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. Here’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, it’s important to remember that there are some smaller countries not featured above where nuclear is still an important part of the electricity mix.

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

RankCountryNuclear Share of Electricity Mix
#1France 🇫🇷70.6%
#2Slovakia 🇸🇰53.1%
#3Ukraine 🇺🇦51.2%
#4Hungary 🇭🇺48.0%
#5Bulgaria 🇧🇬40.8%
#6Belgium 🇧🇪39.1%
#7Slovenia 🇸🇮37.8%
#8Czechia 🇨🇿37.3%
#9Armenia 🇦🇲34.5%
#10Finland 🇫🇮33.9%
#11Switzerland 🇨🇭32.9%
#12Sweden 🇸🇪29.8%
#13South Korea 🇰🇷29.6%
#14Spain 🇪🇸22.2%
#15Russia 🇷🇺20.6%
#16Romania 🇷🇴19.9%
#17United States 🇺🇸19.7%
#18Canada 🇨🇦14.6%
#19United Kingdom 🇬🇧14.5%
#20Germany 🇩🇪11.3%

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.

It’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 mix—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.

Visualizing Global Energy Production in 2023

Fossil fuels accounted for 81% of the energy mix.

Global primary energy consumption reached a new record of 620 exajoules (EJ) for the second consecutive year in 2023, up from 607 exajoules in 2022.

This graphic shows the sources of energy used globally in 2023, measured in exajoules. Data is from the 2024 Statistical Review of World Energy by the Energy Institute, released in June 2024.

Fossil Fuels Accounted for 81% of the Energy Mix

Despite efforts to decarbonize the economy, fossil fuels still accounted for over 80% of the global energy mix in 2023.

Oil was responsible for 32% of the energy consumed around the world, followed by coal (26%) and then natural gas (23%).

Energy SourceConsumption in exajoulePercentage (%)Fossil Fuel
Natural Gas14423%Yes
Nuclear Energy254%No
Other Renewables518%No

The Asia-Pacific region was responsible for nearly 80% of global coal output, with significant contributions from Australia, China, India, and Indonesia.

Global coal consumption also continued to rise, exceeding 164 EJ for the first time ever.

China remains the largest consumer of coal, accounting for 56% of the world’s total consumption. However, in 2023, India’s coal consumption exceeded the combined total of Europe and North America for the first time.

Oil consumption, in particular, rebounded strongly last year compared to 2022, largely due to China relaxing its zero-COVID lockdown policies.

Renewables’ share of total primary energy consumption reached 14.6%, an increase of 0.4% over the previous year. Together with nuclear, they represented roughly 19% of total primary energy consumption.

Renewables like solar and wind accounted for 8% of the energy generated in 2023, followed by hydroelectric (6%) and nuclear (4%).

Visualized: The Growth of Clean Energy Stocks

Visual Capitalist partnered with EnergyX to analyze five major clean energy stocks and explore the factors driving this growth.



This line chart shows the growth of clean energy stocks and hints at their cumulative five-year returns.

The Growth of Clean Energy Stocks

Over the last few years, energy investment trends have shifted from fossil fuels to renewable and sustainable energy sources. Long-term energy investors now see significant returns from clean energy stocks, especially compared to those invested in fossil fuels alone.

For this graphic, Visual Capitalist has collaborated with EnergyX to examine the rise of clean energy stocks and gain a deeper understanding of the factors driving this growth.

Sustainable Energy Stock Performance

In 2023, the IEA reported that 62% of all energy investment went toward sustainable sources. As the world embraces sustainable energy and technologies like EVs, it’s no surprise that clean energy companies provide solid returns for their investors over long periods.

Taking the top-five clean energy stocks by market cap (as of April 2024) and charting their five-year cumulative returns, it is clear that investments in clean energy are growing:

CompanyPrice: 01/04/2019Price: 12/29/20245-Year-Return %
First Solar, Inc.$46.32$172.28272%
Enphase Energy, Inc.$5.08$132.142,501%
Consolidated Edison, Inc.$76.55$90.9719%
NextEra Energy, Inc.$43.13$60.7441%
Brookfield Renewable Partners$14.78$26.2878%

But how does this compare to the performance of fossil fuel stocks?

When comparing the performance of the S&P Global Oil Index and the S&P Clean Energy Index between 2019 and 2023, we see that the former returned 15%, whereas the latter returned an impressive 41%. This trend demonstrates the potential for clean energy stocks to yield significant returns on an industry level, sparking optimism and excitement for potential investors.

A Shift In Returns

With global investment trends moving away from traditional, non-sustainable sources, the companies that could shape the energy transition provide investors with alternative opportunities and avenues for growth.

One such company is EnergyX. The lithium technology company has patented a groundbreaking technology that can improve lithium extraction rates by an incredible 300%, and its stock price has grown tenfold since its first offering in 2021.
