The line graph compares the amount of electricity produced in France using four different sources of power over a period of 32 years.
- Overview - 2 sentences, 2 main points
It is clear the nuclear power was by far the most important means of electricity generation over the period shown. Renewables provided the lowest amount of electricity in each year.
- Details - 2 paragraphs, compare the lines
In 1980, thermal power stations were the main source of electricity in France, generating around 120 terawatt hours of power. Nuclear and hydroelectric power stations produced just under 75 terawatt hours of electricity each, and renewables provided a negligible amount. Just one year later, nuclear power overtook thermal power as the primary source of electricity.
- Details
Between 1980 and 2005, electricity production from nuclear power rose dramatically to a peak of 430 terawatt hours. By contrast, the figure for thermal power fell to only 50 terawatt hours in 1985, and remained at this level for the rest of the period. Hydroelectric power generation remained relatively stable, at between 50 and 80 terawatt hours, for the whole 32-year period, but renewable electricity production saw only a small rise to approximately 25 terawatt hours by 2012.
