The pie charts illustrate the proportion of energy sources which were used to generate electricity in France in 1990 and 2010.
Overall, each fuel type accounted for about one-fifth of the percentage used to produce electricity in 1990 (excluding hydro power). However, by 2010, these figures have changed noticeably. Nuclear power had risen to become the most used source for energy, while the others’ percentage fell substantially.
In the year 1990, three fuel sources that were mostly transformed into energy were natural gas (28%), coal(28%), and oil (22%). On the other hand, nuclear, and hydro power took up the least proportion at just 17%, and 6%, respectively.
There were massive changes to the proportion just two decades after. Nuclear power, which used to be amongst the least popular, increased dramatically to over two-thirds of the total (67%). In contrast, the rest of the fuel source decreased in their percentage—coal and oil had dropped to just 13%, while natural gases and hydro power fell to 4% and 2%, respectively.
