The line chart details fuel consumption from 1980 to 2030 in the United States.
Overall, petrol and oil have been and will continue to be the dominant fuel sources, followed by coal and natural gas, and more distantly by renewable energies. The consumption of all varieties of fuel has increased and is expected to continue rising, with the exception of hydropower, which will remain stable overall.
Regarding the consumption of fossil fuels, petrol and oil consumption stood at 35 quadrillion units in 1980. After a slight dip with minor fluctuations around 33 quadrillion units until approximately 2000, a steadier rise begins that is anticipated to reach nearly 50 quadrillion by 2030, by far the greatest data point in the chart. By comparison, the consumption of coal and natural gas was considerably lower and displayed broadly similar trends. The energy generated by natural gas began the period at 20 quadrillion units, and coal was 4 quadrillion lower. Over the following years, the figures were erratic and their relative positions in the chart switched several times until coal began to separate itself around 2015, predicted to finish around 8 quadrillion units higher than natural gas at 30 quadrillion.
Shifting to cleaner energy sources, the consumption of these fuels was less significant, each with a beginning data count of 4 quadrillion units. In the years that ensued, the consumption of nuclear power grew the strongest to just over 6 quadrillion by the end of the projections. Solar and wind power will register a slightly lower quantity, at near 5 quadrillion, while hydropower is expected to experience minor fluctuations to finish around 4 quadrillion units.
