The charts display units of electricity generation by different fuel resources such as:coal, oil, natural gas, hydro power and nuclear power in Australia and France between 1980 and 2000
Overall, the vast majority of proportion in Australia was occupied by coal, whereas for France, it was the nuclear power. Moreover, the contribution of natural gas experienced a tremendous decline in both type of countries. Notably, the units vary in each pie chart: 100-170 and 90-180.
On the one hand, coal accounted for 50% of electricity production in Australia in 1980, and this figure doubled in 2000. Furthermore, despite the initial contribution of natural gas and hydro power at identical 20, natural gas dropped tenfold to 2, whereas hydro power increased exponentially, rising to 36, in 2000. Additionally, oil production dipped from 10 to 2, from 1980 to 2000.
On the other hand, in France the generation of hydro power, coal and oil were also at similar numbers (20-25), but their shares changed at different rates over time. In comparison, the percentage of natural gas production saw a considerable plunge, estimating at 2, when the oil and coal productions stood at equal numbers (25) . Ultimately, a significant trend can be observed at nuclear power, where it surged remarkably from 15 to 126, between 1980 and 2000.
