Wind power can be obtained from wind energy by wind machines. Wind machines capture the wind and convert the energy present in it to mechanical or electrical energy called wind power.
Wind machines use blades to capture kinetic energy of the wind and turn by the force of the wind. The blades are connected to the shafts of turbine which is rotated by the wind power to generate electricity.
On the basis of the direction of the rotating shaft, there are two types of wind machines available today. Horizontal axis wind machines which have blades like that of an airplane propeller. Horizontal axis wind machines are very tall and have three long blades to capture more wind and therefore generate more wind power. Vertical axis wind machines are not much in use. They have blades that go from top to bottom. Vertical axis wind machines account for a very small amount of wind power generated.
Another type of wind machine or system used to generate electricity using wind power is the Wind Amplifier Rotor Platform. This system has modules stacked on one another. Each module has a pair of high capacity turbines and a wind amplifier. The wind amplifier increases the speed of the wind directed towards the turbines. The wind rotates the turbines that generate electricity.
Wind power is used to generate a large amount of electricity that can meet electricity needs of many nations of the world conveniently, efficiently and in a cost effective manner.
