70 watts of energy being used by my home entertainment system when it’s turned off!

March 29, 2008

Yesterday I got a device that measures how much electricity an appliance uses. Instead of plugging the appliance into the wall, you plug it into this device, and then the device into the wall. Turn on the appliance and the device shows how many watts are being used by the appliance.

I was particularly interested in knowing how much energy my entertainment appliances use when they are “off”:

  • stereo
  • DVD
  • VCR
  • cable box for cable TV

I plugged all these appliances into a power strip, plugged the power strip into this device, and then plugged the device into the wall.

With all of the appliances turned “off” (i.e. the TV is off, the stereo is off, the DVD and VCR are off) the device showed 70 watts of power being used. Wow! That’s a lot of energy being used with absolutely no benefit. That’s like running a 70 watt light bulb 24 hours a day, 365 days a year, in a closet.

From now on, I will turn the power strip off when I am not using my home entertainment system.
