Despite the controversy, in order to adjust to EPA regulations, 2012 and 2013 model year vehicles manufactured by General Motors can use fuel containing up to 15 percent ethanol, as indicated in the vehicle owners' manuals. However, the carmaker warned that for model year 2011 or earlier vehicles, they "strongly recommend that GM customers ...
The ethanol program is controversial for several reasons, not the least of which was that the ethanol industry was dominated by one company – Archer Daniels Midland of Peoria, Ill. In 1984, the number of ethanol plants peaked at 163 in the U.S., producing 595 million US gallons (2,250,000 m 3) of ethanol that year.
In 2000, Dr. Michael Wang, of Argonne National Laboratory, wrote that these ethanol by-products are the most contentious issue in evaluating the energy balance of ethanol. He wrote that Pimentel assumes that corn ethanol entirely replaces gasoline and so the quantity of by-products is too large for the market to absorb, and they become waste.
Since the 1970s, the U.S. has subsidized ethanol produced from food crops, especially from corn, thus providing a homegrown, alternative fuel source for our automobiles. But for multiple reasons ...
The production of fuel ethanol from corn in the United States is controversial for a few reasons. Production of ethanol from corn is 5 to 6 times less efficient than producing it from sugarcane. The reason that corn has been notoriously used for ethanol production is because farmers are either paid to destroy crops or to not grow corn crops.
Midwest floods, the rise of corn ethanol, and an increase in food exports to Europe have all driven the cost of grain upward. At the same time, increases in the price of gas have also made it more ...
Corn is the main feedstock used for producing ethanol fuel in the United States. Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States, mandated to be blended with gasoline in the Renewable Fuel Standard. Corn ethanol is produced by ethanol fermentation and distillation.
Alcohol (from Arabic al-kuḥl 'the kohl'), [11] sometimes referred to by the chemical name ethanol, is the second most consumed psychoactive drug globally behind caffeine. [12] Alcohol is a central nervous system (CNS) depressant , decreasing electrical activity of neurons in the brain. [ 13 ]
