The chart illustrates how many electricity produced by four sources in France during the period from 1980 to 2002.
As can be seen from the graph, while there were upwards trends in the amount of electricity generated by nuclear and renewables, the opposite was true for thermal and hydroelectric. In addition, the figure for nuclear energy increased the most.
In 1980, nuclear power provided about 70 TW-h, in comparison with the negligible amount of renewables. For the next 32 years, the amount of electricity generated by nuclear grew significantly to reach a peak at 450 TW-h in 2005, before falling slightly to above 400 TW-h in 2012. At the same time, after remaining stable until 1995, the figure for renewables experienced a gradual climb to 25 TW-h in 2012.
By contrast, thermal energy generated the most electricity with around 120 TW-h in 1980, whereas the figure for hydroelectricity at 70 TW-h. The amount of electricity provided by thermal dropped substantially by 70 TW-h in 1985, which was followed by a fluctuation around 50 TW-h until 2012. Similarly, the figure for hydroelectric fluctuated between 170 and 180 from 1980 to 2012.
