What is wind energy
Wind energy, form of solar energy that is produced by the movement of air relative to Earth’s surface. This form of energy is generated by the uneven heating of Earth’s surface by the Sun and is modified by Earth’s rotation and surface topography. For an overview of the forces that govern the movement of air, see wind. For a description of the harnessing of the wind’s kinetic energy, see wind power.
How Does Wind Create Power?
Wind power or wind energy is a form of renewable energy that harnesses the power of the wind to generate electricity. It involves using wind turbines to convert the turning motion of blades, pushed by moving air (kinetic energy) into electrical energy (electricity). This requires certain technologies, such as a generator that sits at the top of a tower, behind the blades, in the head (nacelle) of a wind turbine.
This aerial view shows how a group of wind turbines, which can be part of a wind power plant or wind farm, make electricity. The electricity created can either provide power to specific needs (like a wind turbine powering a streetlight or isolated farm) or contribute to the electric grid, which then powers homes, businesses, and schools with the help of transmission and distribution cables (or power lines).
A wind turbine turns wind emergy
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. The force of the lift is stronger than the drag and this causes the rotor to spin. The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity.
