Book Description
The Office of Fuels Development (OFD), a component of the U.S. Department of Energy's (DOE) Office of Transportation Technologies, manages the federal government's effort to make biomass-based ethanol (bioethanol) and biodiesel a practical and affordable alternative to gasoline. Through the National Biomass Ethanol Program, the OFD is overseeing key research and development (R&D) and industry-government partnerships for the establishment of a cellulosic biomass ethanol industry. Cellulosic biomass resources being investigated include agronomic and forest crop residues, woody crops, perennial grasses, and municipal wastes. Starch-based sources, such as cereal grains (e.g., corn grain), are not included in this program. The objective of the program is to promote the commercialization of enzyme-based technologies to produce cost-competitive bioethanol for use as transportation fuel. The OFD requested that the National Research Council estimate the contribution and evaluate the role of biofuels (biomass-derived ethanol and biodiesel) as transportation fuels in the domestic and international economies, evaluate OFD's biofuels strategy, and recommend changes in this strategy and the R&D goals and portfolio of the OFD in the near-term to midterm time frame (about 20 years). During this period, a number of complex, interacting factors, including advances in the technologies used to produce biofuels at a competitive cost, the elimination of tax incentives, advances in vehicle and engine technologies, growing concerns about solid waste disposal and air pollution, and global measures to reduce emissions of greenhouse gases to the atmosphere, will affect the position of biofuels in transportation fuel markets.

Book Description
Biofuels are considered to be the main potential replacement for fossil fuels in the near future. In this book international experts present recent advances in biofuel research and related technologies. Topics include biomethane and biobutanol production, microbial fuel cells, feedstock production, biomass pre-treatment, enzyme hydrolysis, genetic manipulation of microbial cells and their application in the biofuels industry, bioreactor systems, and economical processing technologies for biofuel residues. The chapters provide concise information to help understand the technology-related implications of biofuels development. Moreover, recent updates on biofuel feedstocks, biofuel types, associated co- and byproducts and their applications are highlighted. The book addresses the needs of postgraduate researchers and scientists across diverse disciplines and industrial sectors in which biofuel technologies and related research and experimentation are pursued.

Book Description
Despite the many benefits of energy, most of which are reflected in energy market prices, the production, distribution, and use of energy causes negative effects. Many of these negative effects are not reflected in energy market prices. When market failures like this occur, there may be a case for government interventions in the form of regulations, taxes, fees, tradable permits, or other instruments that will motivate recognition of these external or hidden costs. The Hidden Costs of Energy defines and evaluates key external costs and benefits that are associated with the production, distribution, and use of energy, but are not reflected in market prices. The damage estimates presented are substantial and reflect damages from air pollution associated with electricity generation, motor vehicle transportation, and heat generation. The book also considers other effects not quantified in dollar amounts, such as damages from climate change, effects of some air pollutants such as mercury, and risks to national security. While not a comprehensive guide to policy, this analysis indicates that major initiatives to further reduce other emissions, improve energy efficiency, or shift to a cleaner electricity generating mix could substantially reduce the damages of external effects. A first step in minimizing the adverse consequences of new energy technologies is to better understand these external effects and damages. The Hidden Costs of Energy will therefore be a vital informational tool for government policy makers, scientists, and economists in even the earliest stages of research and development on energy technologies.

Book Description
In legislation appropriating funds for DOE's fiscal year (FY) 2000 energy R&D budget, the House Interior Appropriations Subcommittee directed an evaluation of the benefits that have accrued to the nation from the R&D conducted since 1978 in DOE's energy efficiency and fossil energy programs. In response to the congressional charge, the National Research Council formed the Committee on Benefits of DOE R&D on Energy Efficiency and Fossil Energy. From its inception, DOE's energy R&D program has been the subject of many outside evaluations. The present evaluation asks whether the benefits of the program have justified the considerable expenditure of public funds since DOE's formation in 1977, and, unlike earlier evaluations, it takes a comprehensive look at the actual outcomes of DOE's research over two decades.

Book Description
This book focuses on the different kinds of biofuels and biofuel resources. Biofuels represent a major type of renewable energy. As part of a larger bio-economy, they are closely linked to agriculture, forestry and manufacturing. Biofuels have the potential to improve regional energy access, reduce dependence on fossil fuels and contribute to climate protection. Further, this alternative form of energy could revitalize the forestry and agricultural sector and promote the increased use of renewable resources as raw materials in a range of industrial processes. Efforts are continuously being made to develop economically competitive biofuels, and microbes play important roles in the production of biofuels from various bioresources. This book elaborates on recent advances in existing microbial technologies and on sustainable approaches to improving biofuel production processes. Additionally, it examines trends in, and the limitations of, existing processes and technologies. The book offers a comprehensive overview of microbial bioresources, microbial technologies, advances in bioconversion and biorefineries, as well as microbial and metabolic engineering for efficient biofuel production. Readers will also learn about the environmental impacts and the influence of climate change on the sustainability of biofuel production. This book is intended for researchers and students whose work involves biorefinery technologies, microbiology, biotechnology, agriculture, environmental biology and related fields.

Book Description
This report is a congressionally mandated review of the US Department of Agriculture's Research, Education, and Economics (REE) mission area, the main engine of publicly funded agricultural research in the United States. A changing social and scientific context of agriculture requires a new vision of agricultural research-one that will support agriculture as a positive economic, social, and environmental force. REE is uniquely positioned to advance new research frontiers in environment, public health, and rural communities. The report recommends that REE be more anticipatory and strategic in its use of limited resources and guide and champion new directions in research.

Book Description
Since CAFE standards were established 25 years ago, there have been significant changes in motor vehicle technology, globalization of the industry, the mix and characteristics of vehicle sales, production capacity, and other factors. This volume evaluates the implications of these changes as well as changes anticipated in the next few years, on the need for CAFE, as well as the stringency and/or structure of the CAFE program in future years.
