Britain's Electricity Generation in January 2026: Wind Leads at 37% Share
In January 2026, wind energy supplied 37% of Britain's electricity generation, the highest for January in five years. Gas contributed 31%, down from 38% in January 2025. Electricity imports accounted for 11%, while nuclear power fell to 10%. Biomass generation increased to 7%, and zero-carbon sources provided 61% of total generation. Carbon intensity decreased to 144 gCO₂/kWh, reflecting stronger contributions from renewables. The transition to cleaner energy continues, with challenges in sustaining high renewable output and reducing reliance on gas.

In January 2026, wind energy dominated Britain's electricity generation at 37%, up from 27% in January 2025. Gas generated 31%, a decrease from 38% last year, while electricity imports contributed 11%.
Nuclear power dropped to 10%, and biomass generation rose to 7%. Zero-carbon sources accounted for 61% of total generation, significantly improving from 43% in January 2025. Carbon intensity fell to 144 gCO₂/kWh, down 14% year-on-year. This month marked a strong start for the year, with wind reclaiming its position as the leading source, although gas remained crucial for winter demand and nuclear output declined.
