Check out these links one is a research study we conducted on the subject and the other is a paper we wrote for WYSE, they cover pretty much exactly what you asked for. Some of the newer PC/TC equipment is actually going to consume more than shown here, while the LCD may now consume less. The energy cost equations can easily be adjusted for your actual kilowatt per hour cost from your local utility... http://www.thinclient.net/comparingpowerusage.html http://www.wyse.com/resources/whitepapers/energy_study.pdf Steve Greenberg Thin Client Computing 34522 N.

Things I need to calculate. Existing power used by PC and CRT monitor versus a thin client with LCD screen. Need to take into account heat output power consumption etc. Anyone got anything they have either done themself or seen online. Send offlist if required. Thanks in advance
