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.
Then, how much power can be captured from the wind? This question has been answered in a paper published in 1919 by a German physicist Albert Betz who proved that the maximum fraction of the upstream kinetic energy K that can be "absorbed" by an ideal "actuator" – not necessarily a turbine, but any device capable of converting wind energy

Wind energy (or wind power) refers to the process of creating electricity using the wind or air flows that occur naturally in the earth''s atmosphere. Modern wind turbines capture kinetic energy from the wind to generate electricity. The first step is wind blowing across the blades of the turbine.
Each of these turbines consists of a set of blades, a box beside them called a nacelle and a shaft. The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy. The blades rotating in this way then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical

Wind turbines are analogous: like cars, they''re designed to work efficiently at a range of different speeds. A typical wind turbine nacelle is 85 meters (280 feet) off the ground—that''s like 50 tall adults standing on one another''s shoulders! There''s a good reason for this. If you''ve ever stood on a hill that''s the tallest point for miles

Wind Resource and Potential Approximately 2% of the solar energy striking the Earth''s surface is converted into kinetic energy in wind. Wind turbines convert the wind''s kinetic energy to electricity without emissions.1 The distribution of wind energy is heterogeneous, both across the surface of the Earth and vertically through the atmosphere.
