Wind turbine blades are long, aerodynamic structures designed to capture wind energy and convert it into electricity. Typically made from lightweight materials like fiberglass or carbon fiber, these blades can be over 200 feet long. Their shape allows them to efficiently harness wind, spinning around a central hub connected to a generator. The performance of wind turbine blades is crucial for the overall efficiency of a wind turbine. As the blades rotate, they create lift, similar to an airplane wing, which drives the turbine's generator. Proper design and maintenance of these blades are essential for maximizing energy production and ensuring the longevity of the turbine.
