Stoves & Ovens: Use & Care
Use & Care
Efficient Cooking Skills
You can save energy in the kitchen by adjusting how you use your cooking appliances. Focus on stove and oven use, choose the proper cookware, and take advantage of energy-efficient cooking appliances and techniques.
Put a Lid on It
You can decrease energy use with your stove by up 66% by using pot lids, allowing you to set lower temperatures on the stove while cooking.
Match Burner & Pot Sizes
Match pot size to burner size, using the smallest possible pot. If using gas, make sure the flame doesn't reach around the cookware.
Keep Burners Bright
Keep your burners’ grease plates clean or line them with aluminum foil. This helps to increase energy efficiency by reflecting heat upward.
Save Water, Save Energy
It takes a lot of energy to heat water, so use just enough to get the job done.
Cookware: The Right Stuff
Use the proper cooking tools for the kind and amount of food you are cooking. Toaster ovens, crock pots, pressure cookers, and electric kettles may be a better choice than your oven or stove. This table shows cost and energy use by appliance.

Defrost food in the fridge before cooking in the oven.
Turn off the oven or stove heat a few minutes before the designated time. Your cooking appliance will retain the same temperature without investing more energy into heating itself, and food will continue to cook until the unit cools down.
Your oven’s temperature drops about 25° F every time you open the door while cooking.3 Save energy on oven heating and air conditioning by not peeking.
Start your oven’s self-cleaning function immediately after baking something—so you don’t have to heat up a cold oven. You also save energy by not using the self-cleaning function more than once a month.
With a conventional oven, only preheat for the designated time.
