The line graph illustrates the consumption of various energy sources in the United States between 1980 and 2030. Overall, petrol and oil consistently represent the primary energy source, while coal, nuclear, and renewable energy sources show a general upward trend, contrasting with the relative stability of hydropower.
Petrol and oil consumption started at 35 quadrillion units in 1980, dipped slightly, and then climbed steadily to reach 49 quadrillion units by 2030. Coal consumption, which began at 16 quadrillion units, experienced a notable increase, particularly after 1990, and is projected to reach 32 quadrillion units by 2030, surpassing natural gas. Natural gas consumption fluctuated between 17 and 25 quadrillion units, remaining relatively flat after 2020.
In contrast, nuclear energy consumption grew from 3 quadrillion units in 1980 to 8 quadrillion units by 2030. Solar and wind energy also saw a gradual rise, starting at 3 quadrillion units and reaching 6 quadrillion units by the end of the period. Meanwhile, hydropower remained the lowest and most stable source, hovering between 3 and 4 quadrillion units throughout the entire fifty-year timeframe.
