Most monitors these days can be configured to sleep when the user is not using the keyboard/mouse, and the power consumption might go down from 120 watts (crt type) to 5 or 10 when in sleep mode.

NOTE!! By running those screen displays for ever, (which may be fun to watch for about 30 seconds :), the monitor never goes to sleep!!! The same person may think twice before giving the same $50 they waste to a charity :) :)
BTW, if you computer is in an airconditioned place, the cooling of this 50watts might take another 100 watts of energy.
