- In February 2025, gas accounted for 33% of Britain’s electricity mix, making it the largest contributor, slightly ahead of wind energy, which supplied 32%. This marks a 6% increase in gas-generated electricity and a 3% decline in wind energy compared to February 2024. The highest-ever wind energy contribution for February was recorded in 2022, when it made up 40% of Britain's electricity mix.
- Solar, biomass, and storage delivered the same contributions as in February 2024, contributing 2%, 7% and 1% respectively.
- Nuclear energy saw a 1% increase, supplying 12% of Britain's electricity in February 2025 - its highest share for February in the past three years. However, this remains 2% below the levels recorded in February 2021 and 2022.
- Hydro contributed 2% of Britain’s electricity generation, a 1% decrease from its 3% share in February 2024.
- Coal, which was phased out of UK electricity generation in September 2024, contributed 0% in February 2025. For comparison, coal accounted for 1% of electricity generation in February 2024.
- Zero-carbon sources delivered 48% of Britain’s electricity in February 2025, 3% lower than in February 2024 and the third highest for February in the last five years. However, the rolling 12-month average for zero-carbon electricity remains at 50%, the highest of the past five years.
- The carbon intensity of electricity generation in February 2025 was 147 gCO₂/kWh, 11% higher than in February 2024 and the third highest of the last five years. Despite this, the rolling 12-month average carbon intensity stands at 126 gCO₂/kWh, the lowest in five years and 17% lower than the previous 12-month period.
- Increasing renewable electricity generation remains crucial to achieving net-zero goals, enhancing energy security, and reducing reliance on imports.
