Ethereum (ETH) has achieved a massive reduction in energy consumption, with its annual electricity usage now recorded at just 7.87 GWh. This figure is less than 50% of the energy consumed annually by the British Museum. This significant decline is attributed to the network's transition from the Proof-of-Work (PoW) consensus mechanism to the Proof-of-Stake (PoS) system, an event widely known as The Merge.
A Dramatic Shift in Efficiency
Researchers conducted an audit of approximately 8,522 full nodes that process and store data on the network. The study highlights that the network's energy demand has dropped by 99.9% since the transition. The report illustrates the magnitude of this change by stating that if Ethereum's pre-Merge energy consumption were represented by the height of the Statue of Liberty, the post-Merge network would be comparable to a small golf ball resting at its base. For years, Ethereum relied on the resource-heavy PoW model, drawing significant criticism. The switch to PoS in September 2022 fundamentally altered how the network maintains its security and validates transactions.
Security and Operational Costs
The research emphasizes that while PoW required massive electricity expenditure to reach consensus, PoS security is collateralized by staked capital. Consequently, electricity consumption is now merely the operational cost associated with the participating node population. Geographically, 62% of Ethereum's full nodes are located in the United States (31%), Germany (16%), Finland (8%), and France (6%). The power mix fueling these nodes currently consists of 56.4% sustainable energy and 43.6% fossil fuels.
Carbon Footprint Reduction
The network's annual carbon footprint is now 2.37 ktCO₂e, marking a 99.98% decrease from pre-Merge levels. This is roughly equivalent to the combined carbon footprint of 900 UK households. Experts note that even if electricity consumption levels remain flat, the network's total carbon emissions are expected to decline further as the power grids fueling the full nodes continue to decarbonize.
Technical Outlook for ETH
As of the latest market data, ETH-USD is trading at $1,793, up 2.79% from the previous close. On the daily chart, the price is testing the 50-day SMA at $1,773 and the 50-day EMA at $1,799. The 14-day RSI sits at 57, suggesting constructive momentum. While the MACD is currently showing a bullish signal, the asset remains in a long-term downtrend. The 20-day EMA at $1,723 provides immediate support. Traders are watching overhead resistance levels at $1,820 (R1) and $1,847 (R2), while structural support floors are established at $1,752 (S1) and $1,710 (S2). With the stochastic indicator at 87, price recovery attempts may face intermittent profit-taking near these technical barriers.
