UK Power Turned Dirtier in 2025, Risking 2030 Green Grid Target

Britain increased the share of electricity generated from fossil fuels last year for the first time in four years, a reversal that highlights the challenges facing the government’s plan to run a clean power system by 2030.

Greater reliance on gas-fired power to offset a decline in nuclear output pushed up emissions, even as renewable generation hit a record. Data compiled by Bloomberg using National Energy System Operator figures show that expanding wind and solar alone will not be enough to meet the target, leaving the UK grappling with how to curb reliance on gas-fired power by the end of the decade.
