PORTLAND - Halloween is still days away, but energy vampires hiding in your home could be draining your wallet.
Appliances and electronic devices suck up energy even when they're turned off or not in use.
Armed with a tool called a Kill-A-Watt, a device that measures energy use, PGE took us around a home to test different electronics.
The biggest energy hog was the entertainment center.
“It looks like [the] entire system here is drawing about 28 to 29 watts … that’s going to be around $28 to $29 a year to operate,” said Garrett Harris, and energy specialist with PGE.
As a rule of thumb, one watt for one year equals $1, which means a house full of appliances and electronics can add up to hundreds of dollars wasted every year.
Energy experts say a good way to save money is to plug your electronics into a power strip and switch off that power strip when you're not using them.
You can also find out how much energy you’re wasting in your own home.
The Kill-A-Watt energy monitors are available for check-out at more than 50 libraries across Oregon.
