The given pie charts demonstrate units of electricity generated by fuel source in two different countries: Australia and France in 1980 and 2000.
Overall, coal is the main source for electricity in Australia in both years, while nuclear power in France became the major source in 2000. Furthermore, the total production units in both countries inclined over the period.
Regarding the units of electricity production in Australia, in 1980, coal contributed 50 units to it, whereas hydro power and natural gas produced the same unit, 20 units. The lowest unit, which was 10 units, came from oil. In 2000, coal became the main source with 130 units, and it was followed by hydro power at 36 units. Ultimately, the units of electricity produced from natural gas and oil were exactly the same at 2 units each.
Regarding the units of electricity production in France, in 1980, coal and natural gas produced the same amount at 25 units; then, the figure for oil was higher than that for nuclear power, with 20 units compared to 15 units. Subsequently, hydro power generated the lowest at 5 units. In 2000, nuclear power is the main source with 126 units; meanwhile, the figure for coal was still constant that was the same unit with that for oil. Both natural gas and hydro power generated 2 units each.
