The United States is in the midst of an energy crisis. The U.S. imports the majority of its fossil fuel petroleum products from overseas. The Department of Energy estimates that by 2010 the U.S. will import 75% of its required transportation fuels (Lauder, 2001). These petroleum-based fuels are not a limitless resource. At this time based on 2005 consumption rates of petroleum products, “the world has 41 years of proven reserves” (Dimotakis, Grober and Lewis, p. 5). Experts state that petroleum based exploration, discoveries and drilling will reach their peak by 2050. Increased awareness of the limits and over dependence on petroleum-based fossil fuels has led to a re-emergence of alternative fuels. The U.S. government has implemented an alternative energy initiative as part of their overall energy policy since the early 1970’s. This new policy came because of the 1973 oil embargo. These alternative energy initiatives have focused primarily on bio-fuel sources. The two leading bio-fuel alternatives to the current petroleum-based fuels are bio-diesel and ethanol. “Driven by environmental, economic, and energy security concerns, the availability of ethanol (E85) is growing nationally” (U.S. Department of Energy, 2006). This evaluation judges if ethanol is the most promising bio-fuel to reduce the United States dependency on fossil fuels economically, practically, technically, and environmentally.

Chapter Summaries
Introduction: This introductory section sets the stage by highlighting the US energy crisis and its dependence on foreign oil. It introduces biofuels, specifically ethanol and biodiesel, as potential alternatives and frames the paper's central question: Is ethanol the answer to America's energy crisis? The section emphasizes the need to assess ethanol's economic, practical, technical, and environmental viability.
Economic Aspects of Ethanol: This section explores the economic benefits and drawbacks of ethanol. While ethanol production boosts rural economies and offers potential cost savings compared to rising gasoline prices, it faces challenges such as price volatility tied to corn prices and the need for substantial government subsidies to remain competitive with gasoline. The reliance on corn as a primary source also raises concerns about food versus fuel debates and potential impacts on food prices, particularly impacting countries like Mexico. The chapter concludes by acknowledging that ethanol's economic viability depends heavily on efficient production, distribution, and stable corn prices.
Practical Aspects of Ethanol: This section examines the practical challenges and opportunities for widespread ethanol adoption. The limited current distribution infrastructure, primarily concentrated in the Midwest, hinders nationwide use. The incompatibility of ethanol with existing petroleum pipelines presents a major hurdle. However, growing public support, government initiatives like the "20 in 10" plan, and the involvement of major auto manufacturers promoting flexible-fuel vehicles indicate a movement towards improved viability and distribution. The section highlights ongoing efforts to develop compatible pipeline systems and expand ethanol production from diverse sources beyond corn.
Technical and Environmental Aspects of Ethanol: This section delves into the technical and environmental aspects of ethanol. While ethanol is a renewable and biodegradable fuel with a long history of use, concerns exist about maximizing corn yields without excessive fertilizer and pesticide use. The chapter highlights the Department of Energy's investment in cellulosic ethanol plants as a key step toward more sustainable and efficient production using sources beyond corn and soybeans. The section concludes with a positive outlook on the future of ethanol technology, emphasizing ongoing research and development efforts towards more environmentally friendly and technically efficient production methods.
