About This Dataset

Countries by Nuclear Power Share of Electricity 2024

Countries ranked by the percentage of their national electricity generation provided by nuclear power plants in 2024 according to the International Atomic Energy Agency and IEA data. France generates approximately 70% of its electricity from nuclear power — the highest proportion of any large economy in the world — a legacy of a strategic decision made in the 1970s following the oil crisis that transformed France into the world's most nuclear-dependent major economy and a net electricity exporter.

Analysis

The top three in Nuclear Share of Electricity (%) in 2024 are France (70.6), Slovakia (58) and Ukraine (55). The 8 entries cover a range of 52.0, from 70.6 down to 18.6. First and second are separated by 12.6, so the leader sits inside the field rather than apart from it. The field is close behind: 6 of the 8 sit at half the leader's figure or above (35.3+).
