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

The graph shows data from 1980 with forecasts up to 2030 on the US population’s

energy

consumption. Generally, in 1980, petrol and

oil

were the dominant

energy

sources,

while

nuclear, solar, wind and

hydropower

were the least utilized fuels.

Additionally

, in 2030, gasoline and

oil

are forecasted to remain the leading sources of

energy

,

whereas

hydropower

is predicted to take the bottom-most position. Over a 28-year period, starting

1980, petrol and

oil

rose in consumption from 35

quadrillion

units

to about 40

quadrillion

units

. Coal and natural gas performed

similarly

, as both increased from around 17

quadrillion

units

and 20

quadrillion

units

, respectively, to about 23

quadrillion

units

. During the same period, nuclear

energy

gradually climbed from nearly three

quadrillion

units

to seven

quadrillion

units

,

while

solar, wind and

hydropower

fuels remained static at approximately three

quadrillion

units

. Over the duration of the forecasts, ranging from 2008 to 2030, petrol and

oil

consumption are expected to elevate up to nearly 48

quadrillion

units

. Coal and natural gas are estimated to increase up to about 32

quadrillion

units

and 25

quadrillion

units

, respectively.

Finally

, nuclear, solar, wind, and

hydropower

energy

will stay nearly constant throughout the projected period.
