Countries by Nuclear Power Share of Electricity 2024

About This Dataset

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.

✨ AI Insight

France's dominance in nuclear energy is evident, with a substantial 70.6% of its electricity derived from nuclear power, a strategy rooted in the oil crisis of the 1970s. Slovakia and Ukraine follow, but with notable gaps, generating 58.0% and 55.0% of their electricity from nuclear sources, respectively. The data highlights a stark contrast with the United States, where only 18.6% of electricity is nuclear-generated, suggesting a more diversified energy portfolio. Countries like Hungary and Belgium, at 49.0% and 46.0%, respectively, also show significant reliance on nuclear power, yet still fall short of the leaders. This trend indicates a complex interplay of energy policy, public acceptance, and alternative energy sources that shape national energy landscapes.
