The pie charts below show units of electricity production by fuel source in Australia and France in 1980 and 2000

The pie chart illustrates units of electricity production by fuel of two different countries in year 1980 and 2000

As can be clearly observed,in year 1980,units of electricity by coal was half production in Australia. After two year,coal production was increased by 80 units.In contract,the units of electricity by oil was 10 units in year 1980.where as in year 2000,it was drastically decreased of 8 units. However the production of the natural gas was 20 units in 1980. After two year,production was down 18 units in 2000. The hydro power was 20 units production and it was rosed 16 units in 2000. The total production was 100 units in year 1980 and after 2 year, it was surged 70 units from Australia

Further analysis of the chart,From France,units of electricity production by coal was 25 units in year 1980 and 2000. Meanwhile, the oil production was increased 5 units. Additionally , the nuclear power production was 15 units in 1980. After that it was drastically elevated and picked 126 units in 2000. In contrast, the natural gas and hydro power production was 25 and 5 units respectively decreased to the production of 2 units in year 2000.

Overall, The highest production of coal in 2000 from Australia. Where as, In France , the highest units of electricity production of nuclear power in year 2000.
