Fully revised, Wind Energy Explained, 2^nd edition, builds on the highly successful 1^st edition – now the leading textbook for wind energy degree courses. With two completely new chapters covering the fundamentals of Data Collection and Analysis and Computer codes and Wind Turbine Design and Testing, Manwell et al draw on substantial practical experience to provide a highly accessible introduction to the cross-disciplinary field of wind engineering. After an introductory chapter covering the wind turbine’s history and modern structures, there are clear chapter headings giving a comprehensive overview of wind characteristics, aerodynamics, mechanics and electronics, sitting, and economical and environmental assessments. New sections have been added on the aerodynamics of vertical axis wind turbines, turbine testing, electrical grid-related issues and current and future applications of wind turbines.
