2. Modern Production of Ethanol - Energy Resourcefulness
Webenergy value of corn ethanol has become positive in recent years due to technologi-cal advances in ethanol conversion and increased efficiency in farm production. We show that corn ethanol is energy efficient as indicated by an energy ratio of 1.24. Keywords: Ethanol, net energy balance, corn production, energy security Yes. If we sum the energy needed for production of corn and ethanol conversion and distribution processes we end up with a total expenditure of 68,206BTUs/gal. A gallon of ethanol contains 76,300BTUs/gal and we therefore get an energy ratio of 1.12. This number could be even higher if we incorporated co-products, for … See more Ethanol has been proposed as a substitute for gasoline in order to move the country away from using fossil fuels. Ethanol is said to be much cleaner than other forms of fuels however, it … See more The majority of energy consumed during the production of ethanol comes from production of the corn..
