Renewables
Wind, solar, and other renewable electricity generation from NESO data.
Renewable electricity comes from sources that naturally replenish: wind (onshore and offshore), solar PV, hydroelectric, wave, tidal, and biomass. Nuclear is low-carbon but not classified as renewable.
Renewables have grown rapidly in the UK, from around 7% of generation in 2010 to over 40% by 2023. Offshore wind has been the largest contributor to this growth.
Generation by Source
Wind Generation
Daily electricity from grid-connected wind farms. Includes onshore and offshore wind.
Solar Generation
Daily electricity from solar PV. Shows clear seasonal variation.
Source: National Energy System Operator (NESO) Historic Generation Mix dataset.
Update frequency: Daily aggregates from half-hourly grid data.
Note: Renewables share is a daily average of half-hourly percentages. Generation values are in GWh per day.
