The pie charts illustrate the amount of electricity unites produced by 5 various sources: coal, natural gas, nuclear power, oil and hydro power in Australia and France in 1980 and 2000 years.
Overall, it is notable that proportion of a coal usage in Australia, where nuclear power was not used, and nuclear power percent in France increased over two decades.
In Australia, 70 units were added to an overall production, which resulted in a number of 170. The widest section coal went up from 50 in 1980 to 130 in 2000. Hydro power had a modest rise of 16 units, and the biggest decrease accounts to the usage of natural and oil gas, that declined from 20 and 10 in 1980 to 2 each in 2000.
France had a relatively equal proportion of four sources in 1980: coal 25, natural gas 25! oil 20, and nuclear power 15. In 2000, nuclear power had a sharp increase in 111, and became a major source of energy. Coal didn’t have any changes, while oil’s use increased to 25 units and natural gas was almost not used.
