As data centers expand to handle the exponential growth of global data traffic, the amount of energy they consume is increasing at an alarming rate. Currently, data centers use approximately 10 percent of the world’s electricity—predicted to grow to 20 percent by 2025—and in the process are also becoming one of the world’s biggest sources of pollution.
A major new $3.75 million study funded by the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) is designed to develop a solution to this problem. The three-year project, “FRESCO: FREquency Stabilized Coherent Optical Low-Energy WDM DC Interconnects,” is led by Daniel J. Blumenthal of the University of California, Santa Barbara (UCSB).
