The line graph below shows the US energy consumption by fuel from 1980 to 2008 and projections until 2030.
Overall, fossil fuel (petrol, oil, coal and natural gas) accounted for the largest proportion of the US energy consumption between 1980 and 2008 and it is anticipated that these energy sources will dominate the consumption of energy in the US till 2030. Meanwhile, kinds of renewable energy (nuclear power, solar/wind power and hydropower) will only contribute to minority of the US energy consumption until 2030.
As can be seen clearly from the graph, the consumption of energy in the US from Petrol and oil saw a fluctuation at around 35 quadrillion units over this span of 15 years (1980-1995), then increased slightly to estimated 42 quadrillion units from 1995 to 2008, and this figure will grow gradually to 2030 at about 50 quadrillion units, will still accounting for the largest contribution of the US energy consumption. At the same patterns, the consumption of energy from coal and natural gas will also rise gradually to 2030 at 30 and 20 quadrillion units respectively.
On the other hand, nuclear power, solar/wind power and hydropower only made up about 4 quadrillion units each in 1980 but nuclear power and solar/wind power witnessed a slowly upward trend and this trend will go on till 2030 at 8 and 7 quadrillion units respectively, while hydropower remained the figure in 1980 and this will happen until 2030.
