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.

Wind Energy National Geographic Society

May 31, 2019  Anything that moves has kinetic energy, and scientists and engineers are using the wind’s kinetic energy to generate electricity. Wind energy, or wind power, is created using a wind turbine, a device that channels the power of the wind to generate electricity.. The wind blows the blades of the turbine, which are attached to a rotor. The rotor then spins a generator to create electricity.

WINDExchange: Small Wind Guidebook - Energy

The rotor-swept area (A) is important because the rotor captures the wind energy. So the larger the rotor, the more energy it can capture. The air density, ρ, changes slightly with air temperature and with elevation. The ratings for wind turbines are based on standard conditions of 59° F (15° C) at sea level.

Recent Advances in Rotor Design of Vertical Axis Wind ...

Although wind turbines have been used to generate electricity for some time, it wasn't until the mid 1970s that production of reliable, sizable wind turbines could be produced for the masses [2].Since then, wind turbines gradually increased in size until today, with larger designs topping 6MW capacity with rotor diameters of over 125 m [3].
