The given pie charts provide information about units of electricity productions by various fuel sources in Australia and France in the years 1980 and 2000. It is readily apparent that both countries produced almost two-fold more electricity in 2000 than in 1980.
In 1980, the main fuel source in Australia was coal, accounting for 50% of all sources. Ranked second were hydro power and natural gas, at 20% and Australia used oil the least, with 10%. In 2000, the number of coal used rose for around 75% as well as that of hydro power increasing to 36%. Meanwhile, Australia used less natural gas and oil with 2%. It is interesting to note that Australia never used nuclear power to produce electricity.
In marked contrast, in 1980,coal and natural gas were clearly shown as the most common sources producing electricity in France, at 25%. The remainder was produced from oil (20%) and nuclear power (5%). However, by 2000, nuclear power had become the primary source, producing almost 75% of electricity, at 126 units, while coal and oil had made up just 50 units out of 180 units. Other sources were no longer popular.
From an overall observation, the most common source producing electricity in both countries was different: Australia relied on coal, whereas France depended on nuclear power.
