Global nuclear power generation reached terawatt-hours in 2024, a year-over-year increase of nearly percent. Figures have seen a mostly increasing trend since 2012 but decreased in 2020 and 2022.Â
The global nuclear landscape
Following the Fukushima nuclear disaster in Japan in March 2011, some countries, such as Germany, vowed to phase out or limit nuclear power for energy production. Nevertheless, nuclear power generation has been steadily increasing since 2013, surpassing pre-Fukushima levels in 2019. Still, some countries remain staunchly opposed to building nuclear power facilities. Overall, more nuclear power reactors have shut down in recent years, and the global nuclear capacity dropped from in 2021 to *** in 2024.Â
Largest consumers of nuclear energy
Consumption of nuclear power varies widely across the world, with the United States, China, and France making up almost ** percent of the world’s global consumption. Many reactors in the United States began construction by 1974, but little changed until the 2010s when new reactors were approved for construction. In turn, the vast majority of nuclear power reactors in the United States were at least ** years old in 2023. Meanwhile, in France, nuclear power is the leading source of electricity, accounting for ** percent of electricity production.
