The graph below gives information from a 2008 report about consumption of energy in the USA since 1980 with projections until 2030

The line graph illustrates how energy sources were spent from 1980 and 2008 and they will be spent over the period of 22 years in the United States. Units are measured in quadrillions. Looking from an

overall

perspective, it is readily apparent that using of petrol&oil, coal, and natural gas has increased from the beginning of the time to 2008 and it is expected to continue to rise until 2030.

In contrast

, nuclear, solar/wind, and hydropower energies were consumed steadily until 2008 and it is predicted to be the same until the end of the period in question. In the first year, 1980, consumption of nuclear, solar/wind, and hydropower sources stood at approximately 4 and they roughly stayed steady over the span in the question. It is

also

a notable trend that fossil fuels were the most consumed energy sources among these six. The usage of petrol/oil was 35

initially

and

then

it climbed dramatically. After 2008, it is estimated that the upward trend will continue. Coal and natural gas usage

also

have similar figures but gas consumption is estimated to level off in 2015 at 25 quadrillions.
