Which country relies more on nuclear power?

• A. Spain
• B. France
• C. Romania
• D. United Kingdom

Answer: (B)

Nuclear power’s share in a country’s electricity mix explains why one country relies on it more than others. France has put heavy emphasis on nuclear energy for decades, building a large fleet of reactors to provide most of its electricity. This results in a much higher portion of French power coming from nuclear plants compared with the other countries listed, which rely more on renewables, natural gas, or coal. Spain, for example, uses a sizable amount of renewable energy and imports, with nuclear playing a smaller role. The United Kingdom uses a diverse mix that includes some nuclear, but not at the same high share as France. Romania has limited nuclear capacity, so its electricity comes from other sources as well. Because of this contrast, France stands out as the country that relies most on nuclear power among the options.
