Global nuclear power production 1985-2023

Global nuclear power generation reached 2,552 terawatt-hours in 2023, a year-over-year increase of nearly three percent. Figures have seen a mostly increasing trend since 2012 but decreased in 2020 and 2022. The global nuclear landscapeFollowing 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 at 2.66 petawatt-hours. 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 389.5 in 2021 to 372 in 2023. Largest consumers of nuclear energyConsumption of nuclear power varies widely across the world, with the United States, China, and France making up more than 58 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 are at least 30 years old in 2023. Meanwhile, in France, nuclear power is the leading source of electricity, accounting for a 65 percent share of electricity production.

全球核能发电量于2023年达到2,552太瓦时，较上年同期增长近三成。自2012年以来，数据呈现总体上升趋势，但2020年和2022年有所下降。日本福岛核灾难于2011年3月发生之后，部分国家如德国承诺逐步淘汰或限制核能用于能源生产。然而，自2013年起，核能发电量持续增长，并于2019年超过福岛事故前的水平，达到2.66拍瓦时。尽管如此，一些国家依然坚决反对建设核能设施。总体来看，近年来核能反应堆的关闭数量有所增加，全球核能容量从2021年的389.5万下降至2023年的372万。核能消耗量最大的国家，美国、中国和法国占全球核能消耗量超过58%。美国许多反应堆的建设始于1974年，但在2010年代之前变化不大，当时批准了新的反应堆建设。相应地，截至2023年，美国大多数核能反应堆至少已有30年历史。与此同时，在法国，核能是主要的电力来源，占电力生产的65%。
