Update:
Just found that our facilities people did an in-depth analysis on this over a year ago. The findings show that enterprise wide we'd be saving over $100K/year. It was never implemented. No idea why yet. Right now we are in cost savings mode, which I'm sure most other organizations are as well. I'm thinking this will be looked at more closely now, and hopefully implemented.

The company tested sample computers using a Kill-A-Watt type device. I don't have the exact figures but the admin type desktops saw very little savings in turning them off. The engineering pcs saw bigger savings but they, generally, were doing things at night so they couldn't be shut off anyway. In the end, it was decided not to change the policy of keeping all pcs on 24x7. One issue that was raised, but not looked into, was what affect increased power cycles would have on hard drive life. Something to think about. Phil On Thu, Feb 4, 2010 at 4:51 PM, Christopher Bodnar <[email protected]> wrote: Anyone actually go through this in the real world and see a significant savings?

A quick Google came up with an average of 10-15 Watts used for standby mode. We were just talking about this here last week, in regards to all of the electronics in our homes that now run in standby mode.

Average 65 watts for 1 computer (while idle) 8760 hours in a year - 2000 (hours you are at work) = 6760 (hours you are not at work per year) 65 watts * 6760 hours / 1000 = 439.4 kilowatt-hours 439.4 * $.119 (RATE) = $52.29 (cost per year of one computer being on while you are not there) -----Original Message----- From: Kurt Buff [mailto:[email protected]] Sent: Thursday, February 04, 2010 3:04 PM To: NT System Admin Issues Subject: Re: OT: WOL cost savings On Thu, Feb 4, 2010 at 10:45, Christopher Bodnar <[email protected]> wrote: > Has anyone put something together to show management in regards to the > possible ROI of using WOL?

I've seen some general > stuff out there that range between $25-$75/year per PC. But not how that was calculated. One obvious metric is to calculate energy costs for the PCs - how much electricity they consume when turned on 24x7 vs when turned on 8x5. That alone should be fairly significant.
