This handbook considers the use and applications of horizontal axis wind turbines, detailing how wind power can be most efficiently harnessed for the production of electricity. The authors provide a broad view of the issues raised by this technology, addressing engineering, environmental, social, and economic interests. Analyses material fatigue and examines component design from blades and generators to gearboxes and brakes Assesses the wind resource in terms of wind characteristics, statistics, turbulence, and speed prediction techniques Considers the aerodynamics, performance, and design of horizontal axis wind turbines Examines the environmental impact of wind farms from noise and appearance to the effects on bird life Links wind turbines to the power system and investigates the need for stability when integrated into electricity grids
