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:
“All my energy and attention were devoted to trying to help her solve her problems. Unfortunately I didn’t have much success.”
—Arthur Miller (b. 1915)
“Is a Bill of Rights a security for [religious liberty]? If there were but one sect in America, a Bill of Rights would be a small protection for liberty.... Freedom derives from a multiplicity of sects, which pervade America, and which is the best and only security for religious liberty in any society. For where there is such a variety of sects, there cannot be a majority of any one sect to oppress and persecute the rest.”
—James Madison (1751–1836)
