The provided chart illustrates the variations in energy production across five distinct sources in France over a ten-year period.
Overall, energy generated from gas, coal, and alternative sources experienced upward trends, while petrol and nuclear energy saw a decline in their relative shares. Additionally, gas and coal emerged as the primary sources of energy production by the end of the period.
In 1995, gas was the leading source of energy production, accounting for approximately 29% of the total output. Coal production was a close second, matching this figure at nearly 29%. In contrast, petrol usage saw a significant decline over the decade, losing its dominant position as alternative energy sectors began to show relative growth.
Regarding the remaining energy sectors, nuclear power accounted for 6.40% of the overall national production. Meanwhile, other natural and renewable energy sources made up the smallest share, contributing just 4.90% to the total energy mix.
