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

The line graph shows a 2008 study on US

energy

consumption since 1980 with predictions until 2030. Units are measured in

quadrillions

.

Overall

, it is evident that

petrol

and

oil

were the categories that consumed the highest

energy

from the past till the future.

Whereas

hydropower remains insignificant throughout the period. In 1980

petrol

and

oil

recorded the largest use of power in the USA with, 35 quadrillion units. Natural

gas

and coal are followed by 20

quadrillions

and around 16

quadrillions

respectively. Nuclear, solar/wind and hydropower were the categories which utilized the least significant amount of

energy

, accounting for figures below 5

quadrillions

each.

Energy

utilization of

petrol

and

oil

fluctuates for some years after which it began to grow gradually. By 2030, it is foreseen that

petrol

and

oil

will continue to lead USA

energy

utilization with around 50 quadrillion units.

Furthermore

, coal and natural

gas

expenditures of power

also

varied for a

while

. It is projected that coal use of

energy

will increase

whereas

natural

gas

energy

expenditure will remain static. By 2030 coal will be the second highest

energy

consumption with approximately 25 quadrillion and natural

gas

will followed. The least significant group which were Nuclear, solar/wind and hydropower recorded a constant figure for years. In the

future

all these 3 groups are predicted to use around 5

quadrillions

or less each.
