Sample Question 1 Cam 7, Test 4
Thepie charts below show units of electricity production by fuel source in Australiaand France in 1980 and 2000.
Discovering Trend 1
•In Australia, the consumption of electricity rose from 100 to 170units in total production in the period of 20 years.
•Coal remained as the primary source and account for 130 units outof 170 units in 2000, 80 units higher than that of 1980.
Basic Fact 1
•There are five different sources of electricity, namely coal,oil, natural gas, hydro power and nuclear power.
Discovering Trend 2
•The nuclear power emerged as the dominant source of electricity.
•The consumption of natural gas slided down significantly duringthis 20 years.
Basic Fact 2
•The pie compares the conditions in Australia and France.
•The figures are in units of total production.
Pie – Sample
The charts compare the sources ofelectricity in Australia and France in the years 1980 and 2000. Betweenthese years electricity production almost doubled, rising from 100 units to 170in Australia, and from 90 to 180 units in France.
Main Body 1
In 1980, Australia used coal as the mainelectricity source (50 units) and the remainder was produced from natural gas,hydro power (each producing 20 units) and oil (which produced only 10 units). By 2000, coal had become the fuel for more than 75% of electricityproduced and only hydro continued to be another significant source supplyingapproximately 20%.
Main Body 2
In contrast, France used coal as a sourcefor only 25 units of electricity in 1980, which was matched by natural gas. Theremaining 40 units were produced largely from oil and nuclear power, with hydrocontributing only 5 units. But by 2000 nuclear power, which was not used atall in Australia, had developed into the main source, producing almost 75% ofelectricity, at 126 units, while coal and oil together produced only 50 units.Other sources were no longer significant.
Overall, it is clear that by 2000, thesetwo countries relied on different principal fuel sources: Australia relied oncoal and France on nuclear power.
