What percentage of France's electricity production came from nuclear power in 2016?

• A. 60%
• B. 50%
• C. 40%
• D. 72.3%

Answer: (D)

France’s electricity mix in 2016 was dominated by nuclear power, reflecting its policy of using a large fleet of reactors to produce low-carbon electricity. About 72.3% of the electricity generated domestically came from nuclear plants, meaning nuclear was the primary source of power from the grid that year. The other options would indicate a much smaller role for nuclear than it actually had in 2016, when renewables and fossil fuels contributed far less to the total than nuclear did. This illustrates how France relied on nuclear energy to meet most of its electricity demand.
