Top 10 summer energy-saving tips

Set your air conditioner thermostat as high as comfortable – we recommend 78º or higher when you're home. Use a smart thermostat to automatically adjust the temperature.
Have your central air conditioner tuned up and clean or replace filters monthly for efficient operation.
Keep blinds and curtains closed during the day. Open windows during cooler evening hours.
Use ceiling and portable fans to stay comfortable.
Minimize indoor heat in the afternoon: run the dryer and dishwasher at night on hot days and let your dishes air dry. Use a microwave, toaster oven or outdoor grill instead of the oven.
Set your water heater to 120º and use efficient showerheads.
Wash clothes in cold water and clean the lint filter in the dryer after every use.
Unplug appliances and electronics when not in use. To make it easier, plug home electronics, such as TVs, DVD players and computers into advanced power strips.
Remove, or unplug, extra freezers or refrigerators if you can, especially if they spend the summer outdoors or in a garage.
If you have a pool, consider upgrading to a variable speed pool pump to save on energy costs. Also be sure to keep the intake grates clear of debris.
