Energy Vampires Consumer Electronics
• Be aware of “energy vampires”Vampire energy is a type of energy used by things that consume electricity twenty-four hours a day, even when you think you have turned them off! – TVs, VCRs, DVD players, computers/printers, stereos, microwaves,
coffee machines, washers/dryers, rechargeable power tools, etc. are the everyday secret users of vampire energy.
– A TV with a remote could use more energy during the 20 hours it is turned off waiting for you to turn it on than it does while you are watching it for 4 hours in the evening.
– Vampire energy amounts to about 5% of energy consumed in the United States and usually costs consumers more than $3 billion each year.
