What is electric ghost power?

Answer 1

This is also known as phantom power or vampire power. Even though an electric device is turned off, it is still drawing a small amount of power. A television, for example, continues to draw power so that it can sense the remote control to turn it on, or to keep the time.

Other examples are chargers left plugged in for telephones, Video Games, etc.

Answer 2

Ghost electricity, often called vampire power, phantom power, or idle current, is power wasted by devices when they're not in use or even turned on. Often, unused devices left plugged into your wall outlet contribute to higher electric bills.
