What is wind energy?

Wind energy is the kinetic energy possessed by air in motion (also called wind). The higher the wind speed, the higher its kinetic energy. Wind energy is the use of wind to provide mechanical energy through wind turbines to turn electric generators for electrical energy.

What is wind power?

Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.

How much energy does a wind turbine produce?

There are over 70,000 utility-scale wind turbines installed in the U.S. Based on a standard capacity factor of 42%, the average turbine generates over 843,000 kWh per month. However, there’s no black-and-white answer to how much energy a wind turbine produces, as energy output varies depending on turbine type and location.

How do you calculate wind energy?

The formula (equation) to calculate wind energy is : where: The unit of measurement of wind energy is joule [J]. The air flow area, also called swept area, is the area through the air (wind) is flowing. The swept area of the turbine can be calculated from the length of the turbine blades using the equation for the area of a circle: where:

How is wind used to produce electricity?

Wind is used to produce electricity by converting the kinetic energy of air in motion into electricity. In modern wind turbines, wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational energy is transferred by a shaft which to the generator, thereby producing electrical energy.
