Data centers are some of the most energy intensive buildings in California, using 1.46 terawatt hours per year. Ecos Consulting, in coordination with Lawrence Berkeley National Laboratories and EPRI, and with support from the California Energy Commission, has demonstrated an alternative that could cut that use by 20%. Ecos Consulting is working to cut AC-DC-AC conversion waste with a new distribution architecture that will deliver DC power directly to servers. With 10% adoption, this alternative delivery system would save 29.2 GWh annually and prevent the emission of 23.5 million pounds of CO2. The project was accomplished through coordination and support by a host of private companies such as HP, Sun, Cisco and Intel.
