You switch to a coin that uses proof-of-stake? Several of the totally OG cryptographers, like Chaum or Micali, have created blockchains that are using PoS (Micali is behind Algorand and Chaum behind an upcoming "elixxir" coin I think, forgot the name). Of course there's also Ethereum which is currently switching to PoS. Cryptocurrencies haters better find another argument than "energy consumption" because I think the gigantic energy waste is coming to an end soon.
