Different Heat Settings

• It takes energy to heat the air in a dryer. Therefore, settings that use less heat will also use less energy to create and maintain that heat.
  
  

Cool-Down Settings

• The "cool-down" or "perma-press" setting on your dryer uses cool air to finish the drying process. Even if your dryer's heat is set on high, you can save energy by adding the cool-down cycle to your drying cycle.
  
  

Time and Energy

• The dryer uses less energy to tumble clothes than it does to both tumble and heat them. However, it often takes clothes, especially heavier clothes like jeans and towels, a longer time to dry on lower heat settings. Prepare to wait a little bit longer for your laundry to finish, and know that the extra time has helped lower your energy consumption.
