Xcel Energy Summer Conservation Tips 

Xcel Energy is offering some tips to help customers find relief from the heat and their bills during summer. Home cooling can account for about half of a summertime electric bill. There are small changes customers can make in their day and evening routines to save money, including setting thermostats to 78 degrees or higher if your health allows, turning off unnecessary lights and postponing the use of major appliances until after 8 p.m.

Xcel Energy also offers a full selection of programs and rebates to help businesses save energy and money. View the options on their Smarter Energy Use for a Better Business page.

Additional summertime energy-saving tips include:

  • Using electric fans instead of air conditioning when practical
  • Closing drapes and blinds to keep out direct sunlight during hot periods
  • Avoiding using evaporative coolers or humidifiers at the same time an air conditioner is running
  • Operating energy-intensive appliances, such as dishwashers, washing machines and dryers during early morning and late evening hours
  • Limiting the opening and reopening of refrigerators, which are major users of electricity in most homes
  • When possible, businesses should shift power-intensive work processes to morning or late evening hours
