Monero uses RandomX which must be done only on CPU which limits power consumption drastically and promotes decentralization rather than mining farms like bitcoin. Both of those combined will make it much easier for utilities to handle it. Since one utility won't be getting hit with extreme load from mining farms all in one single area, such as Texas. You've also got to consider how much electricity does the banking industry as a whole use for building their buildings, bringing employees to work, shuttling money around in armored trucks, all that stuff. There's probably tons I'm not even thinking of. Proof of work is better than proof of stake simply because a governmyth can't print more of their crap fiat currency and buy up more stake in order to hurt the network. If a government wants to attack Ethereum, they just print more fiat currency and buy Ethereum. If they want to attack Bitcoin or Monero, they have to buy the equipment to do so and then plug it in and use power. They would have to sacrifice something real in order to do that.
