The graph below gives information from a 2008 report about consumption ofenergy in the USA since 1980 with projections until 2030. Summarise the information by selecting and reporting the main features, andmake comparisons where relevant.
The line graph illustrates changes in the energy exhausted by six different energy sources in the US during the given 50 years.
It is clear that non-renewable and renewable sources show an increasing trend on energy consumption.
Specifically, in 1980, petrol and oil ranked first, with 35 quadrillion units, followed by natural gas (20 quadrillion units). Coal came at the bottom of the list, with approximately 16 quadrillion units.In the following years,energy used up by petrol and oil and coal trend to experience the same rising tendency steadily in the following decades to 46 and 27 quadrillion units respectively.However coal’s energy consumption remains stable about 24 quadrillion units from 2015 to 2030 by expectation.
Differently,for renewable sources, all three sources consumed the same energy which is 4 quadrillion units in 1980. Similarly,the energy consumption by nuclear and solar/wind climbed slightly over the next decades which is expected to below 10 quadrillion units.But hydropower is predicted to maintain stable at 3 quadrillion units after a mildly decreasing.
