A turbine is a machine that spins around in a moving fluid (liquid or gas) and catches some of the energy passing by. A wind turbine is a device that converts kinetic energy from the wind into electrical energy. In the same way that a windmill can harness the power of the wind to grind wheat or pump water, a modern wind turbine uses the wind to provide the energy we need rot run our homes and our businesses.
This description is intended to describe to a non-technical audience the basic process of how wind turbines convert wind into electricity.
To operate, a wind turbine needs rotors (blades), a gearbox, a generator and a tower. It also needs adequate wind. Wind Power Density (WPD) is derived from a combination of wind speed, wind sustainability, turbulence, height above the ground and a number of other factors. Depending on their size, turbines need wind speeds of between 12 and 45 miles per hour in order to generate electricity.
The top part of the turbine rotates so that the blades are facing the wind. a combination of a gearbox and a generator then turn the power of the wind into electricity which is stored in a nearby substation to be used when it is needed.
Special Terms
Nacelle: main body of the turbine which contains a gearbox and a generator Anemometer: instrument that measures wind speed
The major steps explained here are: 1. Capturing the wind 2. Converting the power 3. Providing electricity

Converting
Converting is the stage at which the kinetic wind energy is changed into electric energy that can be used by people. As the rotors spin around slowly (capturing the kinetic power of the wind), they turn the central drive shaft. Inside the nacelle, the gearbox then converts the low-speed rotation of the central shaft (approx. 16 rpm) into a high-speed rotation (1600 rpm) fast enough to drive the generator efficiently. Next, the generator, which is located behind the gearbox, takes the kinetic energy from the spinning drive shaft and converts it into electrical energy.
e.g.

e.gConclusion Wind turbines convert the kinetic power of the wind into electrical power that can be used by people in three major stages; 1) capturing the wind, 2) converting kinetic energy into electrical energy and 3) providing energy to homes and buildings.
Instruments attached to the turbine measure the speed and direction of the wind so that the rotors can turn to face directly into it. The wind causes the rotors to spin which turns the central shaft they are mounted on. A gear box increases the speed of the revolution until it is fast enough to power a generator. The generated electrical energy is then transported down the tower and through a transformer to an electrical substation which provides the energy to nearby communities.
