How you can save energy during hot weather

These easy DIY tips can help save energy and keep costs down


We can't do anything about the weather, but we can adjust our energy use during extreme temperatures. When it’s hot outside, we want to cool down. So for starters, reduce activities that generate heat, such as burning open flames, using hair dryers or cooking on the stove or baking in the oven.

These are some easy ways to keep cool and reduce your energy use during warm weather.


Set thermostat higher: When it’s hot outside, set your thermostat to the highest comfortable setting. The higher the setting, and the smaller the difference between the inside and outside temperatures, the lower your energy costs will be. A programmable or smart thermostat makes it easy to set a schedule that works for you.


Run dishwasher when it's cooler: Choose an energy-saving cycle and air dry or overnight dry setting. Run only full loads and during cooler parts of the day, such as early morning and late evening. Avoid the pre-rinse cycle. The rinse hold setting uses 3 to 7 gallons of water.


Use LED lightbulbs. Replace standard bulbs with light-emitting diodes (LED). LEDs are more efficient than regular bulbs, while giving off the same amount of light.


Spin the ceiling fan counterclockwise. By using a ceiling fan, you’ll feel cooler and be able to raise the thermostat by as much as 4 degrees Fahrenheit. The counterclockwise direction combined with the blade pitch creates downdraft, ..


Change air filters regularly. A clogged, dirty air filter makes an HVAC system work harder, which uses more energy. Dusty conditions or pet fur could require more frequent replacements. Change air filters once a month, or at least every three months.


Get HVAC inspected. Have the HVAC system checked to maintain performance. An air conditioner's filters, coils, and fins require regular maintenance to function effectively. Duke Energy offers qualified customers rebates to help offset the cost of replacing older units with energy-efficient ones.

Grill outdoors. Cooking in the oven or stovetop will heat up the kitchen. Grill outside to keep the heat outdoors. You’ll also save energy by cooking in the microwave instead of in the oven.  


Seal leaks. Look for gaps around pipes and the foundation. Check to see if the caulking and weather stripping has deteriorated. Seal leaks around doors, windows, cracks and openings to keep hot air from entering your home. Use caulk or weatherstripping to seal air leaks.


Close the blinds. Close blinds and curtains on sunny days. If you have a whole-house fan, use it to pull cool air into your home at night or in the early morning through open windows. Turn the fan off and shut the windows during the day.


Use the washer and dryer efficiently. Wash full loads of clothes in cold water. The detergent cleans the clothes not the water temperature. Use the dryer during cooler parts of the day. Clean the lint filter after every load, which will help clothes dry faster and save energy.


Unplug. Unplug electronics like phone chargers and laptops when you’re not using them. Leaving them plugged in wastes small amounts of energy that can add up. If you’re going on vacation, you’ll save by unplugging appliances while you’re away.
