I got a new device (kill-a-watt) that measures watts/amps/volts and decided to measure the watt usage of lots of devices I had access to through friends and family. Here are my findings:

All numbers below are in watts

Microwave: Idle - 2, Door Open - 35, Surface light - 74, Fan on high - 126, Fan on low - 100, Regular heating - 1635.

Torche Lamp w/100w bulb & dimmer switch: Low dimmer - 67, High dimmer - 98.

19" Viewsonic monitor: On - 121.

Dell 15": Orange power save light on - 1, Powersave menu on screen - 63, on - 67.

Motorola HD cable box: Plugged in turned off - 23, Powered on - 24.

DVD player: Plugged in turned off - < 1, Powered on - 10.

Larger Stereo Reciever: Plugged in turned off - < 1, Powered on - 53.

Smaller Stereo Reciever: Plugged in turned off - < 1, Powered on - 28.

65" TV: Plugged in turned off - 5, Powered on - 192.

15 year old 20" TV: Plugged in turned off - 11, Powered on - 75.

Ipod charger: Plugged in charging - < 1

8 port switch : Plugged in - 6

Cable modem:Plugged in - 5
