France has the greatest share of nuclear power in total electricity generation worldwide. In 2024, nuclear energy accounted for over 67 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 January 2025, the monthly nuclear power production in the country reached 38.6 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 2025. France came in second with over 63 gigawatts electric. 61 nuclear reactors are under construction worldwide, with China leading with 28 units and India following with six. Additionally, the global nuclear landscape saw the permanent shutdown of four reactors in 2024, highlighting ongoing shifts in energy production and policy.
