Summit on Energy Efficiency May 1-2, 2013 - Register today! 
Steven Chu This year's UC Santa Barbara Summit on Energy Efficiency will be held on May 1-2, 2013 at the Fess Parker Resort in Santa Barbara. The Summit will focus on Materials for a Sustainable Energy Future.  In addition to our opening keynote speaker -- Dr. Steven Chu, U.S. Secretary of Energy -- we have many other experts gathered to discuss the latest science and technology innovations that are driving energy efficiency. A list of speakers and session details can be found on our Summit website. The early-bird registration discount has been extended to April 5th - register today!
ICT Technology Roundtable        
On February 7-8th, 2013, the Institute for Energy Efficiency hosted a Technology Roundtable on Information and Communications Technologies Core Networks. This 
high-level event brought together 27 leading stakeholders from the private sector, government, and academia. Through highly interactive discussions, participants identified technological and architectural advancements needed in transmission, switching, and routing to develop scalable, energy-efficient, next-generation core networks. A report is currently being prepared highlighting roundtable findings
The lead sponsor for this Technology Roundtable was Juniper Networks, and supporting sponsors were Ciena, Sprint, and the U.S. Department of Energy's Energy Sciences Network. Read more about the roundtable here.

 Faculty News & Research

Institute is awarded $1.6 Million from DOE's ARPA-E

The Department of Energy's ARPA-E awarded the Institute $1.6 million to develop an energy storage device for hybrid electric vehicles led by Professor Galen Stucky's research group. The technology combines the properties of batteries and capacitors into one technology.

According to ARPA-E the device "could charge within minutes, deliver more power, and have a longer life expectancy compared to today's electric vehicle batteries." Click here to read the full news release.


Eliminating network congestion in data centers 

Institute faculty member Dr. Heather Zheng and her colleagues in the Computer Science department have been working on innovative solutions to the issue of network congestion in data centers. This congestion often occurs during sudden bursts of activity and can cause major 

bottlenecks in the transfer of data, which translates into service downtimes. 
Their solutions involve bouncing wireless 60GHz beams off polished metallic plates on the ceiling, reducing interference and taking advantage of the multi-gigabit bandwidth that the 60GHz radios provide. Their most recent experiments have verified the properties using real hardware. Now these wireless links can augment existing wired connections in data centers, alleviating the congestion in a matter of milliseconds.

Dr. Zheng's research has received significant press coverage over the last year: New York Times (01/12)MIT Techology Review (04/12)ComputerWorld (05/12)Read the full text paper here

UC Santa Barbara Students Win National Sustainability Contest at White House 
An interdisciplinary team of UC Santa Barbara undergraduate, graduate, and doctoral students have taken a top prize at the 2013 Better Building Case Competition. This competition is part of President Obama's Better Buildings Initiative, which is striving for a 20 percent reduction in commercial and industrial energy use by 2020. Several Institute faculty and graduate students were involved with this team. Read the full news release here.
