The pie charts illustrate the type of sources used in the production of electricity in France in the years 1990 and 2010.
Overall, there was a significant shift to a nuclear power in the electricity production in France by the end of the period.
The fossil fuels were the most common types of fuels to generate electricity in 1990. Natural gas, oil, and coal accounted for around a quarter of the electricity production each. However, this type got out of France favor, as the halving was observed in the coal and oil utilizing. Natural gas application saw a substantional decrease to 4% by the year 2010.
As for the renewable sources of energy, hydro and nuclear powers were used less than fossil fuels in 1990, at around 6% and 17% respectively. However, these numbers witnessed a change, albeit to a different degree. The hydro power usage decreased slightly by 4%. The nuclear power,on the other hand, became dominant in the electricity production, as it contributed for a staggering 67% of electricity produced by 2010.
