Britain has achieved a new milestone in renewable energy, generating enough electricity from wind to supply more than 23 million homes, the National Energy System Operator (NESO) announced Monday.

On December 5 at 5:30 p.m. GMT, wind turbines across the country produced 23,825 megawatts (MW), surpassing the previous record of 22,711 MW set in November. At the peak, wind energy accounted for nearly half (47.4%) of the nation’s electricity demand.

NESO highlighted that Britain now hosts five of the world’s largest offshore wind farms, with a total of 47 operational offshore sites contributing around 17% of the country’s electricity output. The country also set a solar generation record earlier this year, producing 14 gigawatts (GW) in July, which at the time supplied almost 40% of the nation’s power.
