The pie charts illustrate the amount of electricity produced from five different fuel sources in Australia and France in 1980 and 2000.
Overall, Australia relied heavily on coal in both years, while France showed a significant shift towards nuclear power by 2000.
In Australia, coal was the dominant source of electricity in 1980, accounting for 50 units out of a total of 100. Natural gas and hydro power each contributed 20 units, while oil made up 10 units and nuclear power was not used. By 2000, total production had risen to 170 units, with coal becoming even more dominant at 130 units. Hydro power also increased to 36 units. In contrast, natural gas and oil dropped sharply to just 2 units each, and nuclear power remained negligible.
In France, the energy mix was more balanced in 1980. Coal and natural gas each generated 25 units, while oil contributed 20 units. Nuclear power produced 15 units and hydro power accounted for only 5 units, out of a total of 90. However, by 2000, total output had doubled to 180 units, and nuclear power became the main source at 126 units. Coal and oil each produced 25 units, whereas natural gas and hydro power declined significantly to just 2 units each.
