About Electronics

Over the last twenty five years, the number of consumer electronic devices in the average American household has increased substantially.  With each new year, more innovations hit the marketplace.  PC's, DVD players, satellite receivers have all found they way into our homes in the last 15 years. 

These devices, which are designed to increase your productivity or provide entertainment, consume electricity whenever they are turned on.  As would be a surprise to many people, these devices also consume power when they are turned off.  When power is consumed by a device that is turned off, this consumption is known as a "phantom load"

As shown below, TV's, cable boxes, and satellite receivers have significant phantom loads.  Over a year's time, the costs of keeping these items plugged in but turned off becomes substantial. 

Annual cost @ $/kilowatt-hour
Turned On Watts Turned Off Watts Kilowatt- Hours/Yr $0.04 $0.06 $0.08 $0.10 $0.12
32" Color TV 134 17 149 $6 $9 $12 $15 $18
PC Pentium 4 Processor 82 5 43 $2 $3 $3 $4 $5
17" Monitor 55 12 107 $4 $6 $9 $11 $13
All-in-One Printer 28 7 64 $3 $4 $5 $6 $8
Mini-Dish Satellite Receiver 16 16 139 $6 $8 $11 $14 $17
VCR 15 4 32 $1 $2 $3 $3 $4
DVD Player 13 12 107 $4 $6 $9 $11 $13
Cable modem 10 10 85 $3 $5 $7 $9 $10
Total 352 83 725 $29 $43 $58 $72 $87

For example, if you own a 32" color television is plugged into an outlet but is not turned on for an entire year, it will still consume 149 kilowatt-hours per year.  If your electric utility charges you $0.08 per kilowatt-hour, that "turned-off" set will have cost an extra $12 on your power bill.
