New research due out soon from the University of Nebraska-Lincoln finds that ethanol may be two to three times more energy efficient than previously thought. The study says that 1.5 to 1.6 more units of energy are found in the ethanol than are required by the production process. And if you're looking at just the fossil fuel inputs, the study finds that 13 gallons of ethanol are created for every 1 gallon of petroleum used in the lifecycle of the corn-ethanol production process. That's a pretty good return on investment!
