As summer continues, energy efficiency is important year-round to save money on your electric bill. When temperatures are hot, it is a key time to make small adjustments to manage energy use to help save and avoid bill surprises.
Tips to save energy and money
- Set your thermostat to the highest comfortable setting. Even a couple of degrees can help save energy and money. Keep in mind: Your system will run longer – using more energy – the hotter it is outside even if your thermostat setting never changes.
- Use cooler water for washing clothes. Switching your temperature setting from hot to warm can cut a laundry load's energy use in half.
- Run heat-producing appliances during cooler morning hours for additional savings.
- Close curtains and blinds on the sunny side of your home to help prevent the sun from heating your home.
- Operate ceiling fans in a counterclockwise direction in the summer, which pushes cooler air back down into the room.
Between June 23 and June 24, Duke Energy received support from more than 521,000 Carolinas customers enrolled in the company's customer demand response programs. This allowed Duke Energy to help manage peak demand during the warmest parts of the day.
