Rising energy prices and concern over greenhouse gas emissions have focused congressional attention on energy alternatives, including wind power. Although wind power currently provides only a small fraction of U.S. energy needs, it is growing more rapidly than any other electricity source. Wind energy already plays a significant role in several European nations, and countries like China and India are rapidly expanding their capacity both to manufacture wind turbines and to integrate wind power into their electricity grids. This book describes utility-scale wind power issues in the United States as well as background on wind energy, wind resources and technology, industry composition and trends, wind power economics and policy issues. Other policy questions, such as federal funding for wind research and development, and siting and permitting requirements, are also outlined.
