Energy Security
One rationale for ethanol production in the U.S. is increased energy security, from shifting supply from oil imports to domestic sources. Ethanol production requires significant energy, and current U.S. production derives most of that energy from domestic coal, natural gas and other non-oil sources. Because in 2006, 66% of U.S. oil consumption was imported, compared to a net surplus of coal and just 16% of natural gas (2006 figures), the displacement of oil-based fuels to ethanol produced a net shift from foreign to domestic U.S. energy sources.
According to a 2008 analysis by Iowa State University, the growth in U.S. ethanol fuel production caused retail gasoline prices to be 29–40 cents per gallon lower than would otherwise have been the case. The U.S. consumed 138.2×109 US gal (523×106 m3) of gasoline in 2008, blended with about 9.6×109 US gal (36×106 m3) of ethanol, representing a market share of almost 7% of supply by volume. Given its lower energy content, ethanol fuel displaced about 6.4×109 US gal (24×106 m3) of gasoline, representing 4.6 percent in equivalent energy units.

Famous quotes containing the words energy and/or security:
“Three elements go to make up an idea. The first is its intrinsic quality as a feeling. The second is the energy with which it affects other ideas, an energy which is infinite in the here-and-nowness of immediate sensation, finite and relative in the recency of the past. The third element is the tendency of an idea to bring along other ideas with it.”
—Charles Sanders Peirce (1839–1914)
“I feel a sincere wish indeed to see our government brought back to it’s republican principles, to see that kind of government firmly fixed, to which my whole life has been devoted. I hope we shall now see it so established, as that when I retire, it may be under full security that we are to continue free and happy.”
—Thomas Jefferson (1743–1826)
