Cambridge Report Confirms 99.98% Drop in Ethereum Energy Use Post-Merge

Key Facts

In a move that strengthens the appeal of digital assets for ESG-conscious institutions, a new report from the University of Cambridge reveals that Ethereum's transition to proof-of-stake reduced energy consumption by 99.98%. The Cambridge Centre for Alternative Finance confirmed that the upgrade, known as 'The Merge,' successfully scaled down the network's power requirements from levels comparable to small nations to negligible amounts. This report provides critical academic validation for the technical success of the network's sustainability goals.

These findings place Ethereum in a favorable position relative to Bitcoin, which continues to rely on energy-intensive proof-of-work mining; prior estimates from the Cambridge Bitcoin Electricity Consumption Index (CBECI) suggest Bitcoin mining exceeds 120 TWh annually. Per market data, this radical shift in the sustainability profile enhances the prospects for ESG-focused Exchange Traded Funds (ETFs), potentially unlocking new institutional liquidity flows that previously avoided the sector due to environmental concerns.

Investors are now looking toward macroeconomic catalysts that could influence risk appetite. Key events to watch include the speech by Fed Governor Waller scheduled for later today, July 6, 2026, which may provide signals regarding liquidity trends and their subsequent impact on alternative asset classes.
