Many large farms in the Midwest have planted all or part of their land area to take advantage of the government subsidies which are offered for corn production to supply the ethanol production needs.
Greenhouse gas emission: While ethanol use is beneficial for the environment, an article in BioScience suggests that the greenhouse gasses emitted during production of the fuel cancels out that effect.
Some experts feel that emissions caused by the use of petroleum-based fuels to farm the corn and produce the ethanol may be greater than the emissions saved using ethanol as an alternative fuel.
Reduces air pollution: Ethanol reduces the amount of carbon monoxide and other ground-level toxic air pollutants as compared to conventional unleaded gasoline by about 10 to 30 percent.
Some of these studies base their findings on ethanol, a biofuel made from corn, and declare that biofuels will be too expensive and come at a cost to the world food supply.
Aviation grade ethanol, (AGE-85) is an 85 percent ethanol blended fuel that is beginning to replace 100 octane low lead aviation gasoline, which has been the standard fuel for reciprocating engine aircraft since World War II.
Sustainability: According to the Union of Concerned Scientists, many of the crops grown for ethanol are not done so in a sustainable manner, resulting in habitat destruction and loss of valuable food supply resources.
When people purchase vehicles that run on ethanol, who will make sure there are adequate ethanol pumps or service stations so that the drivers of these energy-efficient cars will be able to refuel?
Indiana, the state that has marketed the country's first soybean oil candles, desires to get enough signatures on a petition in order to move Indiana forward in ethanol and soybean production.
American ethanol policies do not "kill" the poor, but they do drive up corn prices.
