Fuel ethanol (10-15% of US gasoline content) is derived from corn and adds approximately 10-15% volume to gasoline supply, but ethanol has a lower heat content per gallon than gasoline, so cars filled with ethanol-blended fuel do not travel as far as cars filled with pure gasoline, reducing the net liquid fuel available for transportation.

“Ethanol also has a lower heat content per gallon... you fill up your tank with 15% ethanol and your car doesn't go as far as if you've filled it up with 100% gasoline.”
