EPA increases data center efficiency resources
As digital computing has grown so has energy use by data centers, spurring EPA to announce plans to expand resources and efforts related to the energy efficiency of U.S. data centers. EPA has:
- Updated ENERGY STAR® certification specifications for data storage products,
- Improved the data center website and increased the resources offered at the site, and
- Kicked off updates to the ENERGY STAR® scoring system for data centers.
Many of the recommendations provided by EPA can be used by data centers of all sizes, independent of the ENERGY STAR® certification. Facilities can:
- Replace standard fans with variable speed fans to achieve cooling at the same time as energy reduction.
- Evaluate the potential to raise the data center temperature slightly; according to EPA, some equipment can handle slightly higher temperatures and can result in a savings of four to five percent of energy costs.
- Consolidate servers or move to “virtual servers” to reduce the numbers of servers in use.
- Look at data center layout modifications to optimize air flow, form hot and cold aisles, or add hot air barriers such as curtains.
Whether operating an embedded data center (i.e., smaller spaces and loads, including server closets and rooms) or a larger data center facility, energy reduction is a priority. One CEO, whose company operates data centers ranging from server closets at industrial plants to dedicated blockchain data centers, reinforced this point by sharing, “Energy is the primary raw material so reducing its use makes a big difference.”
