Cambridge study puts Ethereum near lower end of PoS energy intensity
A Cambridge study estimated that Ethereum currently consumes about 7.87 GWh of electricity annually, placing it near the lower end of energy intensity among major proof-of-stake (PoS) blockchains. Adjusted for market value, Ethereum uses approximately 33 kWh per $1 million, second only to BNB Chain, while Solana consumes the most at 13.48 GWh annually with an energy intensity of 283 kWh per $1 million. The study also noted that 56.4% of Ethereum’s electricity comes from renewable and nuclear sources, with the network’s energy use significantly reduced following its transition from proof-of-work to proof-of-stake after the 2022 Merge.
