When temperatures dip across eastern North Carolina, many members are surprised to see their electric bills rise, sometimes sharply. Even in our generally mild coastal climate, winter weather can have a significant impact on home energy use. Here’s why colder months often lead to higher bills and what you can do to manage costs.
Heating Systems Work Harder in Cold Weather. Heating typically makes up the largest portion of a home’s winter energy use. When the temperature outside drops, your heat pump or electric furnace must run longer and more frequently to maintain the temperature you’ve set on your thermostat. This is especially true during periods of sudden temperature swings when a cold front moves in after several warm days. Homes cool quickly, causing your system to work overtime to catch up.
Heat Pumps Become Less Efficient at Lower Temperatures. Most homes in eastern North Carolina rely on electric heat pumps. They are very efficient in mild weather but lose efficiency as temperatures fall into the 30s and below. When it gets especially cold, heat pumps often switch to auxiliary heat, which uses much more electricity and can cause a noticeable jump in energy use.
Longer Hours Indoors Mean More Energy Use. Shorter days and cooler weather mean we spend more time inside. That often translates to:
- More lights turned on
- Increased use of TVs, gaming systems, and computers
- More hot showers and water heater use
- Additional cooking and holiday activities
Increased Use of Space Heaters. Portable electric heaters can help warm a small area, but they consume a large amount of electricity. Running multiple space heaters, or using them for long periods, can significantly increase your bill, even if your main heating system is running efficiently.
Homes Lose Heat Through Drafts and Poor Insulation. Even small air leaks around windows, doors, or attic hatches can let warm air escape and cold air in. If your home isn’t well sealed, your heating system must run longer to maintain comfort.
Tips to Help Manage Winter Energy Costs
- Lower your thermostat 1–2 degrees. Even a small adjustment can reduce energy use. The Department of Energy recommends setting your Thermostat to 68 ° during the winter months.
- Check filters monthly. Dirty filters make heating systems work harder.
- Seal gaps around windows, doors, and ductwork to keep warm air inside.
- Use space heaters sparingly and only in small, occupied rooms.
- Take advantage of sunlight. Open curtains during the day and close them at night.
- Monitor your energy use in PowerPay24 to spot spikes and better understand daily consumption.
Winter weather may be beyond our control, but understanding how seasonal changes affect energy use can help you take steps to stay comfortable and keep bills manageable.
