U.S. Environmental Protection Agency Issues Its Final Report on Server and Data Center Efficiency

The EPA issued its final report to Congress last week on Server and Data Center Energy Efficiency.

The EPA issues a final report to Congress last week showing that data centers in the United States have the potential to save up to $4 billion in annual electricity costs through more energy-efficient equipment and operations and the broad implementation of best management practices.

The "Report to Congress on Server and Data Center Energy Efficiency"

Findings from the report include:

  • Data centers consumed about 60 billion kilowatt-hours (kWh) in 2006, roughly 1.5% of total U.S. electricity consumption.

  • The energy consumption of servers and data centers has doubled in the past five years and is expected to almost double again in the next five years to more than 100 billion kWh, costing about $7.4 billion annually.

  • Federal servers and data centers alone account for approximately 6 billion kWh (10 percent) of this electricity use, at a total electricity cost of about $450 million per year.

  • Existing technologies and strategies could reduce typical server energy use by an estimated 25%, with even greater energy savings possible with advanced technologies.

As the U.S. economy increasingly shifts from paper-based to digital information management, data centers have become a vital part of business, communication, academic, and governmental systems. Over the last five years the increase in use of these systems, and the power and cooling infrastructure that supports them, have doubled energy use, increased greenhouse gas emissions and raised concerns about power grid reliability.

In December 2006, Congress requested that EPA develop the report to examine market trends in the growth and energy use of servers and data centers. The report complements EPA's ongoing efforts to develop new energy efficient specifications for data center equipment as well as explorations into a new Energy Star building benchmark for data centers that reflects whole building operations.
