Take a Simple Step to Save Energy and Money
Saving money and the environment can be as easy as changing a light bulb. One of the easiest ways to lower your energy bill is to replace your standard bulbs with compact fluorescent light bulbs (CFLs).
We’re committed to helping you use energy wisely. That’s why we’re sending a coupon for a free six-pack of CFLs redeemable at Walmart to all qualified South Carolina customers.
If every Duke Energy S.C. customer receiving this offer installs six CFLs, we will save enough energy to serve the power needs of 8,000 homes.
So far, we’ve had an overwhelming response, and inventory has been low as a result. However, the coupon redemption date has been extended to July 15, and you can substitute comparable GE CFL packages for the 13-watt six-packs. See your local participating Walmart store for details.
CFLs have improved greatly since they first came on the market. Redeem the coupon and see for yourself how GE soft white CFL bulbs cast a warm light for your home.
About this Promotion
Why is Duke Energy sending me this coupon?
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 meet electricity demand without great rate increases for building new power plants. And customers save even more when they participate in energy efficiency programs.

Energy Savings and CFLs
What are the energy savings?
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.
Where are the best locations for CFLs?
You should use CFLs in high use areas, where the light will be on four hours or more a day.
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.
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 drop 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.
