Summary

The UK’s electricity in 2024 was the cleanest on record, with 58% generated from low-carbon sources, including wind, solar, and nuclear.

Renewables alone supplied a record 45%, while fossil fuels, including gas and coal, still accounted for 29%.

Carbon Brief’s analysis highlights a significant drop in carbon intensity, with emissions per kilowatt-hour falling by over two-thirds since 2014.

The Labour government aims to fully decarbonize electricity by 2030, but experts warn achieving a 95% low-carbon grid leaves little room for error.

Wind is expected to overtake gas as the top power source by 2025.
