Benchmarks "Earlier this week Apple released updated Mac Pros that use Intel's new Penryn processors. Also new is the fact that the standard Mac Pro configuration now comes with eight (instead of four) cores. Of course, what I've been wondering (as I sit here and think about getting a new Mac Pro) is how does the new standard eight-core Mac Pro perform compared to the old high-end Mac Pro? I've gathered Geekbench 2 results for both Mac Pros to find out."

Sleep mode is nowhere near 10W. Your average laptop battery is only about 55W-HR, and a laptop will easily last a day or two in sleep-mode with a full-charge. That puts the sleep-mode power draw at 1-2W.

To put that into perspective, a single gallon of gasoline has about 36,600W-HR of energy, enough to power a laptop in sleep mode for two to four years.

To put it still further into perspective, powering all the laptops sold worldwide in a year in sleep mode for a year will use about 25 million gallons of gasoline. This sounds like a lot, but the US alone uses that much gasoline in only 90 minutes...

The power savings from shutting down computers is so phenomenally miniscule it's barely worth even posting about.
