The line graph illustrates the amount of energy sources consumed in the USA since 1980, with predicted figure until 2030.
Overall, it is clear that the consumption of all energy sources in the USA witnesses a tremendous leap, except for the figure of hydropower, which is projected to remain relatively constant over the surveyed period. Additionally, petroleum and oil have been the predominant power sources compared to others and are expected to maintain their leading position by 2030.
In 1980, petroleum and oil consumption was the highest among others, with the figure constituting about 35 quadrillion, followed by natural gas at 20 quadrillion and coal at just over 15 quadrillion. Over the following 40 years, there was a notable rise in the figure of petrol and oil, increasing to just under 45 quadrillion. A similar pattern was seen in the amount of coal, whose figure surpassed that of natural gas to become the second largest source of energy, with nearly 25 quadrillion of the total consumption in America. Meanwhile, nuclear and renewable energy sources experienced a modest increase, accounting for approximately 5 quadrillion each.
By 2030, it is predicted that petroleum and oil will remain the primary energy sources in America, reaching a peak of just under 50 quadrillion. Furthermore, the figures for nuclear and renewable sources are also expected to see a growth, but a slower pace, with about 6 quadrillion of nuclear energy and roughly 5 quadrillion of renewable sources, including solar and wind energy by 2030. Conversely, hydropower is projected to remain consistently, maintaining a level of just under 5 quadrillion at the end of the period.
