: Predominantly steel (66–79% of total mass), with concrete-steel hybrids becoming popular for taller towers to reduce costs.

: Primarily fiberglass-reinforced polymer (GFRP) . Carbon fiber is often integrated into high-stress areas like the "spar cap" (the blade's spine) to add stiffness without excessive weight. Designing Wind Turbines: Engineering and Manufa...

The design process begins by defining parameters like rotor diameter and hub height to determine rated power. Engineers utilize specialized software to optimize performance while adhering to international standards (e.g., IEC classes) that account for site-specific wind speeds and turbulence.

Modern turbines are composed of diverse materials engineered for high-cycle fatigue resistance and weight reduction.

: Shaping airfoils to maximize lift and minimize drag. Airfoils transition from thicker, load-bearing shapes at the root to thinner, aerodynamic profiles at the tip.
