The Merge brings down Ethereum’s network power consumption by over 99.9%

Before the Merge upgrade, in 2022, the energy consumption of Ethereum ranged between 46.31 terawatt hour (TWh) per year to 93.98 TWh per year. The lowest energy consumption for Ethereum was recorded on Dec. 26, 2019, at 4.75 TWh per year.

Starting from Oct. 15, the day of the Ethereum Merge, Ethereum’s energy dropped down by over 99.9%. When translated to single Ethereum transactions, the electrical consumption is as low as 0.03-kilowatt hour (kWh) and the carbon footprint stands at 0.01 kgCO2, which is equivalent to the energy used when watching two hours of YouTube.
