The given pie chart illustrates the fuel sources of electricity in two different countries between 1980 and 2000. Overall, Australia used coal to produce electricity the most while natural gas became the largest source of power in France at the end of the period.
In Australia, the usage of coal was the largest at 50 units in 1980, before increasing to 130 units two decades later. Similarly, hydro power rose from 20 to 36 units during the same period. In contrast, Australia’s reliance on natural gas and oil declined from 20 and 10 units to 2 units which were the smallest sources at the end of the period. In total, electricity production in this nation went up from 100 to 170 units within 20 years.
Finally, the total production of electricity in France was 90 units in 1980, which doubled in 20 years. In 1980 coal and natural gas at 25 units, then natural gas dramatically decreased to 2 units, while coal remained the same in 2000. Otherwise, nuclear power became the major source of electricity from 1980 at 15 units significantly increased to 126 units in 2000. Next, oil rose only 5 units from 1980 to 2000, while the smallest source is hydropower dropping from 5 to 2 units at the same period of time.
