The line graph depicts electricity production in terawatt-hours in France from the year 1980 to 2012. Four sources of energy are contributing, with nuclear being the highest overall, while thermal and hydroelectric power have similar generating capacities and lastly, renewable energy seeing a change only after 2000.
In 1980, the thermal source produced around 120 TW-h, gradually decreasing to 50 TW-h in 1985 and continuing generating over and under 50 TW-h units until 2012. Hydroelectric electricity also commenced in 1980, with a capacity of producing approximately 60 to 70 TW-h, fluctuating around the 60 TW-h unit mark until 2012.
While the nuclear source started at just around 50 TW-h units in 1980, there was a dramatic increase in its ability to produce electricity, reaching a peak of approximately 425 TW-h in 2005 and falling to just over 400 TW-h in 2012. Conversely, renewable sources were not incorporated in power generation until the year 2000, gradually growing to approximately 30 to 40 TW-h units until 2012.
In summary, nuclear was the highest power-generating source, with hydroelectric and thermal contributing around the similar range of units, and finally, renewable being the lowest with relatively very little electricity production.
