  4. Prioritizing

  5. Let’s concentrate on the “important few” for average consumers

  6. How We Use Energy in Our Homes Source: Energy Star.gov Data: Typical House memo, Lawrence Berkeley National Laboratory, 2009 and Typical house_2009_Reference.xls spreadsheet.

  7. BIG IMPACT stuff to do in a minute (or a few minutes) to control lighting • Use more efficient bulbs Photo: National Archives

  8. Making a sustainable choice:Incandescents • Only about 8% of the energy they use creates visible light. • The rest of the energy is wasted as heat!

  9. Making a sustainable choice:Compact fluorescents (CFLs) • About 21% of the energy they use creates visible light. • Most of our energy comes from coal-fired power plants that put mercury into the environment. • Even though CFLs contain a tiny bit of mercury, they reduce the overall amount of mercury that goes into the environment by using less energy.

  10. Making a sustainable choice: Light emitting diodes (LEDs) • About 20-30% of the energy they use creates visible light. • LED technology is changing rapidly. • Check the stores often for new products as they hit the shelves!

  11. When shopping for bulbs …

  12. When shopping for bulbs… what the package can tell you • How much power does the bulb use? Power usage is measured in watts. The greater the wattage, the more power used. • How bright is the light? Brightness is measured in lumens. The larger the number, the more lumens, the brighter the light. Think in lumens… This tells you how much light you are actually getting • How long does the bulb last? Average lifespan is measured in hours. All of these things can tell you how much the lighting really costs!

  13. MORE IMPACT stuff to do in a minute (or a few minutes) to control lighting • Keep the fixtures and the light bulbs clean… Dirty bulbs reduce illumination! • Use daylighting

  14. Let’s take a moment… Please name one thing that you would be willing to do to save lighting energy! Please fill in evaluation

  15. Thank you!
