U.K. solar generation hits record 15 GW as gas falls to historic low
Britain’s electricity grid hit 98.8% zero-carbon power for a half-hour stretch on April 22, 2025, with gas squeezed down to just 1.2% of the mix. A day later, solar set its own new peak at 15.4 gigawatts, and wind had broken records just weeks before. The shift is striking when you zoom out: renewables made up 3% of Britain’s electricity in 2000, and 44% by 2025. As one of the world’s largest economies shows that running a national grid on almost entirely clean power is genuinely workable, it offers a glimpse of what energy security and climate progress can look like together — and a roadmap others can follow.
