The image shows a line graph titled "U.S. Energy Consumption by Fuel (1980-2030)" with data from 1980 to 2007 as history and projected data from 2010 to 2030. The graph displays energy consumption in quadrillion units on the y-axis and time in years on the x-axis. Petrol and Oil consumption starts at approximately 35 quadrillion units in 1980, reaching nearly 45 quadrillion units in 2007 and projected to reach over 50 quadrillion units by 2030. Coal consumption begins at just over 15 quadrillion units, increasing to almost 25 quadrillion units in 2007 and projected at 30 quadrillion units in 2030. Natural Gas consumption starts at around 15 quadrillion units, with a steady increase to 25 quadrillion units in 2007 and projected to continue to about 30 quadrillion units in 2030. Nuclear, Solar/Wind, and Hydropower have significantly lower consumption levels, all starting below 5 quadrillion units in 1980. Nuclear energy shows a gradual increase to approximately 8 quadrillion units by 2007, with a projection of nearly 10 quadrillion units by 2030. Solar/Wind energy sees the most significant projected increase, starting at nearly 0 quadrillion units in 1980, with a slight increase to almost 3 quadrillion units in 2007 and an anticipated surge to 10 quadrillion units by 2030. Hydropower consumption remains relatively stable, starting at just over 2 quadrillion units, with little change by 2007 and a small projected increase to about 4 quadrillion units by 2030.

The line graphs demonstrate USA energy use since 1980 and future assumptions till 2020, according to a report done in 2008.
Overall, petrol and oil represent the most consumed energy sources in the USA and are predicted to preserve this rank in the future, all the other resources are predicted to be increased from their 1980 initial values.
To begin with the past statistics, 35 quadrillion units of petrol and oil were consumed in 1980, followed by 20 quadrillion units of coal and just above 15 quadrillion units of natural gas, while nuclear, solar and wind and hydropower fuel were around 4 quadrillion units each, all kept a fluctuating trend except for nuclear powers which kept a steady increase, although their overall ranks maintained approximately the same.
It is predicted that petrol oil and coal will steadily rise reaching 50, 30 quadrillions by 2030, other remaining fuels will maintain stable consumption, the natural gases will be around 25 quadrillions, nuclear will be around 6% exceeding solar wind fuel, and hydropower which are around 5%, 3% respectively.
