Nuclear Electricity Generation by Country

Nuclear electricity generation by country measures the amount of electricity generated from nuclear power plants in each country, measured in quadrillion British thermal units (quad Btu) per year. The statistics are based on the U.S. Energy Information Administration's (EIA) International Energy Statistics. The table covers 33 countries with a reported 2024 generation value, from 2019 to 2024. The World total stood at 14.83 quad Btu in 2024, up from 14.5 in 2023.

Nuclear electricity generation measures the electricity produced by nuclear reactors, as reported in the EIA dataset.

The United States alone accounted for about 55 percent of the World total in 2024, and the United States and China together for about 65 percent; the top three countries accounted for about 74 percent, the top five for about 83 percent, and the top ten for about 90 percent. The United States' generation was about 5.3 times that of China, the second-largest generator.

Nuclear Electricity Generation Around the World

In Asia, China (1.54) leads, ahead of South Korea (0.64) and Japan (0.28); India (0.19) and Pakistan generate smaller volumes. In Europe, France (1.23) is the largest generator, ahead of Russia (0.74), Spain (0.18), Ukraine (0.18) and Sweden.

In North America, the United States (8.17) dominates, followed by Canada (0.28) and Mexico. In South America, Brazil and Argentina generate small volumes. In the Middle East, the United Arab Emirates generates the largest volume. In Africa, only South Africa reports nuclear generation.

Comparison of Nuclear Electricity Generation and Total Generation

From the same EIA dataset, nuclear electricity generation is reported separately from other electricity generation indicators. The comparison is limited to the indicators taken directly from the same EIA tables.

Global Structure in This Dataset

Nuclear generation figures are highly concentrated: the top five generators account for about 83 percent of World generation in 2024, while the top ten account for about 90 percent. The United States remained the largest generator in every year shown. France ranked second in 2019, while China moved into second place in 2020 and remained there through 2024.

Largest Changes in Nuclear Electricity Generation, 2023-2024

France recorded the largest increase among the listed countries, rising from 1.09 quad Btu in 2023 to 1.23 in 2024 (up 0.14, about 12.8 percent). United States rose by 0.07, and China by 0.06.

Germany recorded the largest decline, falling from 0.02 to 0 quad Btu (down 0.02, about 100.0 percent). Taiwan fell from 0.06 to 0.04 (down 0.02), while Canada declined by 0.01. The World total rose from 14.5 to 14.83 quad Btu (up 0.33, about 2.3 percent).

France's nuclear generation increased from 0.95 quad Btu in 2022 to 1.09 in 2023 and 1.23 in 2024, continuing its recovery after the 2022 decline. Germany's nuclear generation declined from 0.24 quad Btu in 2019 to 0 in 2024, with the final shutdown in 2023.

Total and Ratio Analysis for 2019-2024

The World total for nuclear generation moved between 14.26 and 14.83 quad Btu in this period. It was 14.83 in 2019, 14.4 in 2020, 14.67 in 2021, 14.26 in 2022, 14.5 in 2023, and then 14.83 in 2024. The United States accounted for the largest absolute generation throughout the period.

Methodology

The statistics are based on the U.S. Energy Information Administration's (EIA) International Energy Statistics. Values refer to nuclear electricity generation, in quadrillion British thermal units (quad Btu) per year as in the source, and 2024 figures are from the INTL.27-12 series where listed. Where no value is available, the cell is left empty. A value of 0 indicates that the source reports zero generation. The sum of the 33 individually listed countries is 14.8296 quad Btu, which rounds to the reported World total of 14.83 quad Btu. This page covers nuclear generation only and does not include other generation sources, consumption, capacity or reserves, which are reported separately in the source.
