Report to Congress on Server and Data Center Energy Efficiency: Public Law 109-431


This report was prepared in response to the request from Congress stated in Public Law 109-431 (H.R. 5646), "An Act to Study and Promote the Use of Energy Efficient Computer Servers in the United States." This report assesses current trends in energy use and energy costs of data centers and servers in the U.S. (especially Federal government facilities) and outlines existing and emerging opportunities for improved energy efficiency. It also makes recommendations for pursuing these energy-efficiency opportunities broadly across the country through the use of information and incentive-based programs.
