The following line graph depicts the amount of electricity produced by four sources in France over a period of 32 years.
Overall, it is inffered that the Nuclear source was by far the most usable mean among these 4 sources, while Renewables had the lowest contributions.
In 1980, although Thermal and Nuclear power sources had more or less of 75 terawatt hours, Hydroelectric power played as a main source of energy producer. Interestingly, from one year later, Nuclear started to surpass them in generating power which became the most significant power provider in the entire period shown.
It is noticable that not only Renewables mean had the lowest level of electricity generation among them, it but also reamined steady by 2005. Since 2005, it went up gradually to about 25 terawatt hours. It is important to note that both Hydroelectric and Thermal provider witnessed a fluctuational patterns within these years and became roughly stable.
