I honestly don't know a single person or a business who shuts down computers for 16 hours/day consistently. Not a single one. Power consumption should be measured as 8-10 hours at 50% load, and 14-16 hours at idle. That easily doubles your estimates, I think. Not to mention the places where power is more expensive than $0.12/KWh
