In Brazil where sugar cane is used, the yield is higher, and conversion to ethanol is more energy efficient than corn. Recent developments with cellulosic ethanol production may improve yields even further. [12] In 2006 a study from the University of Minnesota found that corn-grain ethanol produced 1.25 units of energy per unit put in. [13]
The dominant ethanol feedstock in warmer regions is sugarcane. [8] In temperate regions, corn or sugar beets are used. [8] [9] In the United States, the main feedstock for the production of ethanol is currently corn. [8] Approximately 2.8 gallons of ethanol are produced from one bushel of corn (0.42 liter per kilogram).
For instance, a separate survey reports that production of ethanol from sugarcane, which requires a tropical climate to grow productively, returns from 8 to 9 units of energy for each unit expended, as compared to corn, which only returns about 1.34 units of fuel energy for each unit of energy expended. [69]
U.S. sugarcane production occurs in Florida, Louisiana, Hawaii, and Texas. The first three plants to produce sugarcane-based ethanol went online in Louisiana in mid-2009. Sugar mills in Lacassine, St. James and Bunkie were converted to sugarcane ethanol production using Colombian technology to enable
Regarding social responsibility the ethanol production sector maintains more than 600 schools, 200 nursery centers and 300 day care units, as legislation requires that 1% of the net sugar cane price and 2% of the net ethanol price must be devoted to medical, dental, pharmaceutical, sanitary, and educational services for sugar cane workers. In ...
Mechanized harvesting of sugarcane (Saccharum officinarum), Piracicaba, São Paulo.. The history of ethanol fuel in Brazil dates from the 1970s and relates to Brazil's sugarcane-based ethanol fuel program, which allowed the country to become the world's second largest producer of ethanol, and the world's largest exporter.

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
In line with the observations in Japan, hydrous ethanol is known to be less corrosive than anhydrous ethanol. The reaction mechanism is 3 EtOH + Al -> Al(OEt) 3 + 3 ⁄ 2 H 2 at lower-mid blends. When enough water is present in the fuel, aluminum will react preferably with water to produce Al 2 O 3 , repairing the protective aluminum oxide layer.
