Compact Fluorescent Light Bulbs
You've probably heard by now that one of the simplest things you can do to save energy is to start replacing your traditional incandescent light bulbs with compact fluorescent light bulbs (CFLs). They are a little more expensive than incandescents, but CFLs:
So why isn't everyone racing to replace all their old bulbs with CFLs? We discuss one reason here.
- use at least 75% less energy
- last up to 10 times longer
- save $30 over the life of the bulb in energy costs
- burn much cooler, reducing fire risk
A common argument against choosing compact fluorescent light bulbs over incandescent bulbs is that they contain mercury. It's true, they do, but by the time the bulbs have expired, a typical incandescent bulb is responsible for at least twice as much environmental mercury as a typical CFL.
Why? Because incandescents use about four times more electricity than CFLs, and burning coal for electricity is the main source of mercury emissions in the U.S. When coal is burned at a power plant, mercury is released into the air, and then is deposited either directly or indirectly into surface waters, such as oceans, lakes and rivers (where of course, it gets into the food web, of which humans are very much a part).
It is true that CFLs themselves do contain some mercury - on average, 4 milligrams per bulb, which is why they must be properly disposed of and not thrown in the trash (see next section for details). But what to do if one should break in your home or office? First, be proactive. Visit www.epa.gov and print out the Environmental Protection Agency's step-by-step instructions for cleaning up a broken CFL. Then, should you find yourself confronting a broken CFL bulb, remain calm, and consider the fact that a broken CFL releases at most 0.34 milligrams of mercury, and that OSHA's permissible mercury vapor in the workplace is 0.1 milligram per cubic meter (that's many times smaller than the average room).
Considering this, and the information in the next section, we hope you'll agree that there's no reason to choose the old incandescent bulbs over CFLs. If you decide to make the switch, start replacing the most frequently used light bulbs in your house with CFLs, and watch with amazement as your electric bill shrinks!
|Did You Know?
Some interesting tidbits about compact fluorescent light bulbs (CFLs):
- You can now recycle unbroken CFLs at all Home Depot locations; just give them to the store associate at the returns counter
- According to the Earth Policy Institute, if every American household
switched over to CFLs, the U.S. could close 80 coal-fired power plants.
|Myth Busters: Energy
Myth: Leaving a fluorescent light turned on is cheaper than turning it on and off.
Fact: Frequently turning a fluroescent light on and off does shorten the bulb's life somewhat, but so does leaving the bulb on all the time.
Fact: Modern fluorescent bulbs do draw a higher level of current during startup, but the surge usually lasts only about a tenth of a second and consumes about as much energy as five seconds of normal operation.
Good Rule of Thumb: Any fluorescent light should be turned off if it won't be used for five minutes or more.
