Task 1 (Line Graph) – Consumption of energy in the USA since 1980 with projections


The graph below gives information from a 2008 report about consumption of energy in the USA since 1980 with projections until 2030.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

You should write at least 150 words.

Sample Answer 1:

The given bar graph compares the consumption of energy in the USA from 1980 and also gives a projection of it till the year 2030. As is presented in the graph, petrol and oil were the main two sources of energy while the use of coal would increase in the coming years.

As is presented in the line graph, initially in 1980 35 quadrillion units of oil and petrol energy was consumed in the USA while 15-20 quadrillion units each of coal and natural gas was consumed. In this year less than 5 quadrillion energy got from nuclear, solar and hydropower was consumed. The consumption of all of these energy sources kept on increasing with some fluctuations. It is projected that in 2030 the consumption of petrol and oil will reach to over 50 quadrillion units while coal and natural gas’s consumption will reach from 20 to 30 quadrillions. The consumption of nuclear, solar/ wind and hydropower will also increase and would reach to over 5 quadrillion units.

In 2030, oil and petrol would be mostly consumed to get energy while in the second most consumed energy source would be coals.

Model Answer 2:

The supplied line graph depicts information about utilisation of energy in the USA since 1980 with predictions until 2030. In general, petrol & oil and coal accounted as high units of fuel consumption in 1980 and will be increased until 2030. In contrast, nuclear, solar/wind and water power were less favourable fuel consumed since 1980 and will be less chosen until 2030.

Looking at the details, petrol and oil reckoned about 35 quadrillion units in 1980 and was true as the highest fuel use at the time and has gone up gradually to about 40 quadrillions in 2015 and will increase to more than 45 quadrillions in 2030. The same trend is true for coal resources. The coal consumption was about 16 quadrillion units in 1980 and the figure levelled up through the observed years and is projected to hit the figure of 30 quadrillion units in 2030. Natural gas utilisation seemed fluctuated over observed years and it points about 20 quadrillion unit in 2015. However, it is predicted to level off until 2030.

In contrast, nuclear, sun/ wind, and hydropower kept small quantities of fuel consumption compared to other fuel sources as they are projected to a tiny amount of fuel utilisation in 2030. Nuclear use was about 4 quadrillion units in 1980 and in 2030 the figure will hit only about 7 quadrillion units. Solar and hydropower also amassed about 4 quadrillions in 1980 and in 2030, the consumption will be only about 5 quadrillions for solar and hydropower will remain the same figure like it was in 1980.
