resources

7. Now this is an high time to convert into
renewable resources

8. Because, if we continuously use these existing
resources then it will lead to severe shortages
and crisis of electricity and petroleum

10. Types of renewable energy resources:
• Solar energy:

11. It is calculated that sun’s energy wouldlast for more
than 1 billionyears

13. •Wind energy:

16. Hydropower energy:

18. Bio-diesel:

20. Bio-diesel is a clean and efficient fuel and
does not emit any green house gases.

21. We students can conserve energy by adopting simple techniques
Switch OFF electrical appliances which are working wastely

22. Always use front load washing machine because
top load washing machine use high amount of
electricity and water

23. Switch old incandescent bulbs into CFL
and LED bulbs

25. Air conditioners should be operated at a
temperature of 20 degrees in winter and 26
degrees in summer to save energy and to
enjoy optimum cooling performance
