A new study from the Cambridge Centre for Alternative Finance has assessed Ethereum’s energy consumption, revealing that the network consumes approximately 7.87 gigawatt-hours (GWh) annually. This positions Ethereum as having the second-lowest market-value-adjusted energy intensity among the proof-of-stake (PoS) networks analyzed.
Energy Consumption Insights
Despite its relatively low energy intensity, Ethereum’s overall electricity usage remains higher than many of its PoS counterparts. The study indicates that Ethereum’s energy intensity is about 33 kilowatt-hours (kWh) per $1 million in market value, trailing only behind BNB Chain in the rankings. In contrast, Solana topped the list with an annual consumption of around 13.48 GWh and an energy intensity of approximately 283 kWh per $1 million, which is about 8.5 times that of Ethereum.
Methodology and Findings
The Cambridge study provides a comprehensive analysis of Ethereum’s energy footprint following its transition to proof-of-stake validation in September 2022, known as the Merge. This transition eliminated the energy-intensive mining process, resulting in a reported reduction of over 99.9% in electricity usage. The study measured the power consumption of Ethereum nodes across various setups, finding that typical home configurations used around 18 watts, while more robust workstations consumed about 153 watts. The average power draw across Ethereum’s nodes was estimated at 105 watts.
Node Distribution and Energy Sources
According to the study, there are approximately 8,522 discoverable full nodes on the Ethereum network, with 64% operating in cloud or enterprise facilities and 36% on residential connections. The remaining emissions from Ethereum are largely influenced by the electricity grids that supply power to these nodes. Notably, the study found that around 56.4% of Ethereum’s electricity mix comes from renewable and nuclear sources, while 43.6% is derived from fossil fuels.
Implications for Stakeholders
This detailed assessment of Ethereum’s energy use offers valuable insights for policymakers and investors, providing a clearer framework for evaluating blockchain sustainability. As the cryptocurrency landscape evolves, understanding the energy dynamics of major networks like Ethereum will be crucial for future regulatory considerations and investment strategies.
