The pie charts compare the proportion of 5 different fuel sources in France’s electricity production. Overall, the percentage of nuclear power in generating electricity improved substantially but the reverse is true for the remaining sources (coal, oil, natural gas, hydropower)
In 1990, the electricity generation was somewhat equally distributed among 4 sources, with hydropower contributing the least. Coal and natural gas were the main sources of electricity, each representing 28%. This was distantly followed by oil with 22% and then nuclear power with 17%. Lastly, only 6% of electricity came from hydropower.
However, by 2010, the proportions in the mix had changed considerably. Nuclear power became the major electricity generation source, the proportion of which rose to a staggering 67%. By contrast, the percentage of coal and oil dropped noticeably to the same 13% while that of nuclear gas witnessed the biggest fall, declining to just 4%. Finally, the contribution of hydropower became even smaller, constituting 2%.
