Ethereum's Proof-of-Stake Energy Use Ranked Among Lowest by Cambridge

A recent study by Cambridge's Centre for Alternative Finance has found that Ethereum's proof-of-stake energy use is at the lower end among major proof-of-stake blockchains.

The researchers estimated that Ethereum uses about 7.87 gigawatt-hours (GWh) of electricity annually, which translates to around 33 kilowatt-hours (kWh) per $1 million in economic-adjusted terms.

This puts Ethereum near the bottom of the proof-of-stake set measured by Cambridge, with BNB Chain being the only network that uses less energy per unit of market value.

Solana, on the other hand, was found to be one of the most energy-intensive networks among those studied, consuming around 13.48 GWh per year and having an energy intensity of about 283 kWh per $1 million.
