The pie chart illustrates how many percentages of electricity production by 5 types of fuel source such as: coal, oil, natural gas, hydro power and nuclear power there are in France throughout 20 years from 1990 to 2010.
Overall, the nuclear power contribution experienced an increase, whereas the other four categories showed a dip over the whole period. As can be seen, the highest percentage of electricity production changed from coal to nuclear power by 2010, while the lowest one which was hydro power remained unchanged.
Nuclear power stood at 17% in 1990, while this figure regained up to 67% in the following 20 years. Compare with nuclear power with the high contribution, hydro power witnessed a fall from 6% to 2% and stayed the lowest percentage.
Conversely, coal and oil accounted for 28% and 22%, respectively. Both of them fell a drop into the same amount of 13% in 2010. On the other hand, natural gas saw a different trend and plunged from 28% to 4%.
