New clean power record for GB

Almost three-quarters of the electricity generated in Great Britain in 2024 came from clean power sources, according to new data.

The latest Energy Trends report by the Department for Energy Security and Net Zero found that 73.8% came from renewables and nuclear, up from 68.3% in 2023.

The Government has set a target of reaching 95% clean power by 2030, and this is the first time that official statistics on progress towards that target have been published.

The report also shows that the percentage of electricity generated UK-wide by renewables in April to June (Q2) this year hit a new quarterly record of 54.5%, up from 51.7% in Q2 2024.

On Saturday when Storm Amy was battering the country, wind produced 69.6% of GB electricity according to the system operator.

Meanwhile, analysis by Carbon Brief found electricity demand on the island of Great Britain has been fully covered by the output of clean-energy sources for a record 87 hours in 2025 to date, up from just 2.5 hours in 2021 and 64.5 hours in all of 2024. The data doesn’t include Northern Ireland which is part of the separate all-Ireland grid
