Green IT: An Emerging Challenge IT consumed about 61 billion kilowatt-hours in 2006—about 1.5 percent of the total electricity consumed in the US—at a cost of about $4.5 billion. Power consumption in the industry could nearly double by Report to Congress on Server and Data Center Energy Efficiency,” Environmental Protection Agency, Aug. 3, 2007 The price of building a new data center has quadrupled since 2000, in large part due to the costs associated with the infrastructure needed to power and cool the building.
