What is the Duke Energy Saving Store?

The Duke Energy Savings Store is an online marketplace that offers Duke Energy residential customers energy savings products. The store offers energy efficiency products at discounted prices to provide you even more savings.

Why is Duke Energy offering energy savings products?

The Duke Energy Savings Store is one of many efforts to provide customers the tools to make a real difference in their energy use and costs.

We understand how important your time is which is why we are offering a quick and easy way to purchase energy savings products at discounted prices.

The environment also benefits from increased use of energy savings products. Helping our customers use less energy reduces the need for Duke Energy to run older, less efficient power plants and can also help delay the need to build new plants. Watch this video to learn more.

What types of energy-efficient products are available in the store?

The Duke Energy Savings Store will offer discounted CFL (compact fluorescent light) and LED (light-emitting diode) products. The types of bulbs offered vary based on size, shape and application. Product mix consists of reflectors (i.e. recessed), globes, candelabras, capsules (i.e. A-Lamps), three-way, dimmables and bare spirals.

Additional energy-efficient products will be included in the near future.

How are these energy-efficient bulbs better than traditional incandescent bulbs?

Traditional incandescent bulbs use a lot of energy to produce light. In fact, 90 percent of the energy is wasted as heat. That lost energy is money thrown away. Energy-efficient bulbs, such as CFLs and LEDs, last significantly longer than traditional bulbs, so you won't need to replace them as often.

ENERGY STAR® CFLs last 10 times longer than traditional incandescent bulbs, and LEDs last up to 25 times longer.

Who's eligible for the offer?

Legacy Duke Energy residential customers in North Carolina, Kentucky, Ohio, South Carolina and Indiana with electric service provided by Duke Energy are eligible to participate in the program. Former Progress Energy customers are not eligible for this program.

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.

How much can I expect to save by using energy-efficient lighting?

Savings will vary depending on type of lamp (i.e. CFL, LED), cost of electricity, bulb lifespan and hours of operation. ENERGY STAR®-qualified light bulbs pay for themselves in about six months. Then they begin paying you back. Change one bulb, and save $40 or more over the lifetime of the bulb. Change five bulbs, and save $200 or more over the lifetime of the bulbs.

If every American home replaced just one light bulb with an ENERGY STAR®-qualified bulb, we would save enough energy to light more than 3 million homes for a year, save more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.

What are the best locations to install energy-efficient lighting?

You should place your energy-efficient bulbs in high-use areas, where the light will be on four hours or more a day.

What brand are the bulbs I will be receiving?

The bulbs are ENERGY STAR®-qualified and brand types vary depending on bulb type.

Are CFLs safe to use?

CFLs contain a very small amount of mercury sealed within the glass tubing-an average of 4 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.

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.

What should I do if a CFL breaks?

The EPA provides recommendations to dispose of broken CFLs at

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 at
