According to official figures, renewable sources supplied 50.4 % of the United Kingdom’s electricity in 2024—up from 46.4 % in 2023. Total renewable generation reached a record 143.7 TWh, overtaking fossil fuels in annual output. Wind power emerged as the dominant clean energy source.

For the first time ever, renewables delivered more than half of the UK's electricity, marking a significant milestone. 

Renewables accounted for 50.4 % of total electricity generation, compared with 31.8 % for fossil fuels—primarily gas (down from 36.7 % in 2023). This continued decline in fossil fuel reliance underscores a shift in the energy mix.

Clean electricity (including renewables and nuclear) reached a record 64.7 % of the total in 2024 (184.3 TWh), up from 60.3 % in 2023. New figures from the Department for Energy Security and Net Zero’s Digest of UK Energy Statistics (DUKES) attribute this rise to expanded offshore wind and solar capacity.

Wind power alone hit a new benchmark, generating 29.5 % of UK electricity (84.1 TWh)—exceeding the previous record of 28.1% (82.3 TWh). It contributed 58% of all renewable electricity, with offshore wind at 17.2% (48.9 TWh) and onshore wind at 12.3 % (35.1 TWh).

Solar power provided 5.2 % (14.8 TWh), while nuclear contributed 14.25 % (40.6 TWh) in 2024. Meanwhile, fossil fuel generation dropped to 31.5 % (89.7 TWh), a level not seen since the 1950s.

Jane Cooper, Deputy CEO of RenewableUK, commented that “these landmark figures show that renewables now form the backbone of the UK’s electricity system. Clean power is stabilising prices and offering benefits to consumers. But to fully capitalise on this momentum, we must reform the electricity markets and grid infrastructure so households and businesses reap the maximum benefit from clean energy growth.”

She added that the upcoming clean energy auction could attract up to £53 billion in new private investment, particularly in offshore wind projects.
