More than 73% of electricity generated in Great Britain in 2024 came from low-carbon sources, marking a significant rise from 68% in 2023, according to new government figures released on Monday.
The data, published in the Department for Energy Security and Net Zero’s latest Energy Trends report, represents the first official progress update toward the UK’s target of reaching 95% clean electricity by 2030.
The report highlights record levels of renewable generation in the second quarter of 2025, with renewables accounting for 54.5% of total electricity generation across the UK. This is up from 51.7% during the same period in 2024.
Offshore wind and solar power contributed significantly to the increase. Offshore wind output rose by 10%, while solar generation grew by 27%, driven by additional capacity and higher sunshine hours.
Low-carbon sources—including wind, solar, nuclear, and hydro—reached a quarterly record of 69.8% of total generation. In contrast, electricity generated from fossil fuels dropped to an all-time low of 26.7%. For the third time on record, wind power surpassed gas in quarterly generation.
“This shows that Britain is making excellent progress towards clean power by 2030,” said Barnaby Wharton, director of future electricity systems at RenewableUK. “We’re rolling out vital new wind and solar projects, strengthening our capacity to generate secure homegrown power.”
He added that expanding renewable infrastructure could also have broader economic benefits. “This will insulate bill payers in the long term against the volatility of international gas prices which caused the energy crisis,” Wharton said. “We now have 2,000 supply chain companies based in 70 constituencies all over the UK.”
The report reflects ongoing efforts by the UK government and industry to accelerate the energy transition and reduce reliance on fossil fuels, aligning with broader net-zero targets.
