Tips to Cool Your Home & Save

What can you do to reduce energy use during peak hours?

Energy Upgrade California® encourages all Californians to initiate energy savings during the peak hours of 4 to 9PM, such as by:

  • Turning off all but essential lighting
  • Using less hot water by operating washing machines and dishwashers during off-peak hours or on cold water
  • Pre-cooling your home outside of peak demand hours
  • Setting the thermostat for your air conditioner at a higher temperature when it is running
  • Installing timers on electricity-consuming appliances such as electric water heaters, indoor and outdoor lighting, water recirculation pumps, and pool and spa pumps
  • Using timers to run appliances such as dishwashers, washing machines and ovens at non-peak times

Flex Alert Tips

Flex Alerts are voluntary calls for consumers to conserve electricity.

A Flex Alert is typically issued in the summer when extremely hot weather increases energy demand up to generation capacity. This usually happens in the evening hours when solar generation is going offline and people are returning home and switching on air conditioners, lights, and appliances. When the state’s power grid operator, California ISO, calls for a Flex Alert we have the opportunity to prevent more dire emergency measures, including rotating power outages, just by reducing our use!

Here are some helpful tips to save on your energy bill this summer! Make sure to sign up for Flex Alerts today.

Before 4 pm

  • “Pre-cool” your home by turning your A/C down to 72 degrees

  • Charge electric vehicles

  • Charge mobile devices and laptops

  • Run dishwashers, washing machines, and other major appliances

  • Set pool pumps to run in the early morning or late at night

  • Close blinds and drapes

Safety During an Outage

During a power outage here are some quick safety tips to follow:

Use a flashlight rather than a candle for light at night

If using a standby generator, follow these safety tips:

  • Turn off major appliances like dishwasher or A/C that were running when the power went out to prevent them from starting unexpectedly when power is restored
  • Unplug or turn off TVs, stereo, and game systems
  • Leave one light on so you know when power is restored

Supplies to keep on hand:

  • A flashlight with a supply of fresh batteries.
  • A portable battery-powered radio so you can keep up with the news.
  • A telephone that does not depend on electricity. Cordless landline phones will not function during an outage.
  • A supply of easy-to-prepare, nonperishable foods. This includes packaged snacks and bottled water and juices.
  • A wind-up or battery-operated clock.
  • A first-aid kit.
  • Consider battery-powered phone chargers!
