The pie charts given illustrate levels of electricity production the amount of electrictiy produced/ generated by using five different sources of fuel fuel source in Australian and France in 1980 and 2000. Overall, the both units (như vậy là có 2 units thôi sao) of electricity of two countries experienced significant changes in their source structures (viết thế này không thể hiện được vấn đề gì cả) (1, số lượng unit tăng) (2, 2 nước này có xu hướng sử dụng sources of fuel khác nhau).
The amount of electricity production by coal The amount of Coal used to... in for Australia increased by 80 units, from... to.../ increasing to... while the figure for France still remained the stable amount at 25 units after 20 years. There was a decrease in electricity production from using oil of in Australia (nên viết Australia saw a decreas in...), from 10 units to only 2 units, on the other hand, that of France rose by 5 units, going up to 25 in 2000.
As can be seen, the number (không đếm được) of electricity production made (chỉ dùng used by/ using) from natural gas for both Australia and France both dropped by 18 units and 23 units respectively. In addition, the number of that produced from (diễn đạt thoáng đi) hydro power became more significant in Australia, making up for over a third of the country's electricity grew by 16 units, while France witnessed a small decrease by 3 units (chuyển về % vì bên trên đã khá nhiều units rồi). Moreover, the charts expressed that Last but not least, it is clear that only France produced electricity by using nuclear power and the figure for that showed a huge increase from only 15 units in 1980 to 126 units in 2000 (đoạn này nên nhận xét, thay vì nêu số liệu: this became the most considerable source for the nation).
