Energy Balance/Life Cycle Inventory for Ethanol:
Minnesota Department of Agriculture
"The concept of 'input efficiencies for fossil energy sources' was introduced as a component of the study. This was meant to account for the fossil energy used to extract, transport and manufacture the raw material (crude oil) into the final energy product (gasoline). According to the study, gasoline has an energy ratio of 0.805. In other words, for every unit of energy dedicated to the production of gasoline there is a 19.5 percent energy loss."
