A wind turbine is a device that converts kinetic energy from the wind, also called wind energy, into mechanical energy; a process known as wind power. If the mechanical energy is used to produce electricity, the device may be called wind turbine or wind power plant. If the mechanical energy is used to drive machinery, such as for grinding grain or pumping water, the device is called a windmill or wind pump. Similarly, it may be called wind charger when it is used to charge batteries.
The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging or auxiliary power on boats; while large grid-connected arrays of turbines are becoming an increasingly important source of wind power-produced commercial electricity.

Famous quotes containing the word wind:
“They went to him and woke him up, shouting, “Master, Master, we are perishing!” And he woke up and rebuked the wind and the raging waves; they ceased, and there was a calm. He said to them, “Where is your faith?” They were afraid and amazed, and said to one another, “Who then is this, that he commands even the winds and the water, and they obey him?””
—Bible: New Testament, Luke 8:24-25.
