The pie charts below show units of electricity production by fuel source in Australia and France in 1980 and 2000.

Question

 

The pie charts illustrate the amount of electricity generated by different types of fossil fuel sources between 1980 and 2000

Overall,  total electric production in both countries experienced an upward trend. Additionally, while coal is the main source of production in Australia, the amount of electricity was mainly produced by nuclear power. 

In Australia, in 1980, 50% of the total production was produced by coal, at 50 of the total 100 units. Meanwhile, the units of electricity produced by natural gas and hydropower were the same, doubling oil with 10 units. In 2000, the total production increased steadily to 170 units. There was an increase of 80 units in the figure for coal, in contrast, that for natural gas and oil decreased to 2 units. 

In France,  the total production was 10 units lower than those in Australia at the beginning of the surveyed period. Both natural gas and coal were used to generate 25 units in comparison with 15 units by nuclear power and 20 units by oil. In the two-decade later, the total production was doubled and nuclear was the vital source of the production of electricity at 126 units whereas coal and oil remained the contribution of 50 units in total.
