The four pie charts illustrate how many units that the electricity had produced by fuel source, as such coal, oil, natural gas, hydro power, and nuclear power in two different nations, namely, Australia and France between 1980 and 2000.
Overall, it is clear that the coal was the main fuel source using to produce the electricity power in Australia, while oil was the least popular for 20 years. In contrast, at the beginning of the year, coal was also predominant fuel source to produce the electricity in France but after 20 years, nuclear power was taken over. Furthermore, natural gas was the least popular using to produce electricity over the period.
As can be seen, in Australia, the total of the electricity production was 100 units in 1980. The coal used to produce electricity was 50 units in Australia, whereas hydro power and natural gas were only 20 units. Then, only 10 units of oil was used. However, in 2000, the total of product was 170 units. The unit of coal and hydro power increased to 130 units, and 36 units, respectively. Meanwhile, natural gas and oil dropped to only 2 units.
On the other hand, in France, the total production was 90 units in 1980. Only 25 units of coal and natural gas were used, and 20 units of oil. Moreover, they used only 15 units of nuclear power and 5 units of hydro power. By contrast, in the following 20 years, there was a dramatic increase in the total production to 180 units. The substantial amount of the electricity production was from nuclear power which was 126 units, and 25 units from coal and oil. Then, natural gas and hydro power were only 2 units.
