Ethereum uses less power than British Museum – Here’s what changed
Ethereum's transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in "The Merge" has drastically reduced its energy consumption. The network now uses approximately 7.87 GWh of electricity annually, less than half the British Museum's usage, marking a reduction of over 99.9% from pre-Merge levels. This has also cut its carbon footprint by 99.98% to an estimated 2.37 kilotonnes of CO2 equivalent per year, comparable to the emissions of about 900 UK households.
The Cambridge Centre for Alternative Finance (CCAF) reports that Ethereum's infrastructure remains decentralized, though geographically concentrated, with 62% of nodes hosted in the US, Germany, Finland, and France. About 56.4% of its electricity comes from sustainable sources, primarily nuclear and renewables, exceeding the global average.
Future developments like stateless verification may further reduce energy needs. Meanwhile, Ethereum's development enters a new phase with "Lean Ethereum," a multi-year overhaul plan for the network's evolution. At the time of reporting, ETH's price saw a slight increase, trading near $1,800.
