This book evaluates maize as a bioenergy fuel source from two perspectives. It explores whether the input energy needed to generate fuel significantly exceeded by the energy harvested. In examining this issue, the chapters provide assessments of the social, economic, and political impact on fuel pricing, food costs, and the environmental challenge with corn biomass the engine of change. It then examines whether corn be genetically improved so that its biomass is significantly increased, its cellulose-lignin complex made more amenable to harvesting and to processing, and grown in regions not normally associated with its cultivation of food.
