The pie charts depict the units of electricity produced by different fuel sources in Australia and France in the years 1980 and 2000.
Overall, both Australia and France witnessed significant changes in the fuel sources used for electricity production from 1980 to 2000, with a shift towards more reliance on coal and nuclear power in both countries.
In Australia, coal was the dominant fuel source for electricity production in both 1980 and 2000, with a substantial increase from 50 units in 1980 to 130 units in 2000. Notably, oil and hydro power saw a decrease in their contributions to electricity production, while natural gas remained relatively stable at 20 units in both years. The overall electricity production in Australia also experienced a notable increase, from 100 units in 1980 to 170 units in 2000.
Contrastingly, in France, nuclear power emerged as the primary fuel source for electricity production in 2000, accounting for a significant portion of the total production with 126 units. This was a marked shift from 1980, where coal had a higher contribution to electricity production with 25 units. Additionally, natural gas saw a notable increase from 5 units in 1980 to 25 units in 2000. On the other hand, the contribution of coal drastically decreased to only 5 units in 2000. The overall electricity production in France doubled from 90 units in 1980 to 180 units in 2000, reflecting a substantial growth in the energy sector.
