75% of the electricity used by electronic appliances is consumed while they are turned off . This means that you waste as much as $400 of energy each year even without using these appliances. How? …
As per the U.S. Department of Energy - "Many appliances continue to draw a small amount of power when they are switched off. These "phantom" loads occur in most appliances that use electricity, such as VCRs, televisions, stereos, computers, and kitchen appliances. In the average home, 75% of the electricity used to power home electronics is consumed while the products are turned off. This can be avoided by unplugging the appliance or using a power strip and using the switch on the power strip to cut all power to the appliance."
Ghost loads or Phantom loads are electrical devices that continue to draw power when supposedly "off". One recent study showed that ghost loads account for approximately 7% of the electricity used in the U.S. or sixty four million megawatt hours, costing over three billion dollars worth of energy. The reason many appliances still draw power when supposedly "off", is because they are put on standby and not switched off completely. Standby means that the part of the circuitry is still using power. This is a 100% unnecessary waste of energy.
How to identify ghost loads?
If you are doing this exercise at home, you can use a “kill a watt” power meter. Connect a appliance through this meter to the power supply. If you find that an appliance is using more than a watt or two when in standby, it is a ghost load.
In large setups, like a commercial building, you can track energy consumption with an energy tracking software - like ioEYE Energy. You can use energy consumption graph to identify always on power and the ghost loads.
How to reduce ghost loads and save energy?
Switch off the equipments power supply when not in use, instead of being lazy and just switching it off with the remote. You can save as much as $400 per year on your electricity bill by getting rid of phantom loads, according to the U.S. Department of Energy. Like switching off printers when not in use can save up to 11kwh of energy in a year.
