more power than any other kind of computing because they do not rely on proof-of-work. Proof of work is a waste at any price. Better to use low cost renewable power for synfuels for aviation or other high value applications.
One point of proof-of-work is to allow chain continuity in the event of a network split.
You can easily tell which chain has the most work sacrificed, but if a netsplit occurs with a proof-of-stake protocol, it is vulnerable to a Sybil attack hijacking consensus with, say, a botnet.
