TWILIGHT:  "The Electricity Vampires in Your Home"

They are lurking in your home, and they attack while you are sleeping, when you leave . . . well basically, they attack all the time.  It's the devices which continue to suck power, even when you have their switches turned off.  But are these really a big deal when it comes to energy savings?  Or are "energy vampires" just an urban myth?

Turning off your computer when it is not in use is a great way to save energy.  But did you know that even when the computer is switched off, it can still continue to suck electricity from your electrical outlet?  This phenomenon of energy still being consumed when appliances or gadgets are turned off is called "vampire power," or sometimes "standby power" or "energy leaks."

Does My Home Have Electricity Vampires?
There are two simple ways to see whether your appliance is drawing vampire power:

•  If when you switch off the appliance or gadget there is a lit display on, then your gadget is drawing vampire power. This can typically happen with your television, computer monitor, DVR or phone charger.

• Another simple way to find out if your appliance, charger or gadget is drawing vampire power is by placing your hand on it when it is switched off.  If it feels warm to the touch, then it is drawing in energy and wasting it as heat . . . the vampire is striking!  

Maybe you have already been hearing about this phenomenon, and are wondering if it is really such a big deal, or if it is all hype and urban myth?  Well, the answer is that the impact of each appliance is relatively small, but when you add them all up . . . and remembering that they are all pulling power 24 x 7 . . . that the total cost of this vampire power can quickly add up.

It has been estimated that standby power use in the U.S. accounts for about 5% of total residential use.  This amounts to about 4 billion dollars a year in wasted standby power!   

Typical Vampire Power Costs
Shown below is a list of typical household appliances along with the annual cost you could be wasting by leaving them plugged in when they are not in use (the list was created by The Conscious Consumer along with the Lawrence Berkeley National Laboratory and the American Council of Energy-Efficient Economy, and it assumes electricity cost of 11 cents/kwh):
