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 shows how much energy is used in terms of six fuel categories in the USA between 1980 and 2030.

Overall

,

it is clear that

the

consumption

of petrol and oil stands first during the period.

In addition

, the

figure

for

consumption

of coal and natural

gas

increased,

while

that of hydropower remained constant. In 1980, the

figure

for usage of petrol and oil ranked first with 35

quadrillion

units

,

while

that of nuclear, solar or wind and hydropower stood

last

with less than 5

quadrillion

units

.

Although

the

figure

for natural

gas

was higher than coal at the beginning of the period with 20 and 15

quadrillion

units

respectively, the

figure

for

consumption

of coal overtook that for natural

gas

in 1990. It is noteworthy that the

figure

for petrol and oil increased significantly and it is expected to rise after 2020 to reach its peak at 50

quadrillion

units

. The

figure

for natural

gas

experienced some fluctuations almost before 2020 and after that, it is predicted to remain at its level at 25

quadrillion

units

.

Additionally

, the

figure

for coal showed a substantial rise before 2020 and it will continue its growth to reach 30

quadrillion

units

. It is noteworthy that, the

consumption

of nuclear and solar or wind energy rose slightly to almost 10

quadrillion

units

in the first 20 years, and it is predicted to pursue their upward trend.

Moreover

, the

figure

for hydropower remained stable at approximately 4

quadrillion

units

, and after 2020, it will not be changed.
