CONCEPT: 

  • Solar energy is a renewable source of energy and finds application in ceratin processes like
    • Production of electricity
    • cooking 
  • There are many advantages while using solar energy such as 
    • clean source 
    • Renewable source
    • Reliable 
    • Economic benefits 

EXPLANATION:

  • Solar energy doesn't contain electrical energy and chemical energy. Hence option 1 and 2 is wrong.
  • The solar cooker uses solar energy to cook.
  • In the solar cooker is solar energy is converted into heat energy and the heat energy is used to cook the food. Hence, option 3 is the answer.
  • In solar cookers, heat energy is not converted to chemical energy. Hence option 4 is wrong.
