Energy bill mandating 36 billion
Gasoline containing up to 10% ethanol began a decades-long growth in the United States in the late 1970s.The demand for ethanol produced from field corn was spurred by the discovery that methyl tertiary butyl ether (MTBE) was contaminating groundwater.Ethanol production was expected to continue to grow over the next several years, since the Energy Independence and Security Act of 2007 required 36 billion US gallons of renewable fuel use by 2022.The target for ethanol production from cellulosic feedstocks was 16 billion US gallons a year.Bottom left: the bright yellow gas cap used in newer models.E85 Flexfuel badging used in newer models from Chrysler (top right), Ford (middle right) and GM (bottom right).
By early 2013 there were around 11 million E85-capable vehicles on U. Like the limitations suffered by sales of E85, commercialization of E15 is constrained by the lack of infrastructure as most fuel stations do not have enough pumps to offer the new E15 blend, few existing pumps are certified to dispense E15, and no dedicated tanks are readily available to store E15.
Motorists drove less, gasoline prices dropped sharply, capacity rose and less financing was available. In 1826 Samuel Morey experimented with an internal combustion chemical mixture that used ethanol (combined with turpentine and ambient air then vaporized) as fuel.
At the time, his discovery was overlooked, mostly due to the success of steam power.
In December 2010 several groups, including the Alliance of Automobile Manufacturers, the American Petroleum Institute, the Association of International Automobile Manufacturers, the National Marine Manufacturers Association, the Outdoor Power Equipment Institute, and the Grocery Manufacturers Association, filed suit against the EPA in the United States Court of Appeals for the District of Columbia Circuit.
According to a survey conducted by the American Automobile Association (AAA) in 2012, only about 12 million out of the more than 240 million light-duty vehicles on the U. roads in 2012 are approved by manufacturers are fully compliant with E15 gasoline.
