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

The four circle charts provide data about

units

of electricity manufacturing by fuel source in different countries

such

as Australia and France from 1980 to 2000.

Overall

, the usage of coal was prevalent among Australian people,

while

nuclear power became the main source of electricity in France throughout the given time.

According to

the first two charts which describe

units

of energy by various fuel in Australia, in 1980 the production of natural gas and hydropower (20

units

) were equal 1980.

However

, after 20 years, producing coal was placed as a source of energy: oil and natural gas. It is interesting to note that the total production of hydropower increased from 20 to 36

units

. Referring to the remaining pie charts which illustrate the amount of France's energy sources, about 15

units

of nuclear power were produced in 1980, but after two decades

this

sort of power replaced other sources of fuel

such

as natural gas and hydropower.

Nevertheless

, the

units

of coal remained in the same quantity in 2000.
