The pie graphs illustrate how many units of electricity were produced in two different countries in 1980 and 2000.
Looking from an overall perspective, it is readily apparent that coal represented a gradual rise in Australia while this figure remained stable in France.
Looking at the details, in Australia, coal, which accounted for half of the total units in 1980 and made up 130 units in 2000, is by far the largest category. With an increase of 16 units, hydro power ranked second. Additionlly, in 2000, natural gas and oil both of them comprised same units.
Looking at the other country, nuclear power represented 126 units in 2000. Natural gas and hydro power made up 2 units in 2000 while both of them showed more units in 1980. With 25 units, coal illustrated constantly in both years.
