The graph represents the six different types of energies (petrol and oil, coal, natural gas, nuclear, solar/wind and hydropower) used in the US from 1980 to 2008 and the prediction to 2030.
Overall, all the energy consumption has been increasing constantly especially with petrol and oil are expected to be remained with dominant usages in the USA while alternative energy sources (nuclear, solar/wind and hydropower) have showed the incremental trend but the prediction is recorded at the same level.
Petrol and oil was the common energy sources in the US in 1980 as this consumption was recorded at 35 quadrillion units (q) and this usage continued to increase despite the periodic fluctuation in 1985 and 1995, to reach at about 40 q by 2008.
In contrast, coal and natural gas were the next commonly used energy sources which had 20q and 15q respectively in the year of 1980 which usage increased steadily to record at about 22q for both in 2008. Meanwhile, the lowest energy sources were the alternative energy sources and it started at approximately 4q usages growing to close to 5q by 2008.
From 2008 and onward, the petrol and oil will be remained the same at its dominance usages of over 50q, coal will be increased with its usage to 30q and the prediction for natural gas is remained unchanged at 25q until 2030. Similarly, nuclear, solar/wind and hydropower are expected to have the same usage as those of 2008 (of 5q).
