The graph below shows electricity production (in terawatt hours) in France between 1980 and 2012

This

graph depicts 4 resources of energy production in France over 30

years

.

Overall

,

while

hydroelectric, renewables, and thermal experienced a negligible change, the most dramatic increase was seen in nuclear. Standing at 50

terawatt

hours

, electricity produced by nuclear power was 50 times higher than renewable sources, the lowest.

After

this

number rocketed and hit the highest point at 451

terawatt

hours

in 2005, it decreased slightly to 440

terawatt

hours

at the end

of the observed period.

By contrast

, before renewables sources witnessed a moderate growth of 25

terawatt

hours

in 2010,

this

figure remained unchanged over 15

years

.

On the other hand

, the number of electricity produced by thermal, which stood at 125

terawatt

horse, was the highest resource in 1980 declined by 75 units over 5

years

then

remained unchanged from 1985 to 2010, at 50

terawatt

.

Although

after fluctuating around 75

terawatt

over 25

years

, hydroelectric remained stable at 50

terawatt

hours

for the rest of the observed period
