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 shows how energy consumption by fuel in the USA changed from 1980, with predictions for 2030.
It is clear from the graph that despite a slight drop in the first five years, energy consumption from petrol and oil increased dramatically from 35 quadrillion units in 1980 to about 40 quadrillion in 2008, and it was predicted to continue on the upward trend, reaching about 50 quadrillion by 2030.
A similar increasing trend was also seen in coal, with the figure increasing from just over 15 quadrillion units to 25 quadrillion units between 1980 and 2008, after which it was predicted to rise to 30 quadrillion units in 2030. From 1980 to 2008, energy consumption from natural gas increased as well, rising from 20 quadrillion units to 25 quadrillion units. However, it was predicted to remain relatively unchanged afterwards.
In comparison, the consumption of energy from nuclear, solar/wind and hydropower remained relatively stable, all of which leveled off at just below 5 quadrillion units between 1980 and 2008. After that, the figure for nuclear and solar/wind was predicted to increase slightly, while for hydropower, the level-off was predicted to continue.
Overall, the US used petrol and oil as its dominant fuel source, and the situation was predicted to continue in the future. The status of clean energy sources, including nuclear, solar/wind and hydropower, maintained and was predicted to remain insignificant and unchanged.
