Report: Bitcoin's annual electricity consumption reaches 138 TWh, with 52.4% coming from sustainable energy
ChainCatcher News, the latest "Cambridge Digital Mining Industry Report 2025" shows that Bitcoin's current annual electricity consumption is estimated at 138 TWh, generating approximately 39.8 Mt of CO2 equivalent emissions.
The report points out that currently 52.4% of Bitcoin mining energy comes from sustainable sources such as renewable energy and nuclear power. In contrast, Ethereum, after completing the "Merge" upgrade in September 2022 and transitioning from Proof of Work (PoW) to Proof of Stake (PoS), has reduced its energy consumption by about 99.9%. Experts state that the environmental impact of Bitcoin mining goes beyond mere electricity consumption, also including carbon emissions, water resource consumption, land use, and electronic waste. With increasing policy pressure, governments are paying more attention to the types of energy used in mining, their locations, and their external impacts.
