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 the usage of energy by six fuels in the UAS from 1980 to the projections of 2030 in a 2008 report. Units have been measured in

However

while

the use of three was approximately 3

has kept steadily rising to about 8

By contrast

Overall

Nevertheless
