Energy Conservation Needed as Extreme Heat Returns to California


The California Governor’s Office of Emergency Services is reminding Californians to take extra precautions to stay safe as another statewide heat wave is expected through Labor Day weekend. 

Excessive heat warnings have been issued by the National Weather Service (NWS) for successive days of extreme heat starting today and extending into Tuesday in impacted areas. According to the NWS, temperatures will peak near 110 degrees for much of the inland parts of the state.

Extreme heat presents dangerous conditions but can be limited with these helpful tips:

  • Avoid outdoor activities during the hottest part of the day, generally, 10 a.m. to 6 p.m. 
  • If outside, take frequent breaks in the shade or air conditioning
  • Stay hydrated
  • Check on elderly or vulnerable family members and neighbors 
  • Wear light-weight clothing 
  • Never leave children or animals alone in a vehicle 

Cal/OSHA issued a reminder to all employers with outdoor workers to take steps to prevent heat illness during a period of high heat across the state.

The California Independent System Operator (ISO) has also issued a statewide Flex Alert from 3 p.m. to 9 p.m., through Monday. Energy conservation can be done by:

  • Setting thermostat at 78° or higher 
  • Cooling with fans and drawing drapes 
  • Turning off unnecessary lights and appliances 
  • Using major appliances in the morning or late evening  

These conservation measures can help the power grid during a time of strong demand and supply. Reduced energy use during a Flex Alert can prevent further emergency measures, including rotating power outages.
