The line graph illustrates the USA’s energy consumption, categorized by six energy sources, from 1980, with projections through 2030.
It is evident that petrol and oil have provided the highest amount of the USA’s consumed energy and are expected to continue doing so in the coming years. Moreover, petrol/oil and coal are projected to show an upward trend, while other energy sources are expected to stabilize.
In 1980, coal provided around 15 quadrillion units of the USA’s total energy consumption, whereas natural gas contributed 20 quadrillion units. A decade later, coal overtook natural gas in consumption and became the second most significant energy source. Petrol and oil, which produced 35 quadrillion units at the beginning of the timeframe, are expected to reach nearly 50 quadrillion units by 2030.
Nuclear, solar/wind, and hydropower each produced less than 5 quadrillion units in 1980. Over the following decades, the gap between them widened, with nuclear overtaking the other two. By 2030, the figure for hydropower is expected to stabilize, while nuclear and solar/wind are projected to experience a marginal rise, reaching nearly 7 quadrillion units and 5 quadrillion units, respectively.
