HOW WIND TURBINES WORK:.

Wind:.
Wind is a form of solar energy.

Cause of Wind:.
Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth.

WIND TURBINE:.

Principle of Wind Energy:.
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy of the wind into mechanical power.

Use:.
This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

                               How Do Wind Turbines Make Electricity?

Principle:.
Wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity.

Working:.
The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

                                 Inside View Of  Wind Turbine:.

1: Anemometer:
Measures the wind speed and transmits wind speed data to the controller.

2: Blades:
Most turbines have either two or three blades. Wind blowing over the blades causes the blades to "lift" and rotate.

3: Brake:
A disc brake, which can be applied mechanically, electrically, or hydraulically to stop the rotor in emergencies.

4: High-speed shaft:.
Drives the generator.

5: Low-speed shaft:.
The rotor turns the low-speed shaft at about 30 to 60 rotations per minute.

6: Rotor:
The blades and the hub together are called the rotor.
