Most manufacturers rate their turbines by the amount of power they can safely produce at a particular wind speed, usually chosen between 24 mph or m/s and 36 mph or 16 m/s. The following formula illustrates factors that are important to the performance of a wind turbine. Notice that the wind speed, V,.

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.

A wind turbine works by catching the energy in the wind, using it to turn the blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. While some turbines are direct drive, most have a gear box that increases and controls generator speed. Most turbines produce direct current (DC) which ...

Each windmill costs about 300000 and can produce 402 hp (300 kW) of energy. Each of the newer windmills requires about 13 mph (21 kph) speeds to act as a power generator. Interestingly, windmills are designed so that if the wind speed is more than 55 mph ( kph), the turbines shut off automatically.

The amount of energy produced by turbines also depends on the wind speed. Therefore, wind energy is not wellsuited to be a base load energy source AKA our main source of power generation. However, as energy storage technology continues to become more costeffective, it could be possible to become more reliant on wind energy.
