Question
Explain the stages in electric generation from the given schematic diagram.

Solution
- Electricity generation using wind energy is done with the help of a wind turbine.
- A wind turbine is a machine used to convert the kinetic energy of the wind to electrical energy.
- A wind turbine consists of rotating blades, a gear box and a generator.
- When the wind strikes the blade of the turbine, the blades rotate.
- The axle of the turbine is connected to the electric generator through a gear box.
- The gear box is used to increase the rotations per unit time.
- In this way, the rotating blades run the turbine which in turn drives the generator to produce electricity.
