How Much Energy do Your Household Items Use? [Infographic]

By Jessica Bivins, April 9, 2018, Energy Efficiency

Saving energy (and money) is always easier when you know how much you’re using. But because many of the convenient smaller appliances we use seem to draw small amounts of power, we all too often discount how their use really does impact our electricity bills. With our How Much Energy Does This Appliance Use? series, we’ll examine what’s watt in small appliances to see approximately how much they use. To help you understand very basic electrical consumption calculations, you’ll need to keep a simple equation in mind: Volts (V) x Amperes (I) = Watts (W). What you’ll discover is how just how small appliances can contribute to your home’s energy usage and how these little conveniences can make big differences on your bill.

Your electronics and appliances provide ease and convenience in your everyday life, but they also contribute to your monthly electricity bill. While some appliances are relatively inexpensive, others can make up a surprising portion of your bill. With both lower and higher-wattage items, regular use can add up.

We take a look at your smartphone charger, coffee maker, aquarium, hair dryer, and refrigerator and calculate how much energy each of these use in a month, as well as how much it costs to use them.

Learn how to calculate your electronics’ energy usage:

Watts Used x Hours in Use = Watt-hours (.001 kWh)

Sample costs for a few common devices based on a 10 cent per kWh fixed rate plan include:

  • Smartphone Charger: $0.06/month
  • Coffee Maker: $7.30/month
  • Aquarium: $12.70/month
  • Hair Dryer: $0.45/month
  • Refrigerator: $16.20/month

How Much Energy Do Your Household Items Use?

 

The answers may surprise you.

 

Smartphone chargers consume between 15 and 20 watts when plugged in. If you charge your phone with a 20-watt charger for one hour everyday, it will use 600 watt-hours, or 0.6 kWh. This costs 6 cents per month. Cheap charging – just remember to unplug the charger when not in use!

Coffee makers of average full-size use about 730 kWh per year or about 61 kWh per month, costing about $6.10 per month. Single use pod coffee makers keep hot water on standby, costing about an extra $5 per month.

Aquariums operating costs can vary significantly by tank size, the presence of water plans and the needs of specific fish species. For example a 30-gallon tank would cost you about $12.70  a month.

Hair dryers use around 1,875 watts to generate heat and blow a powerful stream of air. Since you only use a hair dryer for about five minutes, it consumes about .156 kWh at a cost of about 1.5 cents. Used everyday that comes to about 45 cents a month.

Refrigerators on average use about 225 watts to cool your food. Assuming your refrigerator is on all the time, you will use about 5.4 kWh per day. That adds up to 162 kWh per month, costing $16.20.

When you embrace the convenience of your electronics, make sure you stay savvy about how much energy they use. The more educated you are about your household items and their effects on your energy bill, the more you can save!
