Cambridge IELTS 9 Model Answer (Test 4, Task 1)

Test 4 Task 1

The line graph outlines energy consumption in the USA from 1980 to the present day, with further projections up until 2030. Use is recorded in quadrillion units and is divided in to six categories, almost all of which display a general increase over time.

For the entirety of the period covered, petrol and oil usage is the highest. In 1980, 35 quadrillion units were used, and this dipped a little initially before rising steadily to a projected peak of 50 quadrillion units by 2030. This rate of increase is matched by that of coal, whose usage climbs from around 16 quadrillion units to just over 30 quadrillion units over the same period of time. This means that, by 2030, it is expected to be the second-most used fuel, whereas in 1980 natural gas usage was higher, at 20 quadrillion units. However, usage of this fuel is expected to remain at 25 quadrillion units from 2015 until 2030.

At the other end of the spectrum, nuclear fuel and solar / wind fuel usage is not predicted to change drastically, with increases from 3 to 8 and 3 to 6 quadrillion units respectively. In slight contrast, usage of hydropower, which was also 3 quadrillion units in 1980, dropped very slightly to approximately 2.5 quadrillion units in 2011, and it is not expected that this level of usage will change in the future.

A few points.

  1. In the introduction, explain what the X and Y axes display – time and quadrillion units.
  2. If there are any trends that are the same, make reference to that – coal / petrol and oil increase at a very similar rate.
  3. Similarly, highlight contrasts. Coal and Natural Gas change places between 1980 and 2030.
  4. Decide how to group your information. Here, I’ve decided to group three high and three low together in paragraphs.
