Did you know that the typical U.S. family spends about
$1,900 a year on home utility bills?
Unfortunately, a large portion of that energy is wasted…

BIG IMPACT stuff to do in a minute (or a few minutes) to control lighting
Use more efficient bulbs

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!
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.
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!
When shopping for bulbs …
Consider three things: (1) Initial cost; (2) Lifespan; (3) Energy use
To make certain that you are choosing a quality product…• Choose bulbs with the ENERGY STAR logo• Choose bulbs from a reputable manufacturer
Light Source Comparison
Incandescents CFLs LEDs
Initial cost low medium high
Lifespan About 1,000 hours About 10,000 hours About 20,000 hours!
Energy use high low Very low
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!
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
Let’s take a moment…
Please name one thing that you would be willing to do to save lighting energy!
