Line Graph – Sample
Sample Question 1 Cam 9, Test 4
Thegraph gives information from a 2008 report about consumption of energy in theUSA since 1980 with projections until 2030.
Discovering Trend 1
•The consumption of the first three energy sources is much largerthan that of the other three.
•Their consumption was generallyontherise.
Basic Fact 1
•There are six different energy sources, namely petrol andoil, coal, natural gas, nuclear, solar/wind, and hydropower.
Discovering Trend 2
•The consumption of nuclear energy, solar/wind energy, and hydropower showslittlevariation throughout the entire period.
Basic Fact 2
•The time (horizontal axis) is from 1980 to 2030.
•While the period 1980-2010 is in the past, the period2015-2030 is in the future.
•The present year is 2012.
•The figures (vertical axis) are in quadrillion units.
Line Graph – Sample
The graph shows energy consumption in theUS from 1980 to 2012, and projected consumption to 2030.
Main Body 1
Petrol and oil are the dominant fuelsources throughout this period, with 35 quadrillion (35q) units used in 1980,rising to 42q in 2012. Despite some initial fluctuation, from 1995 there wasa steady increase. This is expected to continue, reaching 47q in 2030.
Main Body 2
Consumption of energy derived fromnatural gas and oil is similar over the period.From 20q and 15q respectively in 1980, gas showed an initial fall and coal agradual increase, with the two fuels equal between 1985 and 1990. Consumptionhas fluctuated since 1990 but both now provide 24q. Coal is predicted toincrease steadily to 31q in 2030, whereas after 2014, gas will remain stable at25q.
Main Body 3
In 1980, energy from nuclear, hydro andsolar/wind power was equal at only 4q. Nuclear hasrisen by 3q, and solar/wind by 2. After slight increases, hydropower hasfallen back to the 1980 figure. It is expected to maintain this level until2030, while the others should rise slightly after 2025.
Overall, the US will continue to rely onfossil fuels, with sustainable and nuclear energy sources remaining relativelyinsignificant.
