Units of electricity by fuel source in Australia
Units of electricity by fuel source in France
The pie charts display electricity generation from different fuel sources in Australia and France in 1980 and 2000. The measurements are in units.
Overall, total production in both countries increased significantly, from 100 to 170 units in Australia and 90 to 180 units in France. In Australia, most electricity was produced using coal in both years, whereas in France nuclear power overtook coal, natural gas, and oil as the main source of electricity supply in 2000.
Australia relied on coal for the majority of its electricity generation in both years; 50 units of electricity were generated from coal in 1980 and this amount went up dramatically to 130 units in 2000. Production from hydropower also showed a climb, to 36 units, while that from natural gas and from oil declined, to 2 units each.
In comparison, most of France’s electricity came from coal, natural gas, and oil, at 25, 25 and 20 units respectively. The other 20 units were generated from nuclear power and hydropower. However, with a dramatic increase to 126 units, nuclear power, which was never used in Australia, became the predominant source of electricity generation in 2000. Burning coal and oil each produced 25 units in 2000, while production from natural gas and from hydropower dropped to only 2 units each.
How to Vary Your Language
You can omit “electricity” and just say “production”. You have already established the context in your introduction paragraph, so when you say ‘production from coal’, readers know you are referring to ‘electricity production from coal’.
You can also use these terms:
the amount of electricity generated
the quantity of electricity produced
Correct: production from coal
production by coal
How to Group Data
In terms of France’s figures in 1980, ‘25’, ‘25’ and ‘20’ are big ones, so I grouped them together. ‘15’ and ‘5’ are smaller ones, so they are grouped together.
Moving on to 2000, “126” is a very significant figure, so I singled it out. For the rest of the figures, I grouped the two “25” together, and the two “2” together.
