The line graph compares the amount of electricity produced by four different power stations in France, over a period of 30 years.
It is clear that nuclear power stations were by far the highest in terms of electricity generation while renewables was the least produced during the same period.
In 1980, thermal was the largest means of energy source, generating around 120 tw/h of electricity. The figures for nuclear and hydroelectric energy were relatively the same, recording roughly 75 tw/h. At the same time, the production of renewable energy made up only a negligible amount. After a year, in 1981, nuclear power production overtook the thermal, becoming the biggest source of energy for the rest of the timeline.
Between 1980 and 1987, there was a significant fall in the amount of thermal energy, to about 45, which was nearly three times as low as the initial level. By 2012, the this amount had reached just under 50 tw/h following some fluctuations. By contrast, the line for nuclear power stations saw a dramatic increase, reaching over 400 tw/h in 2012. As for hydroelectric power source, there were a lot of fluctuations during from the beginning to the end, accounting for almost the same amount as in 1980, approximately 53 tw/h. Renewables followed a different pattern as opposed to other means of electricity. During the whole period, there was a steady rise in the amount of renewable energy, eventually making up roughly 20 tw/h.
