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

What has been depicted in the line graph is the consumption of energy in the United States in 1980,

along with

future projections for 2030.

Overall

, throughout the whole time frame, petrol and oil had the highest portion among the other consumed energy,

whereas

that of hydropower was the lowest. From 1990 to 2020, petrol and oil showed a rising trend, ranging from 35

quadrillion

to 45

quadrillion

, and it is estimated that it will increase 50

quadrillion

at the end

of the period.

Moreover

, at the beginning of the period, coal and natural gas followed an almost similar pattern, starting at 20 and 16 quadrillions respectively, and finishing at around 25 quadrillions in 2020.

In addition

, it is predicted that the former will continue its trend, which is nearly 30

quadrillion

,

while

the latter will remain unchanged at 25

quadrillion

. Over the given period, nuclear, solar/wind, and hydropower started at around 4

quadrillion

, with nuclear at the top, followed by solar and wind at around 5

quadrillion

in 2010. Both are projected to reach around 6 and 9

quadrillion

by 2030 in order,

while

hydropower experienced a slight drop and it is projected that it will fall below the initial values.
