The U.K. was the birthplace of commercial nuclear energy, but now generates just a fraction of its power from it — big investments are underway to change that.
The country once had more nuclear power stations than the U.S., USSR and France — combined. It was a global producer until 1970 but hasn’t completed a new reactor since Sizewell B in 1995.
Today, the country takes the crown not for being a leader in atomic energy, but for being the most expensive place in the world to build nuclear projects.
Nuclear energy accounted for just 14% of the U.K.’s power supply in 2023, according to the most recent data from the International Energy Agency, trailing its European peers and well behind frontrunner France at 65%.
There is ambition to change that and have a quarter of the U.K.’s power come from nuclear by 2050. Nuclear is considered an attractive bet gas it’s a low-carbon, constant energy source that can act as a baseload to complement intermittent sources like renewables.
