The pie charts illustrate the proportion of energy output of France in 1995 and 2005. Overall, while the share of coal, gas, nuclear power, and other energy sources increased to varying degrees, that of petrol exhibited the reverse. Additionally, coal retained its leading position throughout the period.
Focusing first on the energy production in 1995, coal represented the most significant figure, reaching at a chart high of 29.80%. Following instantly behind were gas and petrol, whose respective shares stood at 29.63% and 29.27%. Finally, while nuclear sources of energy accounted for 6.40%, unspecified supplies comprised a mere 4.90% in the generation of energy across France.
Turning to the shifts in the mix by 2005, coal remained the primary source of energy for France, slightly rising to 30.93%. Whereas the proportion of gas also saw a negligible growth (30.31%), the figure for petrol plummeted to 19.55%, still ranking third in energy production. The shares of nuclear and unknown energy sources climbed markedly, reaching 10.10 and 9.10%, respectively.
