How does a wind turbine turn mechanical power into electricity?

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. 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.

How does a wind turbine work?

Wind turbine is used to extract useful energy from wind. The energy can be extracted by partially decelerating and expanding the airstream (reduction of pressure) using wind turbine. The rotor of the wind turbine collected wind from the whole area swept by the rotor.

How a wind turbine is used for electricity generation?

The kinetic energy of the wind is utilized directly or converted to mechanical energy or used for electricity generation. Apart from its use for grinding grains and pumping water by wind mills, wind turbines are familiar for electricity generation.

How many kilowatts does a wind turbine produce?

Large wind turbines, most often used by utilities to provide power to a grid, range from 100 kilowatts to several megawatts. These utility-scale turbines are often grouped together in wind farms to produce large amounts of electricity.

What is wind power?

The wind power is one of the indirect solar energy technologies. The wind is the air in motion resulting from the pressure gradient caused by solar radiation. About two per cent of the solar radiation reaching the earth’s surface is converted to kinetic energy and this is sufficient to meet the energy demands if it is harnessed.

How do wind farms work?

Wind farms can consist of a few or hundreds of turbines, providing enough power for tens of thousands of homes. Small wind turbines, up to 100 kilowatts, are typically close to where the generated electricity will be used, for example, near homes, telecommunications dishes or water pumping stations.
