Some data centers dwarf a football field and can cost more to build and power than the IT services they support. Today data centers consume about 2 percent of U.S. power generation. Now, everyone from the CFO to the Environmental Protection Agency (EPA) is interested in a data center’s footprint—economic and environmental. The GFS team is helping Microsoft and the industry find the intersection of cost and sustainability. Now, data center operators and architects are examining every phase of their power use. Microsoft is doing the same, squeezing efficiency from hardware and employing software that optimizes server performance. Today, Microsoft’s power consumption is between 30 and 50 percent lower than the global industry average for traditional data centers.
