Nuclear Power Production by Country

Nearly 450 reactors around the world supply various nations with nuclear power, combining for about 10% of the world’s electricity, or about 4% of the global energy mix.

But while some countries are turning to nuclear as a clean energy source, nuclear energy generation overall has seen a slowdown since its peak in the 1990s.

The above infographic breaks down nuclear electricity generation by country in 2020 using data from the Power Reactor Information System (PRIS).

Ranked: The Top 15 Countries for Nuclear Power

Just 15 countries account for more than 91% of global nuclear power production. Hereโ€™s how much energy these countries produced in 2020:

In the U.S., nuclear power produces over 50% of the country’s clean electricity. Additionally, 88 of the country’s 96 operating reactors in 2020 received approvals for a 20-year life extension.

China, the world’s second-largest nuclear power producer, is investing further in nuclear energy in a bid to achieve its climate goals. The plan, which includes building 150 new reactors by 2035, could cost as much as $440 billion.

On the other hand, European opinions on nuclear energy are mixed. Germany is the eighth-largest on the list but plans to shutter its last operating reactor in 2022 as part of its nuclear phase-out. France, meanwhile, plans to expand its nuclear capacity.

Which Countries Rely Most on Nuclear Energy?

Although total electricity generation is useful for a high-level global comparison, itโ€™s important to remember that there are some smaller countries not featured above where nuclear is still an important part of the electricity mix.

Hereโ€™s a breakdown based on the share of nuclear energy in a country’s electricity mix:

RankCountryNuclear Share of Electricity Mix
#1France ๐Ÿ‡ซ๐Ÿ‡ท70.6%
#2Slovakia ๐Ÿ‡ธ๐Ÿ‡ฐ53.1%

#18Canada ๐Ÿ‡จ๐Ÿ‡ฆ14.6%
#19United Kingdom ๐Ÿ‡ฌ๐Ÿ‡ง14.5%
#20Germany ๐Ÿ‡ฉ๐Ÿ‡ช11.3%

European countries dominate the leaderboard with 14 of the top 15 spots, including France, where nuclear power is the country’s largest source of electricity.

Itโ€™s interesting to note that only a few of these countries are top producers of nuclear in absolute terms. For example, in Slovakia, nuclear makes up 53.6% of the electricity mixโ€”however, the country’s four reactors make up less than 1% of total global operating capacity.

On the flipside, the U.S. ranks 17th by share of nuclear power in its mix, despite producing 31% of global nuclear electricity in 2020. This discrepancy is largely due to size and population. European countries are much smaller and produce less electricity overall than larger countries like the U.S. and China.

The Future of Nuclear Power

The nuclear power landscape is constantly changing.

There were over 50 additional nuclear reactors under construction in 2020, and hundreds more are planned primarily in Asia.

As countries turn away from fossil fuels and embrace carbon-free energy sources, nuclear energy might see a resurgence in the global energy mix despite the phase-outs planned in several countries around he globe.

The World’s Biggest Oil Producers in 2023

Just three countries accounted for 40% of global oil production last year.

The World’s Biggest Oil Producers in 2023

Despite efforts to decarbonize the global economy, oil still remains one of the world’s most important resources. It’s also produced by a fairly limited group of countries, which can be a source of economic and political leverage.

This graphic illustrates global crude oil production in 2023, measured in million barrels per day, sourced from the U.S. Energy Information Administration (EIA).

Three Countries Account for 40% of Global Oil Production

In 2023, the United States, Russia, and Saudi Arabia collectively contributed 32.7 million barrels per day to global oil production.

Oil Production 2023Million barrels per day
๐Ÿ‡บ๐Ÿ‡ธ U.S.12.9
๐Ÿ‡ท๐Ÿ‡บ Russia10.1
๐Ÿ‡ธ๐Ÿ‡ฆ Saudi Arabia9.7

๐Ÿ‡ง๐Ÿ‡ท Brazil3.4
๐Ÿ‡ฆ๐Ÿ‡ช UAE3.4
๐Ÿ‡ฐ๐Ÿ‡ผ Kuwait2.7
๐ŸŒ Other22.8

These three nations have consistently dominated oil production since 1971. The leading position, however, has alternated among them over the past five decades.

In contrast, the combined production of the next three largest producersโ€”Canada, Iraq, and Chinaโ€”reached 13.1 million barrels per day in 2023, just surpassing the production of the United States alone.

In the near term, no country is likely to surpass the record production achieved by the U.S. in 2023, as no other producer has ever reached a daily capacity of 13.0 million barrels. Recently, Saudi Arabiaโ€™s state-owned Saudi Aramco scrapped plans to increase production capacity to 13.0 million barrels per day by 2027.

In 2024, analysts forecast that the U.S. will maintain its position as the top oil producer. In fact, according to Macquarie Group, U.S. oil production is expected to achieve a record pace of about 14 million barrels per day by the end of the year.

How Much Does the U.S. Depend on Russian Uranium?

Despite a new uranium ban being discussed in Congress, the U.S. is still heavily dependent on Russian uranium.

How Much Does the U.S. Depend on Russian Uranium?

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

The U.S. House of Representatives recently passed a ban on imports of Russian uranium. The bill must pass the Senate before becoming law.

In this graphic, we visualize how much the U.S. relies on Russian uranium, based on data from the United States Energy Information Administration (EIA).

U.S. Suppliers of Enriched Uranium

After Russia invaded Ukraine, the U.S. imposed sanctions on Russian-produced oil and gasโ€”yet Russian-enriched uranium is still being imported.

Currently, Russia is the largest foreign supplier of nuclear power fuel to the United States. In 2022, Russia supplied almost a quarter of the enriched uranium used to fuel Americaโ€™s fleet of more than 90 commercial reactors.

Most of the remaining uranium is imported from European countries, while another portion is produced by a British-Dutch-German consortium operating in the United States called Urenco.

Similarly, nearly a dozen countries around the world depend on Russia for more than half of their enriched uraniumโ€”and many of them are NATO-allied members and allies of Ukraine.

In 2023 alone, the U.S. nuclear industry paid over $800 million to Russiaโ€™s state-owned nuclear energy corporation, Rosatom, and its fuel subsidiaries.

It is important to note that 19% of electricity in the U.S. is powered by nuclear plants.

The dependency on Russian fuels dates back to the 1990s when the United States turned away from its own enrichment capabilities in favor of using down-blended stocks of Soviet-era weapons-grade uranium.

As part of the new uranium-ban bill, the Biden administration plans to allocate $2.2 billion for the expansion of uranium enrichment facilities in the United States.
