The 4 pie charts illustrate units of electricity production by fuel source between 2 countries: Australia and France, compared with 1980 and 2000 your.
Overall, the total Production of units of electricity by fuel source both in Australia and France had increased significantly from 1980 to 2000.
The electricity production which has produced in Australia in 1980, mostly came from Coal by 50 units, follow by Natural Gas, Hydro Power and oil which are about 20 units, 20 units and to units respectively. Converserly, in 2000, the total production increased almost double to 170 units. Coal, still, significantly rose to 180 units and Hydro Power slightly went up to 86 units while the rest of fuel sources dropped into 2 units.
France started the total production about 90 units in 1998. Divided into 5 fuel sources and most of production are using Coal and Natural Gas which are about 25 units. Follow by oil, Nuclear Power and Hydro Parer which are 20 units, 15 units and 5 units respectively. However, in 2000, the amount of production jumped to 180 units in France. There were dramatically increased of Nuclear power to 126 units and slightly rose to 25 units of oil. But, Coal remained the same and other sources went down to 2 units which has been clear.
