If it is used continuosly how much electricity per hour is the consumption? What about in screen saver mode?

Sorry! Got confused with units, this is the real answer!
Computer 350 ~ 500W,
17" TFT screen about 25W an hour. A CRT of the same size will probably be around 50W, though I am not too sure on that.
With the computer though the power consumption is based on the load, i.e how much hardware is inside and (To a lesser extent) how mcuh work the machine is doing. 300W should be a resonable number to use.

The computer is not really using so much energy to be of major concern, even if you left it on.
On a very non-technical level, the energy used is not more than a conventional halogen lamp of 300W.
modern LCD monitors use way less energy than their CRT counterparts, so there's more savings there. As anothr poster said, screen saver mode does nothing except exercise the CPU, since LCDs do not need to have a screen saver ( screensavers were meant for CRTs, to avoid burning the CRT inner surface coating )
and if you really want to minimize your power usage, adjust the computer hibernation settings for your personal usage pattern.

It depends on the PC, however, here are some examples:
According to tests conducted by IST, Hardware Support, tests showed the following. On a Pentium 4, 1.7GH machine:
- during boot power in watts is close to 110w
- during idle, no power management,. close to 60w
- during full power saving, no hard disk spin, machine in sleep mode, 35w
The total power consumption of a typical PC and monitor does not consume more than 175 Watts of energy at its highest rate. At night time when your PC is "sleeping" it only consumes 35 Watts.

answer 1 is correct ... and screensaver mode actually uses high power because its processing video .... its a screensaver not a powersaver ... putting the pc in hibernate or standby is powersaving ...
