Information technology is so pervasive that estimates of its power usage show that data centers, locations where computing systems are densely packed consume some 2% of available power in mature economies. Other estimates show that an additional 8% or so of power is consumed by IT systems which reside in offices and homes, while assessments of power used consumer devices such as mobile phones and PDA’s combined with other household appliances while charging or not deployed can add another 6-8% of total power consumption. As computing power densities have increased from a few tens of watts per square foot to hundreds of watts per square foot considerable attention has been applied to the management of power in IT systems.
