Thanks to better cooling and powering strategies, better power management and cloud computing, the energy consumed by data centers is under control, according to a new report from the Department of Energy’s Lawrence Berkeley National Laboratory.
After rising rapidly for more than a decade, energy consumption by U.S. data centers started to plateau in 2010. Since then it has held steady, accounting for just under 2 percent of total U.S. energy consumption, the report finds. The growth rate for energy consumption is expected to remain now, even though the total server installed base is projected to increase by 40 percent from 2010 to 2020.
