Green Grid Creates More Metrics For Energy Efficiency in Data Centers

The Green Grid consortium is developing two metrics to add to its power usage effectiveness metric for measuring energy efficiency in data centers. The new metrics will address carbon usage effectiveness (CUE) and water usage effectiveness (WUE). CUE will help officials determine how much greenhouse gas emissions come from the IT equipment in data centers, and WUE will help managers determine how much water is used by a facility for IT operations, according to the Green Grid.

Companies have been under pressure to improve the overall environmental profile of data centers following a report to the U.S. Congress, which calculated that data centers comprised 1.5 percent of all U.S. energy consumption, and that percentage could double next year. Data centers also use a significant amount of water to cool their equipment.

Meanwhile, cloud computing has been targeted as a source of global warming, and Europe has imposed carbon taxes for large energy consumers. The CUE and WUE metrics will be discussed at the Green Grid's Technical Forum next March.
