Reading some of the stuff here inspired me to do some research in regards to how all my appliances are working, even when they’re not suppose to be. I’ve heard about phantom loads for a while and was curious which appliances are affected and how much of a “phantom” load there really is. I’m lucky that my city utility office loans out “kill-a-watt” meters to measure 120 volt appliances and track their electric consumption over time, which is handy for things like refrigerators where compressor cycle on and off intermittently. Here’s my findings:
TV-DVD player and surround sound. 4 watts phantom
In use - TV 91 watts
In use - TV w/surround 149 watts
In use - TV/surround/DVD 152 watts
Microwave 4 watts phantom
Coffee pot 3 watts phantom
Clock/radio 7 watts phantom
Garage radio 3 watts phantom
55 gal fish tank 15 watts $9.43/yr
Cordless drill charger (14.4v) 6 watts phantom
Float charger 3 watts
Personal Computer 8 watts phantom
In use 140-160 Watt
Work Computer 20 watts phantom
In use 160 Watt
Includes printer/router/modem/and Vonage box $72.65/yr
Garage fridge 95 watts $59.77/yr.
Garage freezer 63 watts $40.05/yr
Kitchen refrigerator / freezer 157 watts $99.24/yr.
The stuff I’ve listed annual cost for are appliances I tracked over time (several days) and I’m sure there are a lot of variables that skew the data. For instance, the kitchen fridge was monitored when we had out of town guests for the week, so we had twice as many people opening and closing the door.
And we pay $0.07176 per kilowatt hour.
Also to note a couple things that didn’t have a phantom loads: toaster, phone charger (when not in use), and for some reason another digital clock radio. I don’t know why I couldn’t get a reading on the clock radio even trying several times.
Anyway it was interesting to see exactly how much electricity is being used by all the stuff plugged in all the time. We're constantly reminded of things like lights but it's good to be reminded about some of the less obvious things.
