Bitcoin? Yes, it's a useless coin. I wouldn't mind even higher amounts of energy being spent on Monero though.
It's good that Ethereum is moving to proof of stake. Not because of some environmental impact though. Mining is just really expensive, it results in huge fees making the coin almost unusable for normal people.
