'''Gasoline''' or '''gas''' is a [[fuel]] derived from [[petroleum]], which is in turn derived from ancient [[vegetable]] matter and [[dinosaur]]s, if you believe in that sort of thing.  Gasoline is an aliphatic hydrocarbon, or the molecules are composed of nothing but hydrogen and carbon in long chains.  The energy contained in a gallon of gasoline is approximately 132X10<sup>6</sup> joules of [[energy]], equivalent to 125,000 [[BTU]] or 36,650 [[watt-hours]]. <ref> US Department of Energy [http://cta.ornl.gov/data/appendix_b.shtml]</ref>  This high energy density allows for much of the modern industry and comforts of the modern world through the [[transportation]] of goods and people.

<br>Gasoline is refined from [[crude oil]] via [[distillation]].  Gasoline is sold at gas or fueling stations where it is pumped into [[vehicle]]s.  According to national figures from the U.S. Department of Energy, in May 2007, 46% of the cost of gasoline went to pay for crude oil, 28% for refining, 13% to taxes, and 13% for distribution and marketing<ref>Energy Information Administration [http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp]</ref>.  While Prices have risen to new highs, in [[inflation|inflationary]] terms, gas prices are still lower than during the 1973 [[Oil Crisis|Oil Crisies]] or 1979 Energy Crisis.  It is illegal to pump your own gas in [[Oregon]].
