The pie charts compare various sources of energy production in France, namely coal, gas, petroleum, nuclear, and others, over a period of ten years (1995 and 2005).
Overall, coal and gas have been the primary sources of energy production during this period, maintaining a consistent level of contribution. In contrast, petroleum usage for energy production has declined, while the usage of nuclear and other sources has increased by 2005.
To begin with, coal contributed 29.80%, which is the highest proportion among the different sources in 1995, and maintained a steady contribution of 30.93% in 2005, remaining the highest value among all sources. Gas also served as a major energy source, contributing steadily at 29.63% in 1995 and experiencing a slight increase to 30.21% in 2005.
Nuclear and other sources saw significant increases in their contributions by 2005. In 1995, nuclear energy accounted for 6.40%, rising to 10.10% in 2005. Furthermore, the contribution from other sources also increased sharply, going from 4.90% in 1995 to 9.10% by 2005.T
