New Cambridge Study Ranks Ethereum’s Energy Efficiency in PoS Chains
In Brief: A recent Cambridge University report revealed that Ethereum ranked among the least energy-intensive proof-of-stake blockchains, yet consumed more electricity overall compared to other PoS networks.
Main Developments
The Cambridge Centre for Alternative Finance estimated that Ethereum consumes 7.87 GWh annually, with an energy intensity of roughly 33 kWh per $1 million of market value. The post-merge transition in September 2022 drastically reduced Ethereum’s energy consumption by 99.96%, shifting from a PoW to a PoS consensus mechanism.
Why This Matters
This study offers valuable insights into Ethereum’s energy footprint post-merge, enabling policymakers and investors to assess blockchain sustainability amid increasing environmental concerns.
Market Context
The report highlighted Solana as the most electricity-intensive network, using around 13.48 GWh per year and 283 kWh per $1 million market value. Ethereum’s transition to PoS significantly decreased its energy consumption, positioning it as a more eco-friendly option among PoS chains.
Conclusion
Cambridge University’s study sheds light on Ethereum’s energy efficiency compared to other PoS blockchains, emphasizing the network’s progress towards a more sustainable future.
FAQ
How did the September 2022 merge impact Ethereum’s energy consumption?
The transition to a PoS consensus mechanism during the merge reduced Ethereum’s energy consumption by approximately 99.96%, significantly lowering its environmental impact.
What are the key findings from the Cambridge study regarding Ethereum’s energy use?
The study revealed that Ethereum consumes 7.87 GWh annually, ranking it among the lower end of energy intensity among major PoS blockchains, while still utilizing more electricity overall compared to most PoS networks.
