Standby power, also called vampire power, vampire draw, phantom load, or leaking electricity, refers to the electric power consumed by electronic appliances while they are switched off or in a standby mode. A very common "electricity vampire" is a power adapter which has no power-off switch. In study’s performed by the Lawrence Berkeley National Laboratory indicated that Standby power consumption accounts for approximately 10% of total residential electricity consumption in America, adding up to more than 3 Billion Dollars in annual energy costs. Some such devices offer remote controls and digital clock features to the user, while other devices, such as power adapters for laptop computers and other electronic devices, consume power without offering any energy saving features.
