  • Renewable

  • All purpose : heating, cooking, and lighting.


Disadvantages of solar energy
Disadvantages of Solar Energy

  • If there is no sun on a cloudy day, then there is no power.

  • Solar stations are very expensive.


Wind

  • Wind energy is wind. This is also a renewable source of energy.

  • Wind turbines are used to convert this energy into electricity.-



Advantages of wind energy
Advantages of Wind Energy

  • No pollution.

  • Renewable.

  • Stations can be made off shore as well as on land.


Disadvantages of wind energy
Disadvantages of Wind Energy

  • If there is no wind then there is no power
