Every gallon of corn-derived alcohol sold in motor fuel is two-thirds of a gallon of gasoline that the oil companies don’t sell. Do they like this?
Corn states love alcohol in fuel because it drives up corn prices.
Beef states hate higher feed prices.
Hydrofracking has raised U.S. production of oil and gas, reducing concern over energy independence and cutting incentive to add alcohol to gasoline.
The U.N. has asked the U.S. to suspend its use of corn to power automobiles as it drives up world food prices, especially in this drought year.
Many ask why government should subsidize the ethanol industry.
GREED.. some podunk corn squeezin jerk will make a few bucks, bedammed with everybody else , who cares if your car blows up .Why add a product that isn't needed, reduces mileage drastically, and can harm your vehicle? Plus it drives up the prices of almost every product made in the US, from cereal to beef to chicken to just about all groceries.
