The Energy Efficiency and Renewable Energy Network (EREN) is part of the US
Dept of Energy. At the EREN website they list the wattage of many appliances.
http://www.eren.doe.gov/consumerinfo/refbriefs/ec7.html
The wattage of a CRT monitor is listed as 150 watts (awake) or 30 (asleep).
This means that in energy use, one hour of awake time = five hours of sleep
time for the EPA example monitor.
According to IBM, the T Series flat panel monitors consume 3-4 watts asleep and
30 – 65 watts awake.

Note that the awake energy use changes by a factor of more than 2, depending on
screen size. For a flat screen monitor which uses 3.5 watts (asleep) and 50
watts (awake) 1 hour of awake time = 14 hours of sleep time.
A LCD ususe about 1/3 the power of a CRT.....depending on size, and mfgr.

CRT uses more electricity because it is using a video tube which requires more electricity than LCD which uses liquid crystal.
