DESCRIPTION:Energy and sustainability have become one of the most critical
  issues facing our society. This talk presents my research efforts in maki
 ng IT systems more sustainable\, and furthermore\, using IT to improve the
  sustainability of the energy system.\n\nIT represents the fastest growing
  sectors in energy usage and greenhouse gas pollution. Over the last decad
 e there are dramatic energy efficiency improvements\, but these do not nec
 essarily lead to sustainability because more servers are demanded and dirt
 ier energy sources are used. In the first part of my talk\, I will use Geo
 graphical Load Balancing as an example to illustrate how to exploit the sp
 atial flexibility in cloud workloads for renewable energy integration. In 
 particular\, I design algorithms with theoretically provable guarantees to
  deal with information uncertainties and the need of distributed control. 
 Moving from theory to practice\, I helped HP design and implement the indu
 stry's first Net-Zero Energy Data Center. \n\nMaking IT sustainable is the
  first step. My broader view is that the cloud can\, and should\, play a s
 ignificant role in improving the sustainability and efficiency of the broa
 d energy infrastructure. The second part of the talk focuses on data cente
 r demand response as an example. I will discuss its great potential and ch
 allenges\, as well as my recent efforts in both control algorithm design f
 or customers and market design for utility companies and our society. Some
  of the work is under industrial transfer with HP and utility companies.
