Why is Duke Energy promoting CFLs?

The U.S. Department of Energy projects that the demand for electricity will rise 40 percent by 2030. Keeping up with this demand will be difficult and building new power plants is expensive. When customers are able to conserve energy, the financial return on the electricity saved is nearly as much as the cost to build a new power plant. Energy efficiency means Duke Energy can meeting electricity demand without great rate increases for building new power plants. And customers save even more when they participate in energy efficiency programs.

What are the energy savings associated with using CFLs?

CFLs last up to ten times longer than incandescent bulbs and use up to 75 percent less electricity than incandescent bulbs. On average, each CFL will save about $30 in energy costs over the expected lifetime of the bulb. By changing out the six most used bulbs in your home to CFLs, you could save over $180 in energy costs.

I've heard that CFLs are not safe. Do CFLs contain mercury?

CFLs contain a very small amount of mercury sealed within the glass tubing – an average of 5 milligrams – about the amount that would cover the tip of a ballpoint pen. By comparison, older thermometers contain about 500 milligrams of mercury. It would take 100 CFLs to equal that amount. The mercury is held within the bulb and is not released unless the bulb is broken.

All CFLs provided through Duke Energy’s optional program are UL and Energy Star rated and should be used and disposed of by customers in accordance with the manufacturer’s instructions. Unlike traditional incandescent bulbs, CFLs may flicker, dim and emit an odor or smoke at the end of their lives.

Mercury currently is an essential component of CFLs and is what allows the bulb to be an efficient light source. No mercury is released when the bulbs are intact or in use. Many manufacturers have taken significant steps to reduce mercury used in their fluorescent lighting products. In fact, the average amount of mercury in the new smaller styles of CFLs has dropped to around 1.5 milligrams thanks to technology advances and a commitment from members of the National Electrical Manufacturers Association.

What precautions should I take when using CFLs in my home?

CFLs are made of glass and can break if dropped or roughly handled. Be careful when removing the bulb from its packaging, installing it, or replacing it. Always screw and unscrew the lamp by its base (not the glass), and never forcefully twist the CFL into a light socket. If a CFL breaks in your home, follow the clean-up recommendations below. Used CFLs should be disposed of properly (see below). To read more, visit the Environmental Protection Agency’s Web site.

What should I do if a CFL breaks?

Duke Energy recommends following the EPA guidelines for disposing of broken CFLs.

What do I do when a CFL bulb burns out?

The EPA recommends that consumers take advantage of available local recycling options for CFLs. Many large retailers, such as Home Depot and Lowes, offer recycling programs for CFL bulbs.

The business reply card does not include my name or address information. How will Duke Energy identify me and ship the CFLs to my home?

This ensures customer privacy and allows us to process the cards quickly by scanning the barcode. The bulbs must be installed at the service location that corresponds to this Duke Energy account.

I have a CFL that produced a very unpleasant odor and some smoke when it failed. Is it hazardous?

Most CFLs do not produce an odor or smoke when the CFL reaches its normal end of life. However, CFLs, like many electrical or electronic products, can sometimes fail in a way where one of the electrical components or plastic materials will briefly produce a very irritating odor and possibly some smoke. Any smoke or odor produced is in a low concentration, which will not result in a hazard. However, in the relatively small number of cases where this might occur, it can produce a very pungent smell that is certainly not pleasant. If this situation occurs, the easiest way to eliminate any odor is to follow the same approach that one would use to eliminate any other unpleasant odor or smell. Briefly leave the immediate area if it is very irritating. Next, after waiting 10 or 15 minutes, air out the room by opening any doors or a window if there is one. This will quickly dissipate the remaining fumes or smell. If available, a normal portable household fan or ceiling fan will accelerate the process.
