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.
