. . . To compare the energy efficiency and environmental impacts of corn production and processing for food and for biofuel, the researchers inventoried the resources required for corn production and processing, then determined the economic and environmental impact of using these resources – all defined in terms of energy available and expended, and normalized to cost in U.S. dollars.A big gain versus a net loss? Gasohol has been a bipartisan boondoggle, and it's time to end it.
“There are a lot of abstract concepts to contend with when discussing human-induced effects in the critical zone in agricultural areas,” Richardson said. “We want to present it in a way that will show the equivalent dollar value of the human energy expended in agricultural production and how much we gain when corn is used as food versus biofuel.”
Kumar and Richardson accounted for numerous factors in their analysis, including assessing the energy required to prepare and maintain the landscape for agricultural production for corn and its conversion to biofuel. Then, they quantified the environmental benefits and impacts in terms of critical zone services, representing the effects on the atmosphere, water quality and corn’s societal value, both as food and fuel.
In monetary terms, their results show that the net social and economic worth of food corn production in the U.S. is $1,492 per hectare, versus a $10 per hectare loss for biofuel corn production.
