- In September 2024, wind energy was the primary source of Britain’s electricity generation, accounting for 26% of the energy mix, which was its highest contribution for September in the past four years. Gas was the second most prominent source, making up a quarter of the mix, marking its lowest contribution in the past four years and an 8% decrease compared to its contribution in September of the previous year.
- Nuclear power supplied 16% of Britain’s electricity, which was 1% lower than its contribution in September of the previous year.
- Both biomass and imports saw a 4% increase in their proportions in Britain’s electricity mix, with biomass contributing 8% and imports delivering 15%, marking the highest contributions of their respective fuel types in the past four years.
- Coal made its lowest contribution for September in the past four years, accounting for less than 1% of Britain’s electricity mix.
- Hydro and storage maintained consistent contributions compared to September of the previous year, making up 2% and 1% of the mix, respectively.
- Zero carbon sources contributed to half of Britain’s electricity in September 2024, marking its highest contribution for September in the past four years and a 1% increase compared to its contribution in September of the previous year. This led to the lowest carbon intensity for September in the past four years, with a 23% decrease compared to the carbon intensity for September 2023. Furthermore, the rolling 12-month average carbon intensity of 123 CO₂/kWh is currently 22% lower than the previous 12-month period, remaining the lowest of the past four years as the grid continues to decarbonise.
- Increasing the electricity generation from renewable sources can help achieve our net-zero ambitions, ensure energy security, and decrease reliance on imports.
