A home’s hungriest energy consumers are the appliances left running all day or for days at a time. Here’s a look at the top 5 electricity eaters and some tips on how to stave off their appetites:
The Number 1 home energy hog is the heating system. Ways to control your heater’s energy consumption include using a programmable thermostat, upgrading to a more efficient unit, sealing ducts and replacing filters.
Next up is the cooling system. You can improve the efficiency of your air conditioner by having a technician service it every year, using a programmable thermostat and ensuring adequate attic insulation.
Third is the water heater, which can account for up to 12% of a home’s energy bill. Actual energy demand for water heating depends on the model of water heater you have. Yet no matter the type of unit, these habits can help you conserve: taking quick showers, washing clothes in cold water, setting the water temperature to 120 degrees, insulating the storage tank, and regularly draining sediment.
Next on the list are dehumidifiers, which typically run constantly to discourage mold growth and preserve stored items. To make sure your dehumidifier isn’t wasting energy, close off the room where the machine is operating, set it at a reasonable level and consider upgrading to an energy-star certified model.
Fifth on the list—but still major power users—are refrigerators and freezers. Fridges generally are the top-consuming kitchen appliances, especially those that are a few decades old. Regardless of model, you can save energy by setting the temperature to 36 to 38 degrees for the refrigerator and 0 to 5 degrees for the freezer, discarding freezer ice thicker than a 1/4 inch, checking seals, and cooling hot food before putting it inside.
