Data Centre Power Consumption Lower than Anticipated Reveals Report

The World’s data centres are using less electricity now than it was earlier predicted, thanks to economic slowdown and innovative power saving technology.

According to a report compiled by Stanford University consultant Jonathan G. Koomey, the amount of electricity consumed by data centres globally increased by 56 percent between 2005 and 2010, while in the United States, data centre electricity increased by only 36 percent.

The report, titled “Growth in Data Centre Power Use 2005 to 2010”, was commissioned by The New York Times.

The number of data centres actually declined compared to the forecasts made in 2010, due to the financial crisis in 2008 and the rise of power saving technologies in the form of more efficient computer chips and server virtualisation.

“The 2008 financial crisis, the associated economic slowdown, and further improvements in virtualisation led to a significant reduction in actual server installed base by 2010 compared to the IDC installed base forecast published in 2007,” Koomey wrote in the report.

“Considering the latest installed base estimates for 2010, the growth in volume servers slowed considerably in the 2005 to 2010 period, growing only about 20 percent in the U.S. and about one-third in the world,” the report read.
