Duke Energy helps customers estimate cost of holiday lighting, gives tips for energy savings

Holiday lights are up across the country, bringing bright colors and welcome cheer. To help customers plan and manage their light displays, Duke Energy offers a holiday lighting energy calculator that estimates holiday lighting costs.

Holiday lighting calculator:

Users can identify the type of lights, the number of 100-bulb strands and how many hours the lights will be used per day to estimate the energy cost per day and per month. Based on their lighting selections, customers can receive energy-efficient tips and options.

For example, six 100-bulb sets of large, incandescent bulbs (600 bulbs total) plugged in six hours each evening can add about $75 to a monthly power bill. By comparison, six 100-bulb sets of similarly styled light-emitting diode (LED) bulbs would increase a monthly power bill by only about $5. Using six 100-bulb sets of mini-LED bulbs would increase a monthly power bill by only 72 cents.

Money-saving tips to combat the cold

As the holiday season heats up, temperatures will cool down. Help save on winter energy bills with the following tips:

  • The thermostat can be the biggest contributor of high winter bills. Select the lowest comfortable setting on the thermostat when home and then lower the temperature a degree or two when leaving.
  • Change air filters regularly. A dirty air filter makes a heating system work harder, which uses more energy.
  • Inefficient heating can also add to monthly power bills during colder temperatures. Regular service calls from a licensed technician will help to properly maintain one’s heating and cooling system.
  • A ceiling fan is a great way to stay cool in the summer and warm in the winter. Simply set the fans to operate in a clockwise direction, which pushes warm air back down into the room, during winter months. Switch the direction during warmer months.
  • On sunny days, leave drapes or blinds open to allow the sun’s rays to warm the house.
  • Wear warm clothing for additional energy savings at home. If planning a holiday party this season, consider a holiday sweater theme. That way, as host, you can bump down the thermostat a degree or two while guests stay warm and toasty.
