Why is Duke Energy offering this CFL promotion?

The U.S. Department of Energy estimates 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. Watch this video to learn more.

How do you determine how many CFL bulbs a person is qualified to receive?

Residential customers are eligible to receive CFL bulbs. The amount of bulbs that you qualify for depends on the number of CFL offers that you have previously participated in. Our records will indicate past participation and deduct from the maximum number of bulbs allowed for the campaign. The difference determines the number of bulbs eligible for the customer. The customer’s past participation may include coupons, K12 surveys, and other campaigns.

How much can I expect to save by using CFLs?

CFLs last up to 10 times longer than incandescent bulbs and use up to 75 percent less electricity than conventional incandescent bulbs. On average, each CFL will save about $40 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 $240 in energy costs.

What are the best locations to install CFLs?

You should use CFLs in high-use areas, where the light will be on four hours or more a day.

Are CFLs safe to use?

CFLs contain very small amounts of mercury sealed within the glass tubing—an average of 4 milligrams—which is 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.

Most makers of light bulbs have reduced mercury in their fluorescent lighting products. Thanks to technology advances and a commitment from members of the National Electrical Manufacturers Association, the average mercury content in CFLs has dropped at least 20 percent or more in the past several years. Some manufacturers have even made further reductions, dropping mercury content to 1 milligram per light bulb.

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. To learn more, visit the Environmental Protection Agency’s website.

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 website

What should I do if a CFL breaks?

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

What should I do with a CFL that burns out?

Virtually all components of a fluorescent bulb can be recycled. CFLs and other fluorescent light bulbs also contain very small amounts of mercury, so it is important to recycle them at the end of their lifespan. Because an ENERGY STAR® CFL lasts 10 times longer than a comparable traditional incandescent bulb, CFLs have to be recycled less frequently than most people are accustomed to. And most people are used to disposing of traditional incandescent bulbs in the trash. Many retailers recycle CFLs for free, and some municipalities have special recycling programs for CFLs. Please visit the EPA website for suggestions on recycling CFLs.

Why are some customers in Greenwood, S.C. not eligible for this offer?

In June 2009, a letter was mailed to all customers in Greenwood, S.C. who were on the old grandfathered Greenwood rate schedules explaining that they would not be eligible to participate in Duke Energy’s Energy Efficiency Products and Services. The Energy Efficiency Programs are funded through a small monthly fee on customers’ bills. Because we are unable to charge the fee on the Greenwood rate, these customers will not be eligible to participate.

Why are business customers not eligible for this offer?

This current offer is for residential customers only. We anticipate there will be opportunities for our business customers to participate in future lighting offers.
