The pie charts presented delineate the distributions in electricity manufacure across Australia and France in 1980 and 2000.
Overall, it is evident that the total production of both countries increased over the period. Furthermore, coal and nuclear power predominated over Australia and France respectively.
In the realm of Australia, coal is recorded as the most produced with 50 units in 1980, and 130 units in 2000, which held the largest portions. Hydro power exhibited with a relatively modest figure at 20 units, then gradually increased before ultimately culminated at 36 units. Natural gas followed a similar trajectory as hydro but it appeared with a more significant plummet – from 20 to 2 units, which shared the same ending figure with oil. Additionally, the growth by 70 units along with the concentration on coal-related production underscores essential role and the development of Australia.
Turning to France, the charts illustrate several differences from Australia. In 1980, the distribution between sources was quite equivalent when coal and natural gas both occupied 25 units, closely followed by oil with 20 units, nuclear and hydro at 15 and 5 units respectively. Surprisingly, nuclear power emerged as the standout source, witnessing a remarkable increase of roughly 100 units. Natural gas and hydro experienced a drop down to 2 units, while the proportions of coal and oil remained nearly unchange. However, it is notable that the overall units of electricity production in France doubled, reflecting a substantial growth in this country.
