Ethereum’s transition to Proof-of-Stake has reduced its annual electricity consumption by over 99.9%, from 2.4 GW to 0.90 MW – less than half the British Museum’s usage. The network now consumes 7.87 GWh with 8,522 physical nodes and nearly 894,000 validators. A CCAF report found 62% of nodes are concentrated in four countries, and 56.4% of electricity comes from sustainable sources. Carbon emissions fell 99.98% to 2.37 ktCO₂e annually. Developers unveiled a multi-year “Lean Ethereum” overhaul. ETH traded at $1,798.71, up 1.42%.
After migrating to Proof-of-Stake, Ethereum now operates with 8,522 physical nodes and nearly 894,000 validators. The network consumes just 7.87 GWh of electricity annually, equivalent to 0.90 MW of continuous power – less than half the British Museum’s usage and a reduction of over 99.9% from the pre-Merge requirement of 2.4 GW.
A report from the Cambridge Centre for Alternative Finance (CCAF) found that 62% of all nodes are concentrated in four countries: the United States (31%), Germany (16%), Finland (8%), and France (6%). Of the electricity powering Ethereum, 56.4% comes from sustainable sources, including 17% nuclear and 39.4% renewable energy – above the global average of 43%.
Natural gas remains the largest fossil fuel source at 27.7%. Ethereum’s carbon footprint has dropped to an estimated 2.37 kilotonnes of CO₂ equivalent per year, a 99.98% reduction from its final Proof-of-Work era and comparable to the annual emissions of roughly 900 UK households.
Future developments such as stateless verification may further reduce energy and hardware needs. Developers have also unveiled “Lean Ethereum,” a multi-year plan to replace core protocol components over three to four years.
At press time, Ethereum was trading at $1,798.71, up 1.42% in the previous day. The MACD and RSI indicators suggest bulls are more aggressive than before, though ETH needs to surpass the $1.8k mark to maintain upward momentum.
