The graph illustrates energy consumption in USA since 1980 to 2030. Information takes from 2008.
Overall, there are six natural resources, and in the first place is Petrol and Oil, from 2005 have a dramatically rise. While others have approximately stable trend. In 1985 Coal and Natural gases intersect with each other and increase to gather to 1990. It is not last intersection in 1995 and 2015 resources already intersect. Last three resources started in the same point and in all period have a stable trend.
In 1980, Petrol and Oil have decline for five years, but after this period fuels have a significantly increase for 35 to 45 quadrillion units. Coal started in 15 and in 1985 intersect with Natural gases, in 1990 to 2015 this two fuels increase to gather, but in 2016 Coal go up and stay in 30. While natural gases have stable trend and in the end stay in 25.
Other three resources do not changes in 50 years and growth maximum only for 3 quadrillion. Always intersect with each other, and stay in initial point.
