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

The charts compare the proportions of electricity units manufactured by 5 diffirent fuel catogories in Australia and France in 1980 and 2000.
It is noticeable that the units of electricity dramatically increased over the period shown in both Australia and France, from 100 units to 170 units and 90 units to 180 units, respectively.
In Australia, the majority of electricity was manufactured by coal, in which a half electricity units in 1980 rose to 130 units over the time period. It saw a similar proportion of production by hydro power and natural gas, with 20 units while only 10 units produced by oil in 1980. After 2 decades, hydro power was the second popular energy to manufacture electricity, with 36 units.
In terms of France, natural gas, coal and oil contributed the similar proportion in electricity production with 25, 25 and 20 units, respectively. Over 20-year period, nuclear was responsible for nearly three quarters of production while oil and coal together produced 50 units.
