Cambridge study puts Ethereum near the lower end of PoS energy intensity
Cambridge estimated that Ethereum consumes 7.87 GWh annually and has the second-lowest market-value-adjusted energy intensity among the PoS networks studied.
A new Cambridge study placed Ethereum near the lower end of energy intensity among major proof-of-stake (PoS) blockchains, although the network still used more electricity overall than most of the PoS networks studied.
The Cambridge Centre for Alternative Finance estimated that Ethereum consumes about 7.87 gigawatt-hours (GWh) of electricity annually. When adjusted for market value, the network used roughly 33 kilowatt-hours (kWh) per $1 million, the second-lowest figure among the proof-of-stake networks assessed, behind BNB Chain.
Solana used the most electricity among the PoS networks studied, at about 13.48 GWh per year. Its energy intensity was roughly 283 kWh per $1 million of market value, around 8.5 times Ethereum’s, while the networks in the comparison consumed about 38 GWh combined.
