Not all crypto is hard to mine you know. Stuff like Ethereum and Solana don't use up that much electricity bc they use a different method called proof of stake, rather than bitcoins proof of work. Basically people who wanna validate transactions stake some money on the network, and if they validate a transaction right, they get paid a bit. If they get it wrong, they lose that money they staked. And the more money they stake, the more they make from validating transactions.
