An acre of corn will yield roughly 5,500 dry pounds of stover, enough to produce about 180 gallons of ethanol" (Baker & Zanier 2006). But once again, such intensive farming methods could result in depletion of the soil and ultimately hamper the fertility of the soil, given that corn stover is usually left on fields to minimize erosion. Ideally, the creation of new technology would improve productivity without hampering

4). Likewise, in the same article, Kay Martin of the Ventura County, California public works agency is quoted as saying, "From a macroeconomics or macro-environmental perspective, it just makes sense." The need to build an infrastructure for production of bio-fuels creates economic opportunities. Of course, not everybody is so enthusiastic. To grow corn, diesel tractors are required to plant, fertilize and harvest it with substantial coal-fired electricity needed for the

In addition, large quantities of natural gas are required to produce fertilizers which are needed for growing corn. It is estimated that an average of 135 pounds of nitrogen (a potent-greenhouse-gas) per acre is used in growing corn in most U.S. farms. Besides, research by the U.S. Department for Agriculture (USDA) shows that tilled soil releases carbon dioxide gas into the atmosphere in proportion to the volume of soil

This helps to establish the case that a gap exists between that which science accepts about biofuels and that which politicians present on the subject. This is complimented by Thornton's (2006) concise detraction of ethanol, this article serves as reinforcement for the recurring case that the process of yielding energy from ethanol is too consuming of time and energy, and thus, should be disregarded as a means to developing an

For an industry that is fast becoming a verifiable and sustainable model of energy development, the labor that supplies the demand will likely get its fair share of attention (Goldemberg, 2007). On the marketing end of the industry, there is the automobile manufacturing boom of flex cars, and the new multi-billion dollar deals between the largest ethanol producer in Brazil, Cosan Limited, and Royal Dutch Shell. The most recent joint
