Energy Project

  1. 1. Energy Conservation Project By Adam Zopel By switching to energy-efficient lighting, we can improve the environment, and save some money too.
  2. 2. Questions  Can changing my incandescent lighting to compact fluorescent light (CFL) minimize my carbon footprint?  What is the difference between CFL and incandescent lighting?  How much money can I save by switching to CFL?  Are there any negatives associated with CFL?
  3. 3. What is incandescent lighting?  A lamp that creates radiant energy when its metallic filament is heated by an electric current. -In 1802, English chemist Sir Humphry Davy showed that electric currents could heat thin strips of metal to white heat, thus producing light. This was the beginning of incandescent (defined as glowing with intense heat) electric light.
  4. 4. What is Compact Fluorescent Lighting? (CFL)  CFL is simply a miniature version of full- sized fluorescents. They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs - not like the fluorescent lighting we associate with factories and schools.
  5. 5. Carbon Footprint Using CFL Reduces Air and Water Pollution  Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb.  If everyone in the U.S. used energy-efficient lighting, we could retire 90 average size power plants. Saving electricity reduces CO2 emissions, sulfur oxide and high-level nuclear waste.
  6. 6.  Electric lighting burns up to 25% of the average home energy budget.  The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. How much could we save by using CFL?
  7. 7. Benefits  CFL uses 50 - 80% less energy than incandescent bulbs.  CFL are four times more efficient and last up to 10 times longer than incandescent. A 22 watt CFL bulb has about the same light output as a 100 watt incandescent.
  8. 8. Technological Improvements  Newer CFL give a warm, inviting light instead of the "cool white" light of older fluorescents. New electronically ballasted CFL don't flicker or hum.  CFL can be installed nearly anywhere that incandescent lights are used.
  9. 9. CFL Negatives  Most CFL is produced in China using extensive, "environment polluting" processes. The burning of coal is often involved.  CFL contains the toxic element mercury. Disposal practices have not been verified, nor have the dangers of any leaking mercury been satisfyingly explored and documented.  Electronic equipment and timers may malfunction if they are too close to a CFL.  Prices vary considerably. They are still at the expense end of the lighting market.
  10. 10. Methodology  I will switch to using compact fluorescent light bulbs in three areas of my house.  I will project how much money I’ll save in a one year period.  I will project how much money could be saved if my efforts could be duplicated on a large scale.
  11. 11. INDOOR READING: Incandescent CFL CFL Annual Saving Wattage 100 23 Hrs On/Day 4 4 Annual Cost $11.64 $2.64 $8.82 PORCH LIGHTS: Wattage 75 18 Hrs On/Day 12 12 Annual Cost $25.79 $6.19 $19.60 GARAGE/SHOP Wattage 75 18 Hrs On/Day 8 8 Annual Cost $17.19 $4.13 $13.07 Total yearly savings: $41.49 Here is an analysis of my personal use
  12. 12. Here is an analysis of savings on a massive scale $2,554,500$2,013,960$1,473,420$932,880$392,340 Savings by using CFLs Combined Savings After Five Years Combined Savings After Four Years Combined Savings After Third Years Combined Savings After Two Years Combined Savings After First Year $3.294,000$2,635,200$1,976,400$1,317,600$658,800 90,000 Incandescents (replaced each year) $739,500$621,240$502,980$384,720$266,46090,000 CFLs Total Cost After Five Years Total Cost After Four Years Total Cost After Three Years Total Cost After Two Years Total Cost After One Year
  13. 13. Conclusion  This is really a no-brainer. Switching over to CFL can save you money and they last longer too. The big concern I have is disposal. I’m a little disconcerted with the prospect of all that mercury escaping into our environment.  A future project for someone could be to devise a recycling program for spent CFL.
