Be An Energy Producer

  1. 1. Be an energy producer through conservation
  2. 2. The Scope <ul><li>Each unit (kWh) of electricity conserved is equivalent to production of 1.25 units considering the transmission and distribution (T & D) losses. </li></ul><ul><li>This would mean that each time you save 1kWh of electricity , you are in effect helping your utility to generate an extra 0.25 kWh. </li></ul>
  3. 3. “ Conservation is the quickest, cheapest and most practical source of energy” Jimmy Carter: Energy Policy Speech, April 1977
  4. 4. Environmental effects <ul><li>Generation of 1 MW of electricity using oil or coal produces about 7,000 MT of CO 2 annually together with the other greenhouse gases like carbon monoxide and Nitrous oxide. </li></ul><ul><li>Each unit of electricity conserved will reduce your carbon footprint by nearly 1kg and help mitigate the global warming. </li></ul>
  5. 5. <ul><li>Win, Win and Win </li></ul><ul><li>By cutting down your consumption </li></ul><ul><li>You reduce your utility bill </li></ul><ul><li>You save the environment </li></ul><ul><li>You help generate power </li></ul>
  6. 6. How can you do it?
  7. 7. Replace that incandescent bulb! <ul><li>An incandescent bulb converts only 2-10% of the electricity it consumes into useful light; other 98-90% is wasted as heat. </li></ul><ul><li>A 100 W incandescent bulb has an average lifetime of only 750 hours. </li></ul>
  8. 8. What are your options ? Cagle Cartoons <ul><li>Compact Fluorescent Lamps (CFL) </li></ul><ul><li>Triphosphor Efficient Fluorescent Tubes ( T8 , T5 ) with electronic ballasts </li></ul><ul><li>White Light emitting Diodes (WLED) </li></ul>This presentation deals only with the CFLs
  9. 9. Luminous Efficacy: Total luminous flux emitted divided by the wattage of the source (power consumed). Units lumens /watt (lm/w) *Prototype
  10. 10. Incandescent bulb vs. CFL Light Output Comparison Source: USDOE 30-52 2,600 150 23-30 1,600 100 18-25 1,100 75 13-15 800 60 9-13 450 40 Watts Lumens Watts Compact Fluorescence Lamp Light output Incandescent bulbs
  11. 11. Life span <ul><li>A CFL bulb typically lasts about 7000-8000 hours compared to 800-1000 hours of the incandescent bulb. </li></ul>
  12. 12. Check the numbers! <ul><li>A 13 W CFL produces the same light output as a 60W incandescent bulb. </li></ul><ul><li>If used 6 hours/ day , you save 282 Wh /day or 0.282 units of electricity/day/bulb </li></ul><ul><li>Replacing 4 bulbs in a house saves 1.128units/day or 412 units/year </li></ul><ul><li>This in effect would mean you helped generate 515 kWh/year (considering 25% T&D loss) </li></ul><ul><li>A thousand households can ‘produce’ 515 MWh /year by simply replacing their bulbs with CFLs. </li></ul><ul><li>This is roughly equivalent to the electricity produced by 25 diesel generators (18 kVA) in rural Fiji. </li></ul>
  13. 13. Check the numbers (contd.) <ul><li>Each 18kVA generator runs for 3.6 hours/day and consumes 8.2 L of diesel per day. </li></ul><ul><li>By switching to CFL (25 x8.2=) 205 L of diesel can be saved. </li></ul><ul><li>This would result in GHG reduction of 500 kg of CO 2 annually. </li></ul><ul><li>And cut the fuel import bill. </li></ul>
  14. 14. Check the numbers (contd.) Cost- benefit analysis -Fiji electricity Authority (FEA) (All costs in Fiji$) 71% 70% 69% 59%         % Savings $76 $57 $45 $27         Savings                   $32 $25 $21 $19 $108 $82 $67 $46 Total Cash Outlay                   $21.62 $15.44 $11.32 $9.27 $102.95 $77.21 $61.77 $41.18 Operation Cost to run 5000 hours $10 $10 $10 $10 $5 $5 $5 $5 Purchase Cost (Capital) 21 15 11 9 100 75 60 40   Watts One Energy Saver Bulb 5 Regular Bulbs  
  15. 15. CFL promotion in Fiji
  16. 16. CFL ads <ul><li>Ratatouille and Department of Energy TV Spot Don't be an a..-Greenpeace ad Havells India ad </li></ul>
  17. 17. Some issues with CFL <ul><li>Environmental: CFLs contain a small amount of mercury (similar to ordinary tubes ~5mg). Broken CFLs should be disposed off properly. </li></ul><ul><li>Flicker: Some CFLS have a pronounced flicker which is uncomfortable to some people. Newer CFLs use high frequency electronic ballasts which reduce the flicker to a large extent. </li></ul>
  18. 18. Be Energy Smart
