This expanded new edition of Wind Turbines introduces key topics in offshore wind, alongside carefully revised and updated coverage of core topics in wind turbine technology. It features two new chapters on offshore wind, covering offshore resources, metocean data, wind turbine technologies, environmental impact, and loading and dynamics for fixed-bottom and floating platforms. Real-world case studies are introduced from Europe and the USA, and a new chapter examines wind power in the context of broader decarbonisation, practical energy storage, and other renewable energy sources. Updated coverage of turbine energy yield calculations, blade-element momentum theory, and current economic trends is presented, and over 100 varied end-of-chapter problems are included, with solutions available for instructors. Combining key topics in aerodynamics, electrical and control theory, structures, planning, economics, and policy, the clear language of this multidisciplinary textbook makes it ideal for undergraduate and graduate students, and professional engineers, in the renewable energy sector.
