The United Kingdom has made significant strides in wind energy over the past decade, achieving record production levels in 2025. Wind power has become the largest renewable electricity source in the U.K., contributing about 44% of the country’s total electricity generation. This marks a slight decrease from 50.5% in 2024, with fossil fuels, primarily natural gas, accounting for 32.3% of electricity generation.
In 2025, wind energy generated over 85 TWh of power, nearly 30% of the Great Britain electricity supply, with offshore wind contributing a record 17.7%, or 52 TWh. The CEO of RenewableUK, Tara Singh, highlighted the substantial private investments expected in offshore wind projects, noting that onshore wind is now significantly cheaper than new gas plants.
The early months of 2026 saw a 31% increase in power from wind farms compared to the same period in 2025. This boost has helped the U.K. reduce its reliance on fossil fuels and enhance energy security, especially amid global oil and gas shortages exacerbated by geopolitical disruptions.
New onshore wind project applications in England reached a decade-high, with significant growth in the project pipeline since the lifting of the ban on onshore wind in 2024. While Scotland leads the U.K. in onshore wind capacity, plans are underway to create a vast offshore wind network in the North Sea, potentially generating 100 GW of power.
The U.K. Offshore Wind Report indicated a substantial pipeline of 93 GW in fixed and floating offshore wind capacity, potentially increasing employment in the sector significantly by 2030. The recent acceleration in wind energy development is expected to play a crucial role in diversifying the U.K.’s energy mix and enhancing energy security for the future.
