[QUOTE="MacInWin, post: 1802577, member: 396914"] I did some quick math. The MBP now has an 85w power brick, although in most modes it draws much, much less than that. But assuming 85 w continuously used, in a year that is 744KwH. In my home state of Virginia, the average cost of a KWH of electricity is 12.33 cents, which means that at max usage, a Mac will draw no more than $91.81 per year, or about $7.65 per month. If the average usage is, as I suspect, about 33% of the power brick max, then the figure is closer to $30 a year and about $2.40 per month.(I got the 33% through Coconut battery, which showed a power usage of 28 watts just now.) Bottom line, the MBP doesn't take much power to keep on 24/7. And the delta between being on, say 12 hours and 24 hours is even smaller. [/QUOTE]
