Compared to idle-mode, for a 500 MHz P-III you can expect about 5 W more with prime95. A 1 GHz P-III should draw about 22 additional watt.

So if you borg a typical office system running 8/5, the figures add up to:

P-III 500: About 8KWh extra/year --> 0.8$
P-III 1000: About 45 KWh extra / year --> 4.5$

If you run a P-IV 3060 24/7 you get about 525KWh extra --> about 50$/year extra.
So let me see here... 22 watts per hour x 8 hours per day = 176 watts x 180 days = 31680 watts per year / 1000 = 31.68 KWh x 0.0705 cents per KWh (current electricity cost) = $2.23 (approx) per computer x 60 computers (again, approx) = $134 per year.

Thanks for all the replies, this'll be very helpful.
