From 10 to 13 percent of the average home's electricity costs can be
controlled with the flip of a switch - a light switch. Increasing your
lighting efficiency is one of the fastest ways to decrease your energy bills.
If you replace 25% of your lights in high-use areas with fluorescents, you can
save about 50% of your lighting energy bill.
Replace all light fixtures and bulbs that operate four or more hours a day
with ones that use fluorescent bulbs to save money and energy. Use lumens --
the amount of light produced -- to compare lights. For example, a 23-watt
fluorescent bulb produces about the same number of lumens as a 100-watt
incandescent. Your investment will generally pay for itself in a couple of
years since fluorescents last 6 to 10 times longer than incandescent bulbs and
are four times more energy efficient.
Lighting Tips
(from the U.S. Department of Energy's Energy
Savers - Tips on Saving Energy and Money at Home)
Indoor
-
Turn off the lights in any room you're not using or consider installing
timers, photo cells or occupancy sensors to reduce the amount of time your
lights are on.
-
Use task lighting; instead of brightly lighting an entire room, focus
the light where you need it. For example, use fluorescent under cabinet
lighting for kitchen sinks and countertops.
-
Consider three-way lamps; they make it easier to keep lighting levels
low when brighter light is not necessary.
-
Use 4-foot fluorescent fixtures with reflective backing and electronic
ballasts for your workroom, garage and laundry areas.
-
Consider using 4-watt mini-fluorescent or electro-luminescent night
light. Both light are much more efficient than their counterparts. The
luminescent lights are cool to the touch.
-
Use compact fluorescent lamps in all portable table and floor lamps in
your home. Consider carefully the size and fit of these systems when you
select them. Some home fixtures may not accommodate some of the larger
compacts.
-
For spot lighting, consider compacts with reflectors. The lamps range in
wattage from 13-watt to 32-watt and provide a very directed light using a reflector
and lens system.
-
Take advantage of daylight by using light-colored, loose-weave curtains
on your windows to allow daylight to penetrate the room while preserving
privacy. Also, decorate with lighter colors that reflect daylight.
- If you have torchier fixtures with halogens lamps, consider replacing
them with compact fluorescent torchieres. Halogen lamps generate excessive
heat that can create fire hazards. Compacts are cooler, use 60% to 80% less
energy and can produce more light (lumens) than the halogen torchieres.

Here's a simple comparison for two types of bulbs giving off the same
amount of light and burning for four hours per day for three years (4,380
hours). You'll go through six incandescent bulbs during this period, while the
compact fluorescent will still have another 3.8 years of life left.

It's A Fact:
If every household in the U.S. switched to Energy Star light fixtures,
we could save 70 billion kilowatt-hours and prevent 100 billion pounds of
CO2 per year -- equivalent to removing 10 million cars from the
road!
