Check the door seals and gaskets on the refrigerator and freezer to ensure they seal tightly.   Avoid putting hot foods directly inside the refrigerator or freezer. Let them cool to room temperature first if possible.   Keep the freezer full. A full freezer operates much more efficiently than an empty one and will stay colder longer in the event of a power outage. If the freezer isn't full, fill plastic containers with water and freeze them.   Decide what you want before you open the refrigerator/freezer door to prevent wasting energy.   Utilize smaller cooking appliances such as crock pots, microwaves and toaster ovens whenever possible.   Wash only full loads of dishes in your dish washer.     Wash clothes in cold water if possible to save heating large amounts of water.     Don't over-dry clothes. It saves energy and unwanted wear and tear on the clothing.     Cover spas and hot tubs and insulate around their sides and bottom to prevent heat loss.     Make sure your well pump is operating properly and not running continuously.       Use light bulbs best suited to their tasks, avoiding large bulbs where they are not needed.       Always make up water beds. The blankets provide insulation that prevents energy loss in the bed's heater. Heating and Air Water Heater Well Pumps Quick Tips
