Alcohol (also known as ethanol) has a number of effects on health. Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, with increased risk of several types of cancer and alcohol use disorder. [1]
Sugarcane ethanol has an energy balance seven times greater than corn ethanol. [101] As of 2007, Brazilian distiller production costs were 22 cents per liter, compared with 30 cents per liter for corn-based ethanol. [102] Corn-derived ethanol costs 30% more because the corn starch must first be converted to sugar before distillation into ...
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.
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 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.
Another serious problem with corn ethanol as a replacement for gasoline, is the engine damage on standard vehicles. E10 contains ten percent ethanol and is acceptable for most vehicles on the road today, while E15 contains fifteen percent ethanol and is usually prohibited for cars built before 2001. [5]

The level of ethanol consumption that minimizes the risk of disease, injury, and death is subject to some controversy. [16] Several studies have found a J-shaped relationship between alcohol consumption and health, [17] [18] [2] [19] meaning that risk is minimized at a certain (non-zero) consumption level, and drinking below or above this level increases risk, with the risk level of drinking a ...
