The given pie chart illustrates the units of electricity production by fuel source in Australia and France for the years 1980 and 2000.
As shown in the chart, Australia’s total electricity production saw a significant increase, reaching nearly 170 units in 2000. When comparing the four types of fuel sources over the two years, coal and hydropower were the primary sources of energy, contributing 70 and 166 units, respectively, each year. Additionally, there was a dramatic increase in both coal (from 50 to 130 units) and hydropower (from 20 to 36 units) from 1980 to 2000. In contrast, the other two fuel sources—natural gas and oil—experienced a steep decline, dropping from 20 and 10 units to just 2 units each.
In France in 1980, coal, oil, and natural gas produced a relatively similar output, ranging from 20 to 25 units. However, hydropower and nuclear power produced less than the other three fuel sources, generating 15 units for nuclear power and 5 units for hydropower. Notably, there was substantial growth in electricity production from nuclear power, which skyrocketed to 126 units.
