|Also known as "Vampire Power" refers to the amount of electricity used by appliances or devices when they are in “standby” mode. Why is this significant? Well, it is estimated that anywhere from 7-15% of the electricity used in your home is for standby power. This is part of the reason why when you go away for a week or two, your electricity bill is still relatively high. (In addition to your heating, refrigerator, etc)
Taking this into consideration with the energy saving light bulbs, you may be save anywhere from 20-30% of your electricity bill by just changing your light bulbs and using power strips with your appliances that can be easily turned off when not in use. There are some new adapters that will automatically shut down standby current when appliances are not in use. So, if you are spending say $100 a month on electricity, you could be spending only $70-80 with the right changes.
