Report: Improvements at U.S. Data Centers Could Save $3 Billion Yearly

Improved energy-efficiency practices for U.S. data centers could cut energy waste by at least 40%, saving more than $3 billion annually, according to a report released on August 26 by the Natural Resources Defense Council (NRDC).

The report, “Scaling Up Energy Efficiency Across the Data Center Industry: Evaluating Key Drivers and Barriers,” notes that while huge “cloud” server farms have made significant efficiency improvements, progress has been much slower and uneven across the nearly 3 million other data centers in businesses and organizations that house 95% of servers across the United States. The report estimates that this waste costs billions of dollars and kilowatt-hours yearly. For example, up to one-third of servers are no longer needed, but are still consuming large amounts of electricity, while many others are grossly underutilized and operating at no more than 18% of capacity.
