Prop open the door a bit after the cycle to air dry your load. If you have an electric cooktop, turn the burners off a few minutes before the allotted cooking time. The heating element will stay hot long enough to finish the cooking without using more electricity. Refrigerators Refrigerators use more power than any other appliance in the home and deserve special attention. Although rushing out to buy a new refrigerator may not be in your budget, it is important to know that new models are more efficient and use as little as half the electricity of older units.
Full refrigerators run more efficiently than ones that are only partially full.
So buy more food and save some energy. If you have two refrigerators, or an additional freezer, decide if the extra expense is really worth it. Cram as much as you can into your primary refrigerator or consider disposing of two older refrigerators and replacing them with one larger, newer and more efficient model. Make sure the refrigerator door seals are tight. If you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing.
