Like most countries, the United Kingdom is making swift moves to try to reduce carbon emissions and increase energy security through wind, solar, and other renewables. And as in many other countries, nuclear energy is set to play a large role. The nation already gets about 15% of its electricity from nuclear, and aims to triple its capacity to 24 gigawatts (GW) by 2050, which would cover some 25% of its future electricity needs, all while retiring older gas-cooled nuclear plants.
