  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. Geothermal Energy • A lot of energy exists inside earth crust. Natural hot water springs are a good source of getting such energy.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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. Energy Conservation in India • In India, government has passed “Energy Conservation Bill, 2001” for better utilization of energy and conservation of the same. • By this act, it is mandatory for energy intensive sectors to get their “Energy Audit” conducted by accredited energy auditor.

  15. Bureau of Energy Efficiency • This body keeps watch on energy consumption patterns, develops norms for appliances etc. • It also organizes different competitions e.g. poster & slogan competition etc. for children. • For details, please visit: www.energymanagertraining.com

  16. Star Ratings • BEE has also initiated “Star Rating System” for electrical appliances e.g. refrigerator, CFL, geysers etc. • In this system, 1-5 stars are allotted to products depending on their energy efficiency. A five star product means that it consumes least energy in its segment.

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

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

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

  20. 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!)

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

  22. 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.

  23. At Home • We should not open fridge door frequently.

  24. At Home • We should not open fridge door for long time.

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

  26. 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.

  27. How will it help? • Take an example: • We replace one 100W bulb with a 13W CFL. • Let us assume electricity is available for Rs. 3.00 per unit, and this bulb is used for 6 Hours a day. • The annual saving would be….

  28. Power Saving • Power saved: 100W-13W = 87W =87W X 6 Hours X 365 Days =17520 WH =17.520 kWH or Units =Rs. 52.56 Say Rupees 50 per one bulb replaced.

  29. 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.

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