I think by ghost electricity you're referring to phantom loads which refers to devices that draw power even when they're off. Think about a TV for example. When you turn it off you're not really turning it, but just putting it in standby mode. There has to be a minimal amount of circuitry powered up to be able to turn it on using the remote control. It's a small amount, but still not zero.
