The table illustrates the proportion of five distinct fuel types used to generate electricity in four European nations in 2015.
Overall, nuclear power was by far the largest source in France, whereas Germany, Italy, and Sweden showed a more varied energy mix. Fossil fuels (coal and natural gas) constituted a significant portion of electricity generation in Germany and Italy, while hydro and renewables were notable in Sweden.
In Germany, coal was the primary source, accounting for 40%, followed by natural gas at 25%. Nuclear power contributed 15%, with hydro and renewables each at 10%. In contrast, France relied heavily on nuclear energy, which supplied 70% of its electricity. Coal and renewables were minimal contributors, both at 5%.
Italy's electricity generation was dominated by natural gas at 45% and coal at 15%. Hydroelectric power played a substantial role there at 20%, with nuclear and renewables each making up 10%. Sweden had the most diverse mix, with nuclear power at 40%, hydro at 27%, and renewables at 25%. Coal and natural gas had very small shares, at 3% and 5% respectively.
