Bài IELTS Task 1, Cambridge 9- Trend in energy consumption in the USA

Question

Answer: 

The graph demonstrates a 2008 report of engergy consumption in the USA since 1980 with projections until 2030. 

It is clear that the level of power consumption in the USA has increased since 1980 and this trend is expected to continue until the end of the report period. Overall, the much larger amount of petrol and oil was used in comparison with coal, gas and other alternative energy sources, and consumption of petrol and oil experienced the fastest rising movement with the similar trend projected till 2030.

In 1980, petrol and oil consumption was 35 quatrillion units. The usage amount of coal and gas was lower, at 16 and 20 quatrillion units respectively. Nuclear, solar and wind and hydropower experienced the same level of consumption at just 4 quatrillion units. From 1980 to 2008, there were wavering rising trend among all of these types of power. In 2008, level of petrol and gas used doubled that of coal and natural engergy and was sixfold higher than that of the other alternative resources.

From 2008 to 2030, the usage of petrol, gas and coal are expected to continue its upward trend with more consistency, reaching under 50 and 27 at the end of the period. Having started to level off since 2013, natural gas consumption will remain at about 24 by 2030. Nuclear and solar/wind power will experience a slight increase to reach 7 and 5 respectively, whereas hydropower will see a slight decline until bottom up at 4 in the final year.
