1. Energy Efficiency of Lighting http://www.newvictheatre.org.uk/educate/images/lightbulb.jpg Amy Hinkel & Byanca Moreno

2. Lighting Lighting is a form of energy About 25% of home’s electrical use Lighting can affect the way you feel, work, and interact with others. Increasing light efficiency can lower energy bills Needed in the dark Thomas Edison invented the incandescent light bulb

3. http://home.howstuffworks.com/light-bulb.htm

4. Goals Ability to see in the dark Save energy Reducing the pressure to build new power plants and generating less waste for landfills Cutting down the greenhouse gas emissions that contribute to global warming

5. Fact “If every American home replaced just one light bulb with a ENERGY STAR – qualified bulb, we would save enough energy to light more than 3 million homes a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars”

6. Obstacles They burn out Incandescent light bulbs produce greenhouse gases Some are expensive People not realizing the benefits of switching

7. Political/Economic issues Expensive Uses a lot of energy Contains mercury

8. Incandescent Lighting most common in homes Thomas Edison invention traditionally delivered about 85% of household illumination http://static.howstuffworks.com/gif/light-bulb-label.jpg

9. Incandescent Lighting Cont. Inexpensive and easy to find The light is warm emitting most of the light from the yellow to the red end of the spectrum Available in many varieties

10. Compact Fluorescent Combines energy efficiency of fluorescent lighting w/ incandescent fixtures Consist of 2 parts: a gas- filled tube, magnetic/ electronic ballast http://search.msn.com/images/results.aspx?q=compact+lighting&go=Search+Image s&form=QB#focal=f87bd34191a482b168b6a8b6f1a6d34c&furl=http%3A%2F%2Fw ww.preciosa.com%2FNR%2Frdonlyres%2F80F3034E-6FE7-456E-B0B3- 9156D3FFB056%2F0%2Fcompact_lamp.jpg

11. Compact Fluorescent Light (CFLS) use up to 75% less energy than incandescent lights Last ten times longer than a regular incandescent light bulb. More expensive than incandescent lights http://keetsa.com/blog/wp-content/uploads/2007/09/cfl.jpg

12. Electricity Visible light Last longer Entertaining Easily dimmed Silent operation Available in many colors Low-voltage power supply Lack of availability for white LEDs http://www.vorne.com/ http://en.wikipedia.org/wiki/Image:Seven_segment_display-animated.gif

14. Quality of Lighting Light Emitted Light Longevity Light Prices Light Wattage Light Brightness

15. Flood Lighting Provide large amounts of light with minimal energy usage Convenient and efficient http://news.thomasnet.com/images/large/532/532176.jpg http://www.cooperlighting.com/specfiles/pdf/Streetworks/GPF.pdf

16. Natural Lighting paint light colored walls to maximize use of natural light to cut the electricity use All lives because of natural lighting

17. Sky Lights Enhances natural lighting Cuts down on electricity usage Very nice looking and brightens the room up http://www.fakro.ca/img/certy_usa/FX_zespolenie400x408.jpg

18. Light Tubes Used to distribute lighting throughout buildings aka Solar pipes, daylight pipes, or solar light pipes http://www.ambience- lighting.com.au/borderlight/bordertubesclear.jpg

19. Fiber Optics Used in communication, permits transmission over longer distances, at higher data rates than other forms Used instead of metal Used as sensors www.sercos.com/technology/fiber_optics.htm

20. Indoor/Outdoor Lighting www.directoutdoorliving.com/lighting.aspx 64.9.80.131/consumer/onlinecatalo gs.html Indoor Lighting Used in bathrooms, halls, bedrooms, and other often used rooms Use light colored walls to maximize natural lighting Outdoor Lighting Aesthetics- illuminate exterior Security- illuminate house grounds Utility- illuminate porch/ driveway area for navigation

21. Outdoor Solar Lighting Provides free electricity Uses solar cells to convert sunlight to electricity which is stored during the night Must receive sunlight to work www.overstock.com/Home-Garden/Lilies-Three-pi...
