Abstract
This chapter reviews the potential of wind as a sustainable power source. In particular, large-scale offshore wind farms have emerged as critical renewable energy technology to reduce GHG emission and autonomy in energy production. Each of these wind farms consists of many wind turbine generators, each mounted on a support structure and is capable of generating up to 1.2 GW of power. The aim of this chapter is to provide an overview of wind energy and to appreciate the multidisciplinary nature of the engineering issues involved. Recent advances are discussed and the challenges in design and construction are also highlighted.
