This book performs a multidisciplinary approach of wind energy and analyzes existing wind technologies to propose novel modeling techniques and control systems and explore novel applications. The authors discuss whether wind energy is a valid alternative from the point of view of feasibility to be integrated in buildings or desalination plants, among others. The results support that wind energy is a profitable alternative that can also be used in several different applications different from large-scale plants. Finally, in this book, a chapter is included to evaluate the feasibility and economic, social and environmental implications of large-scale wind plants in locations where no previous development exists and where specific complex characteristics must be considered and a case study for the largest wind plant in Ecuador is presented. As a result, readers can access a detailed approach to wind energy from a technical point of view and consider novel applications and related implications of this renewable energy.
