The transfer function of the wind turbine is defined as H(f)=P ELEC (f)/P MECH (f) and shown in Fig. 2 for the given wind turbine. Since the system damping, σ, coming from the induction generator windings and the entire grid is not zero, the windmill resonance frequency, f D, is the damped natural frequency expressed by (4) f D =f T 1−σ …

Wind energy and the environment
Wind is an emissions-free source of energy. Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.

The Windmill by Henry Wadsworth Longfellow
Louder and louder roars. The lightness of The Windmill is a concept that is deeply ingrained within the poem itself, and so even the battle-cry-like topic of its third verse cannot deter its inherent cheerfulness. In this verse, the windmill hears the sound of flails, which is a bit of a tough metaphor to decipher initially.

Wind Turbine Blade Aerodynamics | Electrical Academia
A typical drag coefficient for wind turbine blades is 0.04; compare this to a well-designed automobile with a drag coefficient of 0.30. Even though the drag coefficient for a blade is fairly constant, as the wind speed increases, the amount of drag force also increases. The lower the drag coefficient number, the better the aerodynamic efficiency.

How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
