The energy consumption by fuel(1980-2030) The line chart presents a statistics of energy consumption in the USA from 1980 to 2014 and a relevant projection before 2030. The consumption of petrol and oil dominated throughout the period, which was 35 quadrillion units in 1980, followed by a decrease of 4 quadrillion units by 1985. After that, its data rose up to slightly over 40 quadrillion units by 2014, although there was a fluctuation from 1985 to 2014. It is predicted to shoot up to approximately 47 in the following 16 years. The consumption of coal and natural gas changed similarly between 1980 and 2014, which were 16 and 20 quadrillion units respectively in 1980, both increasing to just over 25 quadrillion units by 2014. Coal is estimated to increase rapidly to over 30 quadrillion units by 2030, while natural gas will remain stable at 25 quadrillion units. In 1980, the amount of using nuclear, solar/wind and hydropower all stayed at 4 quadrillion units. Then, there was an upward trend for nuclear and solar/wind, with the data increasing to 7 and 5 respectively. Both of them are expected to stay at the same levels until 2025, when they start to rise again. While the figure of hydropower dropped back to 4 quadrillion units after several increases, which is expected to stay at this level before 2030. Overall, the USA rely on petrol and oil heavily not only in the past, but also in future. While is use of nuclear, solar/wind and hydropower seems relevantly insignificant.
