I tried researching oil used for farming in the United States. Agriculture oil use isn’t enough for the US Department of Energy to track separately. All energy used in the USA such as Natural Gas, Electricity, Gasoline, Diesel, LP, etc plus all the energy inputs for farm chemicals such as fertilizers came to farming using 2% total of the energy produced in America.
How much of a drop you think we would see in price?
That's total energy. Includes electricity and propane etc. We're talking about how much gasoline is used for producing ethanol. That would be about 4.8 percent of US gasoline consumption in 2007.
If we stopped wasting gasoline to produce ethanol we would save a lot of money since, according to a 2005 report issued by the Agriculture Department, corn ethanol costs an average of $2.53 to produce, or several times what it costs to produce a gallon of gasoline. That doesn't leave much room for taxes or profits.
