The given graphs provide information about the proportion of electricity production by fuel force in two countries in 1980 and 2000.
Looking from an overall perspective, it is readily apparent that Australia started utilizing coal as an electricity source more frequently than it was before. Although, the preference for nuclear power grew in France.
As we can see, Australia initially produced totally 100 units, where the first quarter of a pie chart is attributed to coal, which took a half of 100, following with hydro power and natural gas which were similar in number, and oil as the least utilized source. Meanwhile, in 2010, the popularity of coal significantly increased up to 130. Also grew the preference for hydro power from 20 to 36 units, which was the second largest percentage, producing 170 units in total.
In France, in 1980, the leading position can be attributed to both coal and natural gas, having 25 units. However, in 2000 the majority of electricity was produced by nuclear power, from total 180 units making 126. The coal stayed constant, however others, decreased dramaticallly, except oil which was oppositely increased from 20 to 25.
