In the most mature wind markets, the first of these turbines are reaching the end of their operational life

At the same time, the blades have to be extremely resistant to resist to their own weight and to the wind applying forces perpendicular to the main axis. Polyester is cheap and lightweight. Material strength is then infused in it using fiberglass.
