Britain's shift towards renewable energy has reached an impressive milestone, with wind power setting new records and dominating the country's electricity mix.
On Sunday evening (December 15), UK wind turbines generated a record-breaking 22,243 megawatts (MW) of electricity, providing 54% of the nation's power supply, according to data from the National Energy System Operator (NESO). This surpassed the previous record of 21,998 MW set on January 10, 2023.
The momentum continued into early Monday morning when wind accounted for 70% of the electricity mix, reaching 21,123 MW at 4:30 AM. The achievement was largely driven by stronger-than-average winds, particularly in Scotland, where many turbines are located.
Progress toward a clean energy future
Wind power, a renewable and environmentally friendly energy source, contrasts sharply with fossil fuels like coal and gas, which emit significant amounts of carbon dioxide. Harnessing wind energy involves turbines, both offshore and on land, where the wind spins rotor blades to generate electricity.
The record aligns with the UK government's commitment to decarbonize the electricity grid by 2030, marking significant progress toward a clean and sustainable energy system. Barnaby Wharton, Director of Future Electricity Systems at RenewableUK, celebrated the milestone: "It’s fantastic to see wind energy breaking records again, keeping Britain powered through the coldest, darkest months while enhancing our energy security."
UK energy mix: a shift underway
The UK's energy mix constantly fluctuates based on demand and supply from various sources, including wind, gas, solar, biomass, and nuclear. On Tuesday morning, wind contributed 29.8% of the mix, while gas, a dominant fossil fuel, made up 37%. Other sources included nuclear (11.8%), imported electricity (8.6%), biomass (6%), and hydro (2%).
Despite gas remaining a major energy source, experts predict wind power will overtake it in the near future. Dr. Simon Evans, Senior Policy Editor at Carbon Brief, forecasts wind dominance by 2030: "The UK already gets nearly as much electricity from wind as from gas. By the end of the decade, wind will dominate our power supply, while gas use will plummet."
Moving away from fossil fuels
The UK has already made strides in reducing its reliance on fossil fuels. In September, the country shut down its last operational coal-fired power station at Ratcliffe-on-Soar, marking the end of nearly 150 years of coal-powered electricity.
To further expand clean energy, major projects like the Eastern Green Link are in development. These energy 'superhighways' will transport wind-generated electricity from Scotland to England, bolstering supply and grid resilience.
Future of wind power
Currently, there are an estimated 11,000 wind turbines across the UK, with plans for thousands more to be built. As Britain advances toward its clean energy goals, wind power is set to play a leading role in reducing carbon emissions, enhancing energy security, and combating the climate crisis.
