[K12OSN] OT: cost of operating one pc per year

[Doug Simpson]

Yeah, If I figured it right (and I may have missed it by some) it could save $100,000 per year. . .

That was figured with a computer drawing 150 watts and a monitor connected to it drawing 100 watts and there being 975 in the district all left on 24/7.
That would cost $204,000 per year for the electricity. Divide that by 3 (8 hours opposed to 24) and you get 68,000 and then multi that by two for the 12 hours they are off, and that leave $136,000. saved. Likely it would be a bit less but still a chunk of change! And in reality, all computers aren't on 24/7. Some are energy conscience enough to turn theirs off, but it was a *what if* kind of scenario. 

And that was figured at 7 cents per KWH. 

Scary, huh?

Doug,

Thanks for the info / numbers,, WOW 100K!!! that's nothing to sneeze at
regardless of school district size. BTW: Did you do any crunching as far
as oldie monitor's versus lcd's by chance? We have ( most ) of the boxes
set to up at 8 am, shut off at 4 pm. I know of a couple districts close
to here that leave pc's on 24/7 during the school year, I think i'll
make a deal with their supers to drive there and shut pc.s off each
night  if i get 50 % of the savings:)hhmmm...50k x 2 = ???...wwhoohooo!
Thanks again----
