Wind and Water describes conventional hydropower, or wind power, and some of the newer technologies (with less certain futures) that are being introduced to harness the power of ocean currents, ocean waves, and the temperature difference between the upper and lower layers of the ocean. The strengths and limitations of each technology are discussed as well as mathematical models that describe the maximum amount of energy that can be harnessed by such devices. This comprehensive new volume also examines how these power producers benefit from government support and the economics of operating these types of generating stations. An interview with Dr. Stan Bull, former associate director for science and technology at the National Renewable Energy Laboratory, is included in which he shares his views about how scientific research is and should be managed, nurtured, and evaluated.
This compelling saga recounts the human effort to capture the power of the wind for electricity--from the first European windmills, to nineteenth century experiments in rural electrification, to the immense wind farms in California and the plains states that feed power grid today.Environmental historian Robert W. Righter describes eccentric inventors and techinical innovations, analyzes the politics of the power industry, past and present, and demonstrates that individuals and small businesses have made the greatest contributions to wind-energy development. Wind Energy in America also focuses on contemporary developments, including U.S. government research and regulation and the international race for dominance in the wind-turbine business. Righter explores the arguments of people and organizations opposed to the spread of wind generators--often the same environmental groups, paradoxically, that hailed wind energy as a savior in the late 1970s.This abundantly illustrated history, free of ideology and cant, will be of lasting interest to environmentalists, scholars, and all readers alert to the need for alternatives to coal and oil.

Among renewable sources wind power systems have developed to prominent s- pliers of electrical energy. Since the 1980s they have seen an exponential increase, both in unit power ratings and overall capacity. While most of the systems are found on dry land, preferably in coastal regions, off-shore wind parks are expected to add signi?cantly to wind energy conversion in the future. The theory of modern wind turbines has not been established before the 20th century. Currently wind turbines with three blades and horizontal shaft prevail. The drivenelectricgeneratorsareoftheasynchronousorsynchronoustype,withorwi- out interposed gearbox. Modern systems are designed for variable speed operation which make power electronic devices play an important part in wind energy conv- sion. Manufacturing has reached the state of a high-tech industry. Countries prominent for the amount of installed wind turbine systems feeding into the grid are in Europe Denmark, Germany and Spain. Outside Europe it is the United States of America and India who stand out with large rates of increase. The market and the degree of contribution to the energy consumption in a country has been strongly in?uenced by National support schemes, such as guaranteed feed-in tariffs or tax credits. Due to the personal background of the author, the view is mainly directed on Europe, and many examples are taken from the German scene. However, the sit- tion in other continents, especially North America and Asia is also considered.
