The pie charts compare the units of electricity production by different fuel sources in Australia and France in the years 1980 and 2000.
In Australia, electricity production increased from 100 units in 1980 to 170 units in 2000. Coal was the dominant fuel source, contributing 50 units in 1980 and significantly rising to 130 units in 2000. Oil and natural gas usage remained relatively stable, with minor increases from 10 and 20 units in 1980 to 2 and 36 units, respectively, in 2000. Hydro power remained unchanged at 20 units, while nuclear power was introduced in 2000 with a small contribution of 2 units.
In contrast, France’s electricity production got doubled from 90 units in 1980 to 180 units in 2000. The most striking change was the dramatic increase in nuclear power usage, from 15 units in 1980 to 126 units in 2000, making it the dominant source. Coal and oil maintained the same contribution of 25 units each, while natural gas decreased slightly from 25 to 2 units. Hydro power remained unchanged at 5 units.
Overall, Australia relied primarily on coal for electricity production, whereas France shifted significantly towards nuclear power over the two decades.
