Appliances may be the largest objects in a house and the most visible signs of electricity consumption, but today's typical household uses a constant flow of electricity to power all the gadgets and conveniences that have become, for many of us, a way of life. There has been growing awareness and discussion of the continuous drain on electricity that happens even when you think you've turned a system "off." Many standard items go into a low-power or standby mode when you click "off" - which means they continue to use power.

The Chicago Tribune recently ran an article entitled "Putting a plug on the drain gang: The electricityslurpers in your techno home," which offers eye-opening statistics on what is often termed vampire power. The problem is also referred to as
This Science Buddies science fair project idea moves beyond the discussion and gives student a blueprint for recording and measuring the impact of phantom power.
