The pie charts below show units of electricity production by fuel source in Australia and France in 1980 and 2000.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Given are the pie charts which illustrate how much various fuels had roles in generating electricity in different years and countries. Overall, as time went by, the generated units of electricity increased considerably.

To begin with, in Australia, in 1980, coal was the chief source by which 50 units of electricity were produced, and at the time, hydro power and natural gas ranked second (each 20 units). They were followed by oil with 10 units. As indicated, by 2000 not only did coal maintain its position but also it had raised its role in the production (130 units). Following that, 36 units belonged to hydro power, and each of natural gas and oil generated 2 units. On the whole, during 20 years in Australia, electricity generation grew from 100 units to 170 units.

By contrast, in France, in 1980, in terms of electricity production, coal, oil, and natural gas were almost at the top of the list with respectively, 25 units, 20 units, and 25 units. Moreover, the remainder was supplied by taking advantage of nuclear power (15%) and hydro power (5%). Interestingly, in 2000, nuclear power predominated other fuels, constituting 126 units of the production, and each of coil and oil comprised 25 units. Also, the rest was provided by natural gas (2%) and hydro power (2%). Generally, in France, within 20 years electricity production doubled from 90 units to 180 units.

To sum up, in both nations electricity generation rose over time by using various sorts of fuel.
