A new report from the Cambridge Centre for Alternative Finance estimates Ethereum now uses about 7.87 GWh of electricity per year, down more than 99.9% since The Merge. The report also estimates annual carbon emissions have fallen by about 99.98%. The findings highlight the network’s significantly lower environmental impact following its transition to proof-of-stake. Researchers said Ethereum’s environmental footprint now depends mainly on the carbon intensity of local power grids rather than its consensus mechanism.
