Conserving Energy While Staying Cool:
The Los Angeles Department of Water and Power (LADWP) is ready to respond to any potential power outages in Los Angeles and will work around the clock to meet customer demand. Angelenos are reminded to conserve energy use where possible as demand for electricity may increase as customers run air conditioners. LADWP recommends the following to conserve electricity safely while helping reduce any potential strain on neighborhood electrical infrastructure:
Adjust air conditioning thermostats to 78 degrees. If you are away from your home and do not have pets inside, turn off the air conditioning system.
Limit the use of major appliances such as washing machines, vacuum cleaners, and dishwashers to before 4:00 PM or after 9:00 PM.
Ventilate your home in the early morning and evening by opening windows and doors to clear out the heat and allow cooler air to circulate. Close curtains, shades or blinds during warmer hours to reduce heat from direct sunlight.
Turn off lights and other electrical equipment when not in use.
Unplug energy vampires like cellphone and computer chargers, and other appliances that use energy when not in use.
Avoid using the stove and oven if possible, which can help keep indoor temperatures down.
