Duke Energy shares ways to save energy and money as temperatures plunge next week

• Customer tools and tips are available to manage energy use and bills as temperatures drop below seasonal norms

CHARLOTTE, N.C., Dec. 12, 2025 /PRNewswire/ -- With frigid temperatures forecast to arrive early next week, Duke Energy is committed to helping customers save energy and money as heating systems work harder to combat the cold. By acting now, customers can take more control of their energy use – even as temperatures drop well below freezing.

Simple actions, more savings

• Set your thermostat to the lowest comfortable setting. Every degree lower means more money in your pocket, without sacrificing comfort.
• Seal leaks and insulate. Prevent cold drafts and keep warmth inside – saving energy and reducing heating bills.
• Change air filters regularly. Clean filters improve airflow and system performance, reducing energy consumption and keeping your home more comfortable.
• Let the sun help heat your home. Open blinds and curtains on sunny days to naturally warm your space, and then close them at night to keep the heat in.
• Operate ceiling fans clockwise in winter. Push warm air down for greater comfort.
