Wind energy is a conventional energy source of power generation and a significant player in the today’s energy market. As an unlimited and free energy source, wind is available in majority areas of the world. Wind energy driven turbines uses a variety of composite materials. The details of wind turbine technology along with structure are discussed in this chapter. The historical development of wind turbine technology along with overall structure is briefed. This chapter focuses on the conventional composite materials for wind turbine blades (glass fibers/epoxy matrix composites), natural composites, hybrid and nano-engineered composites technology. A thorough insight in these topics results in appropriate selection of composite materials for wind turbine blade.
