These graphs illustrate the amount of electricity produced by fuel sources in Australia and France in 1980 and 2000.
According to these pie charts, the total amount of electricity production by fuel source in Australia and France both increased during the period, which increased 70 units and 90 units respectively.
However, the amount of electricity produced by different sources changes irregularly in 20 years. In Australia, coals are still the main producer of electricity, but they accounted for over 75% of fuel source in electricity production in 2000, which surged 25% compared to 1980. As the technology developed, nuclear power produced more electricity, occupied 20% of electricity production in 2000. In contrast, other materials like oil, natural gas and hydro power, experienced a dramatic decline to only 2 units in 2000. The situation in France seems similar to Australia, though the main contributor of electricity was nuclear power, making up 70 % in total. The electricity produced by hydro power and natural gas still decreased to 2 units as same as Australia.
