Through an exploration of the evolution from traditional materials to cutting-edge composites, the paper highlights how these developments significantly enhance the efficiency, durability, and environmental compatibility of wind turbines. . Wind turbine blades are the critical interface between the natural energy of the wind and the mechanical power that drives electricity generation. Detailed case studies of notable global projects, such as. . In 2012, two wind turbine blade innovations made wind power a higher performing, more cost-effective, and reliable source of electricity: a blade that can twist while it bends and blade airfoils (the cross-sectional shape of wind turbine blades) with a flat or shortened edge. Wind power is ecologically friendly and provides significant benefits over conventional fossil fuels because it is a clean and renewable form of energy. Wind. . Harnessing energy from low wind velocity requires the design of small-scale wind turbines using airfoils that can operate at a low Reynolds number ( (Re < 500,000)).
