he given pie charts depict information about the units of different sources used for electricity in Australia and France in the timeline between 1980 and 2000.
Over the period, the total production of electricity by 5 types of resources increased, however, natural gas became least consumed source for electricity.Moreover,in Australia dominant source is coal and nuclear power in French.
To begin, in Australia ,the index of coal and nuclear power stood at 50 and 20 units ,respectively, further, the former gone through significant growth accounting 130 units in a year 2000,whereas nuclear power increased by 16 units comprising 36 units.Meanwhile, oil and natural gas,after 20 years,became the least relevant source for electricity manufacturization. Oil decreased by 90 percent and natural gas experienced 5 time reduction in use ,therefore both sources stood at 2 units in 2000.
Turning to the France, nuclear power became primary source after a dramatic increase from 15 units to 126 units in 20 years ,while second major resources for electricity are oil and coal forming 25 units each in 2000.Coal usage remained stable ,but oil underwent a sligth increase in 5 units between 1980 and 2000,likewise, the lowest allocated sources toward electricity were natural gas and hydro power after a fall .Worth to mention ,hydro power decreased by two fifth, while natural gas witnessed a drop in 23 units.
