Answer 2

Electric energy can be produced from sources such as wind, water and sun, in the following ways -

• Electricity production from wind :

- We can produce electricity from wind energy by using windmills.

- The fan blades of a windmill rotates by the mechanical energy of the wind flow.

- The rotating fan is connected with the shaft of a dynamo which later produces electricity.

Here,the mechanical energy of the wind flow is converted into electrical energy.

• Electricity production from the water :

- We can produce electricity from water by using water turbine.

- The high velocity water flow rotates the water turbine.

- This water turbine is connected to the shaft of a dynamo which later produces electricity.

Here, mechanical energy of the wind is converted into electrical energy.

• Electricity production from the sun :

- We can produce electricity from the solar radiation by using solar panels.

- The solar radiation excites are semiconductor present in the solar panel.

- This excited semiconductor produces electricity.

Here,the solar energy is converted into electrical energy.
