You probably don’t even realize it, but an energy thief is inside your home at this very moment. This thief is silent and unseen, and he’s picking your pocket. His name is "standby power." Standby power is the name given to the electricity used to power electrical appliances and devices even when they are turned off. But how can this be Isn’t an appliance "off" when you switch it off Not necessarily.
Many electronic devices consume electricity 24 hours a day just to stay warmed up for whenever you decide to use them. "Instant on" TV sets are one example. Whether you watch TV seven hours a day or not at all, the TV is always partially on, staying ready to flicker to life the moment you turn on its switch.
Other devices that consume power constantly are those that have external or internal clocks: microwave ovens, computers, VCRs, DVD players, and cable TV and satellite TV boxes. Energy experts estimate that approximately 5 percent of residential electrical power consumption in the United States is used for standby power. That’s a lot of power plants running overtime just to keep our electronics warm and ready to go.
Some of the most prevalent standby power devices are the large plug—in transformers that are used to step down power to cordless phones and answering machines. How much do these various devices consume Not much; just a few watts, maybe 3 to 5 each. But multiply that number over a 24-hour day, times the 6 to 10 devices in a typical home, and the scope of the savings could be greater than it may seem.
Which of the following is true about standby power

A:It makes up five per cent of all electricity consumption in the United States. B:Electrical devices that have internal or external clocks consume standby power. C:Standby power is not of significance compared to the whole consumption of electricity. D:Standby power is important to maintain the normal functions of electrical devices.
