Reducing Phantom Energy
By Betsy Bennett-Stacey, Curator
Have you heard the terms “phantom energy,” “ghost draw,” or “vampire appliances”? These terms refer to the electricity that many appliances and electronic devices use even when they appear to be turned off. Computers, microwaves, coffeemakers, TV’s, and cable boxes, for example, often draw small amounts of energy even when turned off to power digital displays and standby modes. Gadgets that use rechargeable batteries and plug-in adapters are some of the most aggressive “vampires,” because the adapters draw power even when the gadgets themselves aren’t plugged in.
Phantom energy use really adds up- and is growing all the time. In the US phantom energy reportedly cost consumers more than 45.8 billion dollars a year, generates more than 87 billion pounds of atmospheric CO2 a year, and accounts for 5-10 percent of household electricity useage.
What can you do about phantom energy?
• Plug appliances into a power strip and switch it off when finished for the day.
• To find out how much energy your appliances “secretly” use, purchase a Kill-a-Watt or similar product. You can also borrow a Kill-a-Watt meter from The Grafton Library or The Nature Museum. This device can calculate consumption for an individual appliance by the hour, day, week, month or year.
• For a small investment, purchase a product like the Smart Strip Power Strip or the WattStopper. They “know” when an appliance is being used and disconnect the power when it is not. This is great for bundled electronics like your computer, printer and scanner.
• When buying a new appliance, consider energy usage. The Federal Energy Management Program endorses an online dartabase of appliances and phantom energy use: http://oahu.lbl.gov/cgi-bin/search_data.pl.
• Finally, perhaps the best advice is to keep it simple. When buying appliances and gadgets, consider if you really need all the extra features, those extra features may come with secret energy needs.
The bottom line: By reducing phantom energy use, you’ll lower your electric bill and your carbon emmissions.
