5、V is always partially on, staying ready to flicker(闪烁) 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.

6、at approximately 5 percent of residential electrical power consumption in the United States is used for standby power.

7、at 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 l0 devices in a typical home, and the scope of the savings could be greater

8、than it may seem.Switch Off Equipment Not in UseFor many years manufacturers had no incentive to increase the energy efficiency of electronic devices that use standby power.

9、ny electronic equipment you purchase new will likely yield an energy improvement over something that has a few years on it.A good solution to deal with standby power losses in existing equipment is to plug several of the devices into a power strip that has an on/off switch. Power strips are inexpens

10、ive and available at home centers and office supply stores. An entire cluster of items can then be shut off-really shut off-just by flicking one switch.
