I haven’t looked too deeply at it yet - but I don’t think it would lead to more excessive energy costs than PoW. It’s using PoS in addition to their PoH validation algorithm; and you have to “stake” or lock some amount of tokens up in order to validate and earn rewards. So you wouldn’t simply be able to spin up hundreds of validators (GPUs) because you’d quickly have no funds left to stake.
