According to a new study by Cambridge University, more than half of the energy used for Bitcoin mining now comes from green sources.

The Cambridge Centre for Alternative Finance (CCAF) published a report stating that 52.4% of the electricity consumed by Bitcoin miners comes from sustainable sources, including renewable and nuclear energy.

The report details that 9.8% of the energy used for Bitcoin mining comes from nuclear power plants, while 42.6% comes from renewable sources, including:

  • hydroelectric power — 23.4%;
  • wind power — 15.4%;
  • solar power — 3.2%.

Meanwhile, energy from coal combustion used in Bitcoin mining makes up just 8.9% in 2025, a significant drop from 36.6% in 2022. Additionally, energy from natural gas increased to 38.2%, rising by almost 15 percentage points over the past three years.

The study is based on a survey of 49 mining companies from 23 countries, representing approximately 48% of Bitcoin’s total hash rate. Among the survey participants were Bitfarms, CleanSpark, Hut 8, IREN, MARA, and Riot.

Notably, Cambridge analysts report a significant increase in the use of green energy for Bitcoin mining compared to 2022, when the share of sustainable energy in Bitcoin mining was 37.6%. Furthermore, a report by the Bitcoin Mining Council (BMC) in the same year showed that the mining industry demonstrated high resilience in its energy balance — in Q2 2022, 59.5% of the electricity used for BTC mining came from renewable sources. Scientists from universities in the Netherlands and the U.S. consider around 75% of existing studies on Bitcoin’s energy consumption to be unreliable, which could explain discrepancies in the statistics.

The industry is also increasingly focused on integrating sustainability principles. For example, the importance of the ESG (environmental, social, and governance) approach in the cryptocurrency industry was highlighted by Violaine Champetier de Ribes, ESG Officer at CoinsPaid. “Our ESG policy is the first step of our strategic roadmap meant to gradually integrate sustainability into our core operations while fostering trust among users, partners, and regulators. Responsible crypto payments aren’t just possible — they’re essential for long-term industry growth,” claims Violaine.
