  Indeed, Wikipedia: Proof of stake # Energy consumption

  In 2021, a study by the University of London found that in general the energy consumption of the proof-of-work based Bitcoin was about a thousand times higher than that of the highest consuming proof-of-stake system that was studied even under the most favorable conditions and that most proof of stake systems cause less energy consumption in most configurations.

  In January 2022, Erik Thedéen, the vice-chair of the European Securities and Markets Authority, called on the EU to ban the PoW model in favor of PoS because of the latter’s lower energy consumption.

  Ethereum’s switch to proof-of-stake was estimated to have cut its energy use by 99%.
