Both Google and Microsoft in the past month have disclosed details of their data center energy usage, confirming that the two software giants operate some of the most efficient facilities in the world.On Oct. 1, Google said it is averaging a Power Usage Effectiveness (PUE) rating of 1.21 across its six data centers, while Microsoft said this week its testing shows that the 40-foot shipping containers packed with servers the company is installing in its new Chicago data center can deliver a PUE energy efficiency rating of 1.22, which may actually exceed the PUEs reported by Google since Microsoft includes house lighting and office loads in its PUE calculation. "They are required to run the facility, so we count them as overhead," Microsoft's Mike Manos said.
