Électricité de France (EDF), the main electricity generation and distribution company in France, is also one of the world's largest producers of electricity. In 2018, it produced around 20% of the European Union's electricity, primarily from nuclear power. France is the smallest emitter of carbon dioxide among the G7, due to its heavy investment in nuclear power. , 72% of the country's electricity is generated by 58 nuclear power plants, the highest proportion in the world. In this context, renewable energies are having difficulty taking off. France also uses hydroelectric dams to produce electricity, such as the Eguzon dam, Étang de Soulcem and Lac de Vouglans.
