Renewable energy sources now account for a sizable portion of the electricity mix. And the United Kingdom is well on its way to developing an entirely renewable and carbon-free electricity system.
2020 was the first year in UK history that electricity was primarily generated by renewable energy, with 43 percent of power coming from a combination of wind, solar, bioenergy, and hydroelectric sources.
Wind, solar, hydroelectric, and bioenergy are the four main renewable energy sources used to power the UK today. They generate electricity by harnessing the natural power of the sun, weather, waterways and tides, and organic materials.
