The pie charts provide information about the amount of electricity produced by five types of fuel in Australia and France during two last decades of the XXth century. Overall, there was a clear predominance of coal in Australian industry, whereas almost all sources of energy were evident in equal measure in France in 1980 with nuclear power being over other fuel options in 2000.
A closer examination of the data reveals that half of the whole electricity (50 units to be precise) had been made with the use of coal in Australia by 1980. Likewise, this energy source made up the biggest part of the proportion (130 units) in 2000. At the same time, other fuel varieties accounted for just 20 units (Natural Gas and Water power respectively) and 10 (Oil) in 1980 which is several times less than the coal share. In terms of 2000, there other fuel types were similarly hardly represented, since just 36 units of hydro power were registered and 2 of oil and gas correspondingly.
Looking at the French graphs, there was quite a different situation. Thus, in 1980 all kinds of energy sources apart from water accounted for 15-25 units and none of them reported a noticeable prevalence. Nevertheless, in 2000 such predominance occurred, since nuclear power invaded 126 units, while coal and oil made up 25% both and gas with water 2% respectively.
