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 graph compares energy consumption in the USA from 1980 to 2005, with projections up to 2030, for six different fuel sources.
Overall, petrol and oil remain by far the most widely used fuels throughout the period, and their consumption is expected to continue rising. Coal and natural gas are also projected to increase, while the use of nuclear power, solar or wind, and hydropower is predicted to stay relatively low and stable.
In 1980, petrol and oil consumption stood at around 35 quadrillion units, before falling slightly to just under 32 units in 1985. It then rose steadily, reaching roughly 40 units by 2005, and is forecast to climb further to about 47 units by 2030. Coal use started at 16 units and grew gradually to approximately 23 units in 2005, with a sharper rise expected afterwards, reaching nearly 30 units by the end of the period.
Natural gas followed a similar but less pronounced upward trend. Its figure fluctuated around 20 units between 1980 and 2005 and is projected to level off at about 25 units by 2030. In contrast, nuclear, solar/wind and hydropower each remained below 10 units throughout. Nuclear energy increased slightly from about 4 to 7 units, while solar and wind rose slowly from near zero to around 5 units. Hydropower shows almost no change over time and is expected to stay at roughly 4 units in 2030.
