The given Pie Charts represent level of electricity manufacture by fossil fuels in Australia and France in 1980 and 2000.
Overall, in this 20 years in Australia coal dramatic grew up and natural gas and oil almost appeared. In the same time in French became more popular nuclear power. Natural gas almost appeared as well as in Australia.
Australia had a big changes in fuel sources. For example, in 1980 coal was 50 unit, then in 2000 it is increased and reach 130 unit. While Nuclear power grew up only for 16 unit. As for Natural gas and Hydro power they are suspenseful decreased and reached in 2000 2 units respectively.
As for France, we can see that in 1980 Hydro power, Coal were 20 units. Then in 2000 Coal remained the same, but Natural gas dramatically went down and was 2 unit. However, Oil and Hydro power didn’t show big changes. Nevertheless, Nuclear Power illustrated the biggest changes. In 1980 it took 15 unit, but in 2000 riced up to 126 unit.
In conclusion, in both counties using of electricity power were big changes. As we can see, that capacity of units got bigger. In Austria in 1980 the piechart contained 100 unites, in 2000 it contained 170 units. Moreover, France in 1980 took 90 units, but in 2000 total production became to 180.
