Power consumption figures

[SIB]

I'm trying to work out how much power in consumed by PCs and peripherals at work but am unsure exactly how to work it out. What i need to know is how much power is consumed per hour by:

17" CRT in use and on standby
17" TFT in use and in standby
Bog standard PC (Dell GX280 P4 3ghz) in standby and under load
Laser and deskjet printer in idle

Any help much appreciated
