Enormous in scope, this book presents in comprehensive and logical form the sum of our national knowledge about renewable energy resources. It deals with these resources in terms of opportunities and dangers, in terms of current availability and possible expansion, in terms of how natural resources relate to human resources and needs, and in terms of their replacement potential for nonrenewable resources such as fossil fuels. It also puts domestic resources and needs into the context of international needs, supplies, and policies, emphasizing the issues facing an interdependent world and the urgent requirements perceived by countries less endowed than the United States. This is a handbook for the concerned citizen as well as for resource managers and policymakers at local, regional, and national levels. The analyses it contains underscore the fact that there are no easy answers: everything is part of an interlocking system, and every decision will affect multiple aspects of our daily lives and indeed our very existence. The authors emphasize the crucial importance of early planning, balanced management, and timely decisions, while suggesting that something more is required—a new ideology and a new educational approach.

A component in the America's Energy Future study, Electricity from Renewable Resources examines the technical potential for electric power generation with alternative sources such as wind, solar-photovoltaic, geothermal, solar-thermal, hydroelectric, and other renewable sources. The book focuses on those renewable sources that show the most promise for initial commercial deployment within 10 years and will lead to a substantial impact on the U.S. energy system. A quantitative characterization of technologies, this book lays out expectations of costs, performance, and impacts, as well as barriers and research and development needs. In addition to a principal focus on renewable energy technologies for power generation, the book addresses the challenges of incorporating such technologies into the power grid, as well as potential improvements in the national electricity grid that could enable better and more extensive utilization of wind, solar-thermal, solar photovoltaics, and other renewable technologies.
