There are two main categories of energy: renewable and non-renewable. Renewable energy sources like solar, wind, and hydro can be continuously generated without depletion, while non-renewable sources like fossil fuels are finite. It is important to conserve energy because demand is increasing while fuel sources are limited and will eventually be depleted. Small actions like switching off lights when not in use, using public transport, and purchasing energy efficient appliances can help reduce energy consumption and prolong our remaining fuel reserves.

1. ENERGY CONSERVATION

2. Types of Energy Energy can be broadly divided into two categories- Renewable Energy Non Renewable Energy

3. Renewable Energy Renewable energy can be generated continuously practically without decay of source. E.g.- Solar Energy Wind Energy Geothermal Energy Hydro Energy

4. Solar Energy Solar energy can be converted into electrical energy by using solar panels, or alternatively, be used as thermal energy using solar water heaters, solar cookers etc.

5. Wind Energy India is world’s third largest producer of electricity generation using wind power by wind mills.

6. Hydro Energy Using dams, water is allowed to pass through turbine blades, which produces electricity. In India, after coal, most of the energy is produced by this method.

7. Non Renewable Energy Non renewable energy cannot be generated again and again, e.g. energy generated from combustion of fossil fuels, energy from coal and gas etc.

8. Energy Energy can neither be generated nor it can be destroyed. It can only be converted from one form to another. For example, in a room heater, electrical energy is converted to the thermal energy. Turbine converts mechanical energy stored in steam to electrical energy.

9. Why to Conserve? We have limited fuels available on earth. Our demand for energy is increasing day-by-day. It is possible that someday, most of fuels will be exhausted, and we will have to switch over to alternate energy.

10. Limited Fuels At present consumption levels- Crude oil will last only for 40 years. Gas will last for 60 years. Coal will be finished in nearly 200 years. Ever thought of life without oil and gas?

12. Increasing Consumption Furthermore, our consumption is increasing day-by-day. This means fuels will last much earlier than expected. The only solution is …..

13. Energy Conservation

14. What Can We Do? We, the children can do our bit to save energy. We should not waste energy in school or at home.

15. In School Always switch off lights and fans while going out of the class.

16. In School In computer lab, we should switch off computers before going out of class.

17. In School If there are less students in the class, we should sit together so that some fans can be switched off. (NOT IN EXAMS!)

18. At Home We should not keep light and fan unnecessarily switched on.

19. At Home Tell mother to take material out from fridge if it is to be heated, some time earlier so that cooking gas consumption is low.

20. At Home We should not open fridge door frequently.

21. At Home Watching interesting programs on TV is interesting, but afterwards, TV should be switched off.

22. At Home While going to purchase new products, e.g. refrigerator, geysers, CFL etc., we should insist upon purchasing a five star product rather than cheap and energy waster product.

23. So, Remember to replace light bulbs with CFLs so electricity could be available for more time. You can also ask your parents for a chocolate or some other gift after reducing your electricity bill.

24. What Else can be Done? We should discuss energy conservation with our friends and tell others how can we reduce energy consumption.
