When not in use appliances can still use energy. The US Department of Energy (USDOE) estimates about 5% of your household electric bill is spent on vampire loads that go to keep your electronics and other appliances ready to be used at a moment’s notice. That is about 425 kWh/year or $70/year or 225 pounds of CO2/year for the average household.
Want to find the vampires lurking in your home? Try a “Kill-A-Watt” meter that allows you to monitor a the energy a device is using even when turned off or shutdown.

One way to manage vampire loads is to use advanced power strips (APS). The USDOE estimates that a homeowner could save $200 per years using APS. Visit https://www.energy.gov/energysaver/articles/choose-right-advanced-power-strip-you for help in choosing the right APS
