BUSINESS

Does your smartphone use more energy than a refrigerator? A recent report by the Digital Power Group claimed that an average iPhone uses more juice for battery charging, data use, and wireless connectivity than a medium-sized, ENERGY STAR refrigerator.

Here are half a dozen surprisingly power-hungry devices that may be feeding your electric bill. (National Geographic News)

Discussion Ideas

  • Read our activity “Choosing Energy-Efficient Appliances,” which explains the concept of energy-efficiency and how it is calculated. Review the essential questions:
    • What are some ways you use energy resources?
      • Some may be on the “energy hogs” list, many may not!
    • How can you find out which appliances are most energy efficient?
    • Can individuals or families make more energy-efficient decisions about “energy hog” appliances?
      • The NG News article provides some choices:
        • make sure to choose an ENERGY STAR set-top box and pool pump;
        • use a furnace fan with an efficient motor, such as a brushless permanent magnet (BPM);
        • don’t using game consoles to stream movies.
  • Follow step four of the activity and have students determine their energy consumption for one of the “energy hogs” listed in the article. Wattage is available on most devices, or on the manufacturer’s website. For really ambitious students with iPhones, read this through investigation, and check out the charts.

One response to “Energy Hogs: Are They Lurking in Your Home?

  1. That is crazy! I didn’t realize charging your phone or playing a video game could use up that much energy. One thing that most families could be more careful of is to turn their TV off when they aren’t watching it.
