This document discusses limitations of current wind turbine generator (WTG) technology and potential solutions. It provides an overview of WTG design considerations such as the number and shape of blades. It also discusses studies on improving efficiency, including Betz's law stating no turbine can capture over 59.3% of wind's kinetic energy. Recent trends aimed at increasing efficiency and reducing noise and dangers are described, such as gearless and permanent magnet synchronous generator WTGs. The document concludes that while India has significant wind power potential, only 37% is currently harvested, and new WTG designs are needed to overcome limitations around efficiency, noise and wildlife safety.
