Cambridge Study Ranks Ethereum Among Most Energy-Efficient PoS Chains
A Cambridge study estimates Ethereum uses 7.87 GWh annually, ranking it second-lowest in energy intensity among proof-of-stake networks.
A new study from Cambridge researchers has placed Ethereum near the bottom of the energy consumption scale among proof-of-stake blockchain networks, estimating the network draws just 7.87 gigawatt-hours of electricity per year — a figure that underscores how dramatically the platform's environmental footprint has shrunk since abandoning proof-of-work mining.
The research ranked Ethereum second-lowest in market-value-adjusted energy intensity among all the proof-of-stake networks included in the analysis. That metric — which weighs energy consumption against a network's market capitalization — offers a more nuanced view of efficiency than raw consumption figures alone, allowing analysts to compare blockchains of vastly different sizes on a level playing field.

The findings carry significant weight for institutional investors and corporate sustainability teams that have flagged crypto's energy demands as a barrier to adoption. Ethereum's relatively lean consumption profile, validated by a respected academic institution, could bolster the case for its use in enterprise and decentralized finance applications where environmental, social, and governance considerations increasingly drive decisions.
The Cambridge Centre for Alternative Finance has become a benchmark source for cryptocurrency energy data, previously publishing widely cited figures on Bitcoin's electricity use. Applying similar methodology to proof-of-stake networks offers the broader market a standardized framework for evaluating the climate credentials of next-generation blockchains, and Ethereum's placement near the efficient end of that spectrum is likely to feature prominently in future ESG disclosures.
