Countries with high dependence on nuclear energy

According to Britannica, one method of releasing nuclear energy is by controlled nuclear fission in devices called reactors, which now operate in many parts of the world for electricity.

As of May 2024, the World Nuclear Association reported that Nuclear power supplies roughly 10% of global electricity via approximately 440 operational power reactors. It also contributes to nearly a quarter of the world's electricity with low carbon emissions.

However, there are several countries where nuclear energy is not just a part of the energy mix but a dominant force. Here is a list of countries based on data provided by Ember and Energy Institute:

France

France has the highest dependence on nuclear energy, with 65% of its electricity coming from nuclear power plants. It has a large nuclear power programme and is home to some of the oldest and most prominent nuclear power plants worldwide.

Slovakia

Slovakia relies heavily on nuclear energy, with 62% of its electricity generated from nuclear power plants. The country has four operational nuclear reactors, with two more under construction.

Ukraine

Ukraine relies heavily on nuclear energy, with 55% of its electricity generated from nuclear power plants. The country has 15 operational nuclear reactors, with more under construction.

Hungary

Hungary's dependence on nuclear energy stands at 44%. The Paks Nuclear Power Plant is the country's only nuclear power plant but is being expanded to increase its capacity.

Finland

Finland's dependence on nuclear energy stands at 42%. The country has four operational nuclear reactors, with a fifth under construction.

Belgium

Belgium's dependence on nuclear energy stands at 41%. The country has three operational nuclear power plants, which are scheduled to be shut down by 2025 to diminish dependency levels.

Czech Republic

The Czech Republic's dependence on nuclear energy stands at 40%. The country has six operational nuclear reactors, with two more under construction.
