Nuclear share of domestic electricity generation worldwide 2023, by country
France has the greatest share of nuclear power in total electricity generation worldwide. In 2023, nuclear energy accounted for almost 65 percent of the European country's total electricity production. By comparison, the share of nuclear electricity generation in the United States stood at less than 20 percent.
Nuclear power production in France
Nuclear power is essential to France’s energy plan, as it meets a significant amount of the country’s electrical needs. In 2024, the monthly nuclear power production in the country varied from 27 to 36 terawatt-hours. France has a sizable fleet of reactors, which helps to maintain a steady supply of electricity while reducing its carbon footprint.
Global nuclear landscape
The United States holds the highest nuclear power capacity globally, with approximately 97 gigawatts electric across its 94 reactors as of August 2024. France came in second with over 61 gigawatts electric. Worldwide, 59 nuclear reactors are under construction, with China leading with 25 units and India following with seven. Additionally, the global nuclear landscape saw the permanent shutdown of five reactors in the previous year, highlighting ongoing shifts in energy production and policy.
