This is an article posted by Jim Motavalli, who is the author of Forward Drive: The Race to Build Clean Cars for the Future, which discusses the viability of corn ethanol as a reasonable substitute for petroleum based fuels, both in thirty years and in one hundred years. The author of this article states that according to the Energy Independence and Security Act (EISA), 36 billion gallons of corn ethanol and biodiesel will be produced in the United States by 2022. Even with this large amount of biofuel production, environmentalists, like the Sierra Nevada Club, do not find corn ethanol as a viable source due to the high level of greenhouse emissions released during its production. According to an EPA study, in thirty years corn ethanol could actually increase greenhouse emissions by five percent. The general statement of this article is that corn ethanol is not yet ready for mass production.
