That's the big environmental issue with Bitcoin — other major cryptocurrencies have moved to proof-of-stake instead of proof-of-work, so they don't need vast quantities of energy, and when you stop using all that energy, the generators with the highest marginal cost shut down, which generally means coal or gas.
A few months ago I read up on how much energy is used in a bitcoin transaction compared to a VISA transaction, it was something like 10000 times more energy for a bitcoin transaction
