China is set to become the world’s dominant nuclear power producer.
Based on existing and planned projects, its total capacity could reach nearly 186 gigawatts, far surpassing the U.S., which currently leads globally. This shift reflects a broader push to secure reliable, low-carbon energy as electricity demand rises.
This chart,via Visual Capitalist's Tasmin Lockwood,ranks countries by current and prospective nuclear capacity, using data fromGlobal Energy Monitor.
The U.S. currently leads nuclear energy production with a capacity of 102,475 megawatts, exceeding France by more than 35,000 MW.
China ranks third today at 60,898 MW, but that is set to change as new plants come online.
Dive into the data, which includes sites of any capacity as of September 2025, below:
This shift has major geopolitical implications. Countries that expand nuclear capacity can reduce reliance on imported fossil fuels while strengthening energy security and grid stability.
If all planned projects are completed, China will lead with 185,812 MW, followed by the U.S. at 117,910 MW and France at 75,590 MW.
France remains a historic leader in nuclear energy, with around 69% of its electricity generated from the technology.
The UK was home to the world’s first commercial nuclear power plant, which came online in 1956, but later scaled back its use of nuclear. The government is now aiming for a “golden age of nuclear,” though current commitments totaling 15,394 MW would rank the country just 12th globally.
