As part of the Obama Administration’s Better Buildings Challenge, the U.S. Department of Energy announced the first data center owners and operators who have committed to reduce their energy use by at least 20 percent over the next decade.

According to the DOE, data centers consumed about 100 billion kilowatt-hours (kWh) of electricity in the U.S last year, and that number is expected to grow as more information is shared and stored online.

“Through the Better Buildings Challenge, public and private sector partners are demonstrating leadership through their efforts to save money by saving energy,” says energy secretary Ernest Moniz. “As the Better Buildings Challenge expands, leading organizations are partnering with the Department to apply energy efficiency measures and energy management strategies that will shape the nation’s next-generation of data centers. In fact, if all data centers were 20 percent more efficient, the nation could save more than 20 billion kWh of electricity by 2020, which would result in roughly $2 billion in cost savings.”

The 19 new partners joining the Better Buildings Challenge include national laboratories; federal agencies including the Environmental Protection Agency, the Department of Defense, and the Social Security Administration; as well as companies including CoreSite Realty Corporation, ebay inc. and Staples. The new partners pledge to improve the efficiency of data centers, which altogether are currently consuming more than 90 megawatts of power, according to the DOE.
