This is a print on demand edition of a hard to find publication. The Agricultural Resource Management Survey of corn growers for the year 2005 and the 2008 survey of dry mill ethanol plants are used to estimate the net energy balance of corn ethanol. This report measures all conventional fossil fuel energy used in the production of 1 gallon of corn ethanol. The ratio is about 2.3 BTU of ethanol for 1 BTU of energy inputs, when a portion of total energy input is allocated to byproduct, and fossil fuel is used for processing energy. The ratio is somewhat higher for some firms that are partially substituting biomass energy in processing energy. Charts and tables.

Studies conducted since the late 1970s have estimated the net energy value (NEV) of corn ethanol. However, variations in data and assumptions used among the studies have resulted in a wide range of estimates. This study identifies the factors causing this wide variation and develops a more consistent estimate.

This Element is an excerpt from Crossing the Energy Divide (ISBN: 9780137015443) by Robert U. Ayres and Edward H. Ayres. Available in print and digital formats. Why biofuels won’t work--except for gigantic agribusinesses and their lobbyists. If the entire U.S. corn crop were converted to ethanol, the aggregate reduction in total fossil fuel (gasoline) energy consumption would be just 2.4%. Considering that we still want our corn flakes, pork chops (corn feeds hogs), and cooking oil, any realistic level of crop consumption for fuels would do virtually nothing to end U.S. dependence on foreign oil.
