The pie charts depict information about the amount of electricity which was produced by fuel in two nations of Europe between 1980 and 2000.
Overall, it is starkly apparent that production of electricity in Australia mostly relied on coal, and it increased significantly throughout 20 years. In addition, in France it remained constant; electricity production by nuclear power rose sharply. In contrast, use of natural gas and hydro dropped dramatically over the period shown.
In detail, it is evident that the total production of electricity rose significantly in both countries, from 100 units, 90 units, to 170 units and 180 units, respectively. Natural gas and oil declined from 20 units, 10 units, to 2 units in Australia. In contrast, the amount of electricity which was produced by hydropower and coal increased from 20 units, 50 units, to 36 units and 130 units, respectively.
Turning to the remaining pie charts, in France the main source for electricity was nuclear power in 2000, accounting for a significant portion of the total production with 126 units. This number shifted from 25 units in 1980. Additionally, usage of oil for fuel increased gradually from 20 units to 25 units. The least sources for electricity in France were natural gas and hydropower in 2000, at 2 units. However, in 1980 it reposted 25 units for natural gas and 5 units for hydropower.
