Wind energy is produced in varying power due to the movement of air between an unevenly heated atmosphere and the irregular surface of the earth.
The power of wind lets it exert force, create movement, and transfer energy to elements within the environment.
A wind turbine produces electricity by using the kinetic or moving energy of wind to create motion. When there is a satisfactory level of power in the wind it can exert a force, causing a the rotor to spin which when coupled to a generator converts the rotation into electricity.
A wind turbine operates on a simple principle: The wind turns the blades, spins a drive shaft, fed through a gearbox, delivers the motion required for a generation unit to produce electricity by using the motion to create a magnetic field and generate an electrical current.
The electricity produced is collected through underground cables that connect each turbine to a substation, where the power is transferred to the local power distribution network to be used by local homes and businesses, or enters the national power network where it is rerouted to areas of high electricity demand, such as: urban centres.
