The graph below illustrates the utilization of energy resources in the United States from 1980 to 2008, along with predictions extending to 2030.
Petroleum and oil are the most consumed fuel resources in the U.S., experiencing consistent growth over the years. Coal and natural gas serve as secondary fuel resources for American citizens, while nuclear, solar, and hydropower are the least consumed compared to the others.
In 1980, petroleum and oil had a consumption level of 35. This figure fluctuated between 30 and 35 from 1980 to 2000. However, a significant increase in consumption occurred after 2000, with predictions suggesting a rise to nearly 50 by 2030.
Natural gas and coal are the secondary fuel resources in the United States. Natural gas had a consumption level of 20 in 1980, and after fluctuating for two decades, its demand increased to 25 after 2000, remaining stable thereafter. It is forecasted to remain constant through 2030. In contrast, coal started at 20 in 1980, but its consumption has steadily increased, with predictions indicating it could reach close to 30 by 2030.
Other forms of energy, such as nuclear, solar, and hydropower, are less consumed overall. Their consumption was recorded at 5 in 1980, showing only a slight increase in the following years. By 2030, it is predicted that their consumption will remain below 10, with hydropower usage expected to remain constant at around 2.5 from 2010 to 2030
