If you live in a climate where it cools off at night, turn off your cooling system and open your windows while sleeping. When you wake in the morning, shut the windows and blinds to capture the cool air. Learn more about natural ventilation.
Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
Turn off ceiling fans when you leave the room. Remember that fans cool people, not rooms!
Cool off in the pool. An energy-efficient pool pump can use up to 70% less energy than a standard pool pump. SDG&E is offering a $200 pool pump rebate.
Avoid placing lamps or TV sets near your room air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
Monitor your energy use. Go to My Account to check out the Energy Management Tool and sign up for energy alerts to receive email or text alerts when your energy use or spending goal reaches a certain limit.
