Examines the possible societal impacts of wind energy projects and explains the potential issues faced when siting, constructing, and operating a wind energy project.

This book begins with a history of wind power and the social impacts of both electricity and wind power from a historical perspective, a discussion of basic electrical terms, and a primer on the conversion of power in the wind to electricity. Much of the second half of the book is devoted to comparing wind energy to other forms of electric generation, both renewable and non-renewable sources. In order to have a true understanding of the impact of wind energy on society, one also has to have a thorough understanding of the impacts that other sources of electric generation have, such as fossil-fuelled plants or nuclear power plants. The comparison of electric generation sources includes a review of how such sources are typically utilized within the electric system, as well as the economic factors and environmental considerations that affect which resources utilities or operators of electric grids have to take into account. The authors conclude with a discussion of energy policies in the U.S., individual states, and foreign nations, how these policies influence the use of renewable energy, and what our future may hold in terms of energy supply and demand. Some highlights of this book are:

Discusses the wind energy impacts on the environment, local economy, electric utilities, individuals and communities
Provides a visual explanation of wind energy principles through tables, graphs, maps, illustrations and photographs
Offers a comprehensive overview of the issues associated with the creation and use of wind energy
Models chapters around an existing university curriculum

Spanning the broad range of environmental, financial, policy and other topics that define and determine the relationships between wind energy technology and our energy-dependent society, Wind Energy Essentials is a resource for students, universities, and the entire wind energy industry.

Richard Walker has many years of experience in both the electric power and the wind energy industries, in addition to teaching wind energy at Texas Tech University. During his career, he has been involved in electric transmission engineering, solar energy, research and development, state and federal governmental affairs, and the development of over 1,600 MW of wind farms currently in operation (including the first utility-scale wind farm in Texas and the 782 MW Roscoe wind farm, which for several years was the world's largest wind energy project).

Andrew Swift is presently Professor of Civil and Environmental Engineering and the Associate Director of the National Wind Institute at Texas Tech University, where his focus is on wind energy education and workforce development. His previous academic appointments include Director of the Wind Science and Engineering Research Center at Texas Tech and Dean of the College of Engineering at the University of Texas at El Paso.
