The net rate in my case is $.18 per kwh. But with all taxes, base fees, investment charge for green energy it adds up to $.25 per kwh. This is the average for a yearly usage of 7100 kwh. So it is almost the same as you pay. Your $15/mo/computer equals to app 270 watts (8 hrs per day at $ .23) which is not a portable but a desktop PC with all peripherals attached. Its app the same I have with my setup. In my setup I use a 10-outlet with surge protection and a master/slave function. When the PC connected as a master is shut down then all other outlets (slaves, with the screen, printers, external disks etc) are also automatically shut down. Every evening I put the PC in hibernation mode. This shuts down the PC and with the master/slave setup all connected I/O's and has an acceptable start up time. Hibernation has the advantage above the STANDBY mode that the PC is really shut off and you don't loose the data in memory in case of a short power drop.

How does that compare with yours?

But I don't know your electric rates, what is it per Kilowatt-Hour (kWhr). The ongoing heat might depending on the design degrade the plastic parts. It is actually the inrush current that kills the most electronic parts during power on. The bearings of the hard drives shouldn't represent a problem it is a more likely problem that the read/write heads stick to the disk during power off which get damaged during power on. I have 5 desktop PC's running at my friends company for over 11 years 24/7/365 without any problems. I bet you, that if they would have switched them of every day they all would have gone broke for one or the other reason mostly for electronic failure due to the inrush current.

Or is the most wear due to the surge of power when you turn it on and the stress on the bearings on the hard drive? I turn off my computers at night (actually go to standby so they start faster). I once figured it saved about $15/mo/computer to turn them off a night but San Diego has pretty high electric rates.

It's using the power supply, of course, not the battery. Is there a down side to this? will the machine wear out more quickly because of this? Even though it's a notebook, I rarely move it, so I just leave it running.
