What is Wind energy?
Wind energy refers to the process by which wind turbines
convert the movement of wind into electricity.
A windmill is defined as a machine that converts the kinetic energy of the wind into mechanical
energy. All the blades of windmill always rotate in a clockwise direction. The first windmill
was designed in the year 1854 by Daniel Halladay from the United States.
The number of blades of the windmill was determined after many trial and error methods. It
was found that three blades worked the best and that’s how every windmill has three blades. The
energy source for windmill is wind. When the blades come in contact with the wind, the blades
move such that the shaft starts to spin, resulting in the production of electricity. The
generator converts the mechanical energy into electrical energy.
