​Almost three quarters of Britain's electricity last year came from clean power sources, according to figures published by the Department for Energy Security and Net Zero.

According to the government's latest Energy Trends report, renewable sources and nuclear energy together provided 73.8% of Great Britain's electricity supply in 2024. This marks a rise from the 2023 figure of 68.3% and represents the strongest indication so far of progress towards the government's target of achieving 95% clean power by 2030.

The report also highlights a strong performance in renewable generation during the spring and early summer months. Between April and June 2025, renewables produced 54.5% of the UK's electricity, setting a new quarterly record. This was up from 51.7% in the same period the previous year.

Offshore wind generation rose by 10% while solar output climbed by 27%, helped by the addition of new capacity as well as record sunshine hours. Overall, low-carbon sources accounted for 69.8% of electricity in the second quarter of the year, beating the previous high of 69.3% recorded in 2024.

At the same time, fossil fuel use fell to its lowest level on record at 26.7%. Wind generation exceeded gas for the third time in a quarterly period, underlining the scale of the shift in Britain's energy system.

Industry figures described the results as evidence of the country's continuing transition away from fossil fuels and towards secure, homegrown clean energy. They noted that the expansion of wind and solar capacity is not only increasing the resilience of the power system but also supporting thousands of jobs across the UK, with supply chain companies operating in dozens of constituencies.

The publication of these statistics marks the first time the government has reported official progress towards its CP2030 target.
