Optical Interconnects & Data Center Efficiency Workshop

ARPA-E held a workshop on Optical Interconnects & Data Center Efficiency on July 27-28, 2015 in Burlingame, CA. This workshop convened leading experts in data centers, high performance computing, optical interconnects, data center efficiency, power systems and other relevant areas to identify innovative research paths forward for the development of disruptive technologies that can significantly reduce the electricity consumption of data centers and improve data center efficiency.  

In 2013, U.S. data centers consumed an estimated 91 billion kilowatt-hours of electricity, or about 1.9% of the total U.S. electricity consumption. The data center consumption is projected to grow to about 3% of the total U.S. electricity consumption by 2020.

Areas of interest and primary objectives of the workshop included:

  • Identification of key technical areas for ARPA-E investment to reduce current and projected data center energy use
  • Establishing research program concepts and critical milestones that will help formulate a future ARPAE-E investment
