A highly accessible and authoritative account of wind energy's scientific background, current technology, and international status, with an emphasis on large turbines and wind farms, both onshore and offshore Topics covered include: a brief history of wind energy the nature of the wind turbine aerodynamics, mechanics, and electrics wind farms offshore opportunities and challenges grid integration of wind energy economic and environmental aspects Whilst intellectually rigorous, this is not an academic treatise. Key equations are fully discussed, providing essential theoretical background. The text is supported by copious illustrations and about 50 inspiring full-colour photographs from around the world. This book is aimed at a wide readership including professionals, policy makers and employees in the energy sector in need of a basic appreciation of the underlying principles of wind energy or a quick update. Its style and level will also appeal to second and third year undergraduate and postgraduate students of renewable and wind energy, energy systems and electrical/electronic engineering. It also gives a concise account of the technology for the large and growing number of people who are interested in onshore and offshore wind farms and the contribution they are making to carbon-free electricity generation in the 21st century.

A lively and authoritative account of today's photovoltaic (PV) technology and its practical applications This book covers areas including: * a brief history of PV, and the current international scene; * the scientific principles of solar cells including silicon and new thin-film varieties; * PV modules and arrays; * grid-connected PV, from home systems up to large power plants; * the wide diversity of stand-alone PV systems, and; * the economic and environmental aspects of solar electricity. Key equations and numerical examples are fully discussed, providing essential theoretical background. The text is supported by copious illustrations and more than eighty inspiring full colour photographs from around the world to demonstrate PV's huge range of practical applications. This book is aimed at a wide readership including professionals working in related areas, and students taking introductory courses in PV and renewable energy. Its style and level will also appeal to energy planners and decision makers, members of environmental organisations, and the increasing number of people interested in generating their own electricity from sunlight.

\"A concise yet technically authoritative overview of modern marine energy devices with the goal of sustainable electricity generation With 165 full-colour illustrations and photographs of devices at an advanced stage, the book provides inspiring case studies of today's most promising marine energy devices and developments, including full-scale grid-connected prototypes tested in sea conditions. It also covers the European Marine Energy Centre (EMEC) in Orkney, Scotland, where many of the devices are assessed.Topics discussed: global resources - drawing energy from the World's waves and tides history of wave and tidal stream systems theoretical background to modern developments conversion of marine energy into grid electricity modern wave energy converters and tidal stream energy converters This book is aimed at a wide readership including professionals, policy makers and employees in the energy sector needing an introduction to marine energy. Its descriptive style and technical level will also appeal to students of renewable energy, and the growing number of people who wish to understand how marine devices can contribute to carbon-free electricity generation in the 21st century\"--

Finding ways to safely store and ultimately dispose of nuclear waste remains a matter of considerable debate. This volume describes the steps needed to design a new, single-purpose organization to manage and dispose of commercial and defense high-level radioactive materials and examines three models for such an organization—federal government corporation, federally chartered private corporation, and independent government agency.

A comprehensive exploration of 21st Century school politics,Teachers versus the Publicoffers the first comparison of the education policy views of both teachers and the public as a whole, and reveals a deep, broad divide between the opinions held by citizens and those who teach in the public schools. Among the findings: * Divisions between teachers and the public are wider and deeper than differences between other groups often thought to contest school policy, such as Republicans and Democrats, the young and the old, the rich and the poor, or African Americans and whites. * The teacher-public gap is widest on such issues as merit pay, teacher tenure reform, impact of teacher unions, school vouchers, charter schools, and requirements to test students annually. * Public support for school vouchers for all students, charter schools, and parent trigger laws increases sharply when people are informed of the national ranking of student performance in their local school district. * Public willingness to give local schools high marks, its readiness to support higher spending levels, and its support for teacher unions all decline when the public learns the national ranking of their local schools. * On most issues, teacher opinion does not change in response to new information nearly as much as it does for the public as a whole. In fact, the gap between what teachers and the public think about school reform grows even wider when both teachers and the public are given more information about current school performance, current expenditure levels, and current teacher pay. The book provides the first experimental study of public and teacher opinion. Using a recently developed research strategy, the authors ask differently worded questions about the same topic to randomly chosen segments of representative groups of citizens. This approach allows them to identify the impact on public opinion of new information on issues such as student performance and school expenditures in each respondent's community. The changes in public opinion when citizens receive information about school performance are largest in districts that perform below the national average. Altogether, the results indicate that support for many school reforms would increase if common core state standards were established and implemented in such a way as to inform the public about the quality of their local schools. These and many other findings illuminate the distance between teacher opinions and those of the public at large. About the Research:In partnership with the Harvard Program on Education Policy and Governance and the journal, Education Next, authors Paul E. Peterson, Martin West and Michael Henderson surveyed nationally representative samples of teachers and the public as a whole annually between 2007 and 2013.

This book explains the history and strategy of the intelligent design creationist movement, which is headquartered at the Discovery Institute’s Center for Science and Culture in Seattle, WA. The movement’s twenty-year “Wedge Strategy,” implementation of which began in 1998, is aimed at bringing intelligent design into American public schools, public policymaking, and the cultural mainstream. Beginning with a brief history of the movement and the authentication of the “Wedge Document,” in which the Wedge Strategy is outlined, the book critiques the incompetent science and rhetorical tactics of the movement’s leaders: Douglas Axe, Paul Chien, Jonathan Wells, Michael Behe, and William Dembski. The movement’s own documents reveal its religious funding sources and its execution of all phases of the strategy except the production of genuine scientific data, including its development of a legal defense against challenges to the teaching of intelligent design. The book recounts the movement’s political maneuvering in its effort to influence science curricula in individual states, most notably Kansas and Ohio, and to develop political support among members of Congress. Importantly, the book documents the centrality of religion to intelligent design, its leaders’ associations with Christian extremists, its continuity with earlier forms of creationism, and its ambitions for academic legitimacy. This 2007 edition provides updates on the movement’s efforts in Kansas and Ohio and offers a firsthand account by Barbara Forrest, who was an expert witness for the plaintiffs, of the landmark legal case involving intelligent design, Kitzmiller et al. v. Dover Area School District (2005).
