Are you wasting money and power without even being aware of it?
Many consumers are unaware that most of their appliances are actually consuming
power while they are switched 'off'. These appliances are drawing power 24 hours
a day, 365 days a year, often without one even being aware of it. This power
consumption is called "standby power" or "vampire power".
But this also means that these devices use energy even when they're turned off and are not actually being used. Individually, these functions don't consume a lot of electricity in standby mode, but add them together and these loads start to mount up. It is estimated that standby power accounts for approximately 10-15 percent of the average household's annual electricity consumption. In some cases, the cost of the standby power that is consumed by a device during its lifetime exceeds the cost of power used when actually running the device. For example, a typical microwave consumes, over its lifetime, more electricity powering its digital clock than it actually does heating food. Even though it may take 100 times more power to heat the food, the microwave is in standby mode more than 99% of the time. The same holds for many other devices such as TVs and stereos.
Unfortunately, most standby power is not consumed by remote devices and digital clocks, but rather by inefficient power supplies, and unnecessarily energized electronic parts that were inefficiently designed. The manufacturers usually have no concern for wasteful energy consumption nor for the consumer's high electrical bill. As technology advances, the list of devices that make use of standby power is unlimited. Stoves with clocks, A/C units, microwaves, VCRs, battery re-chargers, TV's, cordless phones, computers and computer gadgets, home entertainment centers, cordless tools, to name a few of the overwhelming array of devices that are being bought everyday, each making use of standby power.
