Five PC Power Myths Debunked
snydeq writes "Turning off PCs during periods of inactivity can save companies between $25 and $75 per PC per year, according to Energy Star, savings that can add up quickly for large organizations. Yet most organizations remain behind the times on PC power management, in large part due to common misperceptions about PC power, writes InfoWorld's Ted Samson, who outlines five PC power myths debunked in a recent report from Forrester, ranging from the energy savings of screen savers, to the energy draw of powering up, to the difficulties of issuing patches to systems in lower-power states."
Energy is kWh power is kW. "Energy at a rate" is power, and should be in kW not kWh.
One of our competitors trademarked the term "hypothesis". From now on, we will call them "boneheaded ideas".
"potential user complaints can be mitigated by communicating the positive financial and environmental benefits of PC power management."
Now that just plain hilarious.
Learn how to save $25 to $75 by purchasing the $279 dollar report that the article is hawking. No thanks. This article has no business even being on Slashdot. It isn't news, it is an advert.

You're making the assumption that people work continuously whenever their computer is on
I'm also assuming that you earn minimum wage. ;)
Moderating "-1, Disagree" is simple censorship. Have the guts to post your opinion.
I have never had a PC or a Laptop which was able to reliably "Suspend" or "UnSuspend" Never in my life.
Not with Windows or several Linux Distros. I would say at least 25% of the time the machine will not return and must be rebooted anyway.
From my experience with some corporations, the way it works is more like:
1. The left hand doesn't know, and doesn't want to know what the right is doing. If your department can save $10 bucks, but it costs everyone else 10 million in workarounds and lost productivity, who cares? You're the greatest anyway.
2. Any attempts to rein in waste and such effects, just introduces one more layer who'll get their bonus for making you buy a tool that costs $10 less, but where you spend 100,000 more in salaries to do the same job. Occasionally it introduces a masked form of corruption too: they get more bonus for buying a $1000 pencil at 50% discount, than a normal one at 5% discount. In the former case they "saved" $500 per pencil. They're that great.
3. Don't underestimate interdepartment power games. Making you curse and waste more effort for implementing my hare-brained cost-cutting schemes, is the gretest achievement some people can get. It's me having power over you. For some people it's a powerful drug.
4. Theatre. Being seen as doing something beats doing the right thing. You can see that at all levels and in all domains: security theatre, cost-saving theatre, etc. Being seen as being teh great green saviour can beat actually saving money.
5. In that vein, beware the new boss who just has to piss on everything to mark his new territory. The higher level, the more dangerous. These guys _have_ to show that they changed something. It shows vision, leadership, etc. So he'll cheerfully make an actual loss, just so he can put a good leadership and vision theatre.
6. There's a whole caste of people across the pyramid whose goal in life is to not rock the boat and not be responsible for anything. It's better to comply with a dumb rule (even one that wasn't supposed to apply to your situation or domain) than to have anything be your personal decision, and responsibility if it fails. Applying someone else's rule is like having a papal indulgence: whatever goes wrong, you're not the one who'll be punished for it. These fine guys and gals would mindlessly enforce even turning off the computers _during_ work hours, if that's what the rules say.
7. Don't underestimate the effect of rewarding failure. E.g., see the thing about "saving" money by buying a disproportionately _more_ expensive thing. E.g., in some places, keeping the people under you from doing their job can mean needing to hire more people, and if you get enough of them you get a promotion. E.g., being the guy who dumbly applies rules without thinking, cam actually get one a promotion or at the very least it's often enough to not get demoted or phased out.
So, yes, I've seen places where they paid consultants in the range of thousands per hour, but would rather pay those to twiddle their thumbs for a quarter of an hour while a baroque configuration starts, than "waste" cents on leaving that computer idle over night.

See, your math is nonsense. Not that it's wrong, its just that you CAN'T combine all those minutes to get something productive. The minute I save each day isn't going to make a difference to the next day.
That's why you use WoL to boot the system one hour before employees arrive, do a virus scan, check for updates, or other maintenance tasks.
1 hour is generally enough time for updates and virus scan. Employees come into a machine ready to go, you get regular maintenance and everybody's happy.
That step is only applicable if you are super rich. These days only billionaires get welfare.
