Nuclear Data Hub
The Data Hub is a collection of data and charts about nuclear energy. Arranged by topic, the Hub helps users to understand nuclear energy.
Rank of countries by nuclear electricity generation
Nuclear generation by country, 2024
Nuclear electricity production versus share of electricity from nuclear by country
Fourteen countries produce more than a quarter of their electricity from nuclear; just 3 countries account for nearly 60% of all nuclear electricity generation
