+1 for the Kill-A-Watt. Works great! ________________________________

I was relaying the experience of one company I know that looked into the issue; I wasn't advocating whether or not someone should shut down their computers at night. I would suggest, though, that anyone looking in to this do their own testing rather than depend on online calculators that may not reflect their actual equipment. For example, the site you link to pegs a pc at 84 watts at idle but the energy star web site linked to earlier says that a "value" pc uses only 37 watts while idling. Quite a difference between the two. Rather than guess which one is closer to your equipment spend the $20 bucks for the Kill-A-Watt device and test your actual usage. (No, I do not work for, or have any interest in, the company that makes the Kill-A-Watt. :-) On Thu, Feb 4, 2010 at 5:49 PM, Rod Trent <[email protected]> wrote: Did you check out the calculator already? http://www.1e.com/energycampaign/Calculation.aspx From: Philip Brothwell [mailto:[email protected]] Sent: Thursday, February 04, 2010 5:46 PM To: NT System Admin Issues Subject: Re: OT: WOL cost savings I know one company that looked into it a year or so ago. 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?

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.
