  • “Zombie” Servers and Inefficiency Drive Energy Waste at Data Centers

    The high energy demand of those servers is well documented, but up to 30 percent of them are drawing power without actually doing anything.

    These “zombie,” or comatose, servers are among the examples of energy waste documented in a report about U.S. data centers released Tuesday by the Natural Resources Defense Council (NRDC). If those facilities were to cut electricity consumption by 40 percent—half of what is possible using the tools now available to improve efficiency—the electricity savings would amount to $3.8 billion and 39 billion kilowatt-hours, according to the report.

    (...) Large companies such as Google, Facebook, eBay, and Microsoft are already highly efficient, a result of major resources and huge scale, but their share of electricity use is just 5 percent of total data center consumption in the United States.

    “Our concern is more about the other 95 percent”
