The given pie chart illustrated the units of electricity production by fuel source in Australia and France in 1980 and 2000.
As can be seen from the chart, the total production in Australia had a considerable increase of almost trouble to reach 170 units in 2000. Compared four kind of fuel sources in both two years, coal and hydro power were the most important energy with 70 and 166 units out of total each year. Moreover, there was a dramatically increase in both coal (50 to 130 units) and hydro power (20 to 36 units) from 1980 to 2000. Conversely, two other fuel sources are decline dramatically from 20 and 10 to 2 units in both natural gas and oil.
Regarding France, in 1980, three fuel source were produced relatively are coal, oil and natural gas from 20 to 25 units. However, hydro power and nuclear power were less produced the three other fuel sources with 15 units of nuclear power and 5 units of hydro power. Remarkably, there was a wild growth in the units of electricity production by nuclear power with 126 units.
