Understanding Which Home Appliances Use the Most Energy

Have you ever stopped to consider how your bill's total came to be?

Every month you run your appliances as you need them, and at the end of the month you pay your monthly energy bill. It's simple. But have you ever stopped to consider how your bill's total came to be?

Your bill is a product of all your appliances' energy usage for the month, and while some appliances use a relatively small amount of electricity, others consume thousands of watts.

Below is a brief example of the energy usage of common appliances, starting with the largest users. The goal is to give you a better idea of what you're paying for and where energy is costing you the most.

  • Central AC: 6,000 watts
  • Electric clothes dryer: 6,000 watts
  • Heat pump: 5,000 watts
  • Tea kettle: 1,500 watts
  • Window AC unit: 1,300 watts
  • Coffee maker: 1,200 watts
  • Vacuum: 1,100 watts
  • Iron: 1,000 watts
  • Toaster: 1,000 watts
  • Garbage disposal: 400 watts
  • Furnace fan: 400 watts
  • Blender: 300 watts
  • Halogen lamp: 300 watts
  • Computer: 250 watts
  • Electric blanket: 250 watts
  • Heat lamp: 250 watts
  • Dishwasher: 200 watts
  • Mixer: 200 watts
  • Crock pot: 150 watts
  • Flat-screen TV: 150 watts
  • Flood light: 150 watts
  • Humidifier: 90 watts
  • Ceiling fan: 60 watts
  • DVD player: 25 watts
  • Fluorescent lamp: 20 watts
  • These figures represent an example of the average amount of electricity used over the course of a month, and it is very possible for numbers to fluctuate depending on your living situation and even where you live. For example, homes in warmer climates will probably spend more on their air conditioning than homes in cooler locations. It's also important to remember that many appliances such as televisions and computers will use electricity even when they are not turned on. Simply being plugged in is enough to draw electricity and waste watts.

    You can lower your overall watt usage by turning appliances off and unplugging them when not in use. You can also save money by replacing older, inefficient appliances with Energy Star alternatives. Doing so will lead to a decrease in watt usage and, best of all, a lower monthly bill.
