We are considering adding ethanol to our current gasoline formulae, but doing so will only improve our miles per gallon and, of course, produce much cleaner byproducts. Ethanol turns into a transient,repair, at most. Will using ethanol keep the price below what we already pay for gasoline? Other crops, such soybeans, sugar beets, raw sugarcane, etc., can also be used to produce ethanol fuel. It doesn't necessarily follow that this will happen, but if no complementary renewable energy fuels are created, such as hydrogen-based fuel cells to support the ethanol fuel method, this might lead to shortages of several important food staples. Granted, the extremely big south American nation of Brazil has been implementing its ethanol program for for ten years, with largely positive outcomes, and has benefited from the transition away from foreign oil.
