Analysis on 25th anniversary of commissioning of UK’s first offshore wind farm finds the technology is now main source of electricity from North Sea, overtaking gas and generating around 10 per cent more power.

Offshore wind has reduced the UK’s spending on imported fuels by at least £30bn (in 2024 real prices) to-date, finds new analysis by the Energy and Climate Intelligence Unit (ECIU).
The UK’s first offshore wind farm was at Blyth Harbour in Northumberland, and since late 2000, the cumulative generation from offshore wind totalled over 400TWh as of mid-2025, which otherwise would likely have been provided by a mixture of gas and coal.

25 years into their deployment, UK offshore wind farms currently produce almost 50TWh of electricity per year (17 per cent of UK total generation).
