Green Internet Symposium

To draw together interested members of industry, academia and the general
public CUBIN (together with ISSNIP support) hosted The Symposium on
Sustainability of the Internet and ICT at the University of Melbourne. The
Symposium was the first Australian research conference on the issue of
sustainability and ICT. As such, it provided participants with an opportunity to
hear the latest research and industry developments in this fast moving field.
Approximately half of the participants were academic and half industry
representatives. The program included an opportunity for audience participation
in each session to debate the ideas presented by the speakers.
A range of critical issues were discussed, including:
• Energy demands of future ICT & Internet equipment
• Sustainable architectures and protocols for the future
• The impact of ICT/Internet growth in developing nations
• Regulation and the sustainability of the Internet
• Growth of Internet services and sustainability
The Symposium attracted 71 participants including 23 speakers with a high
proportion from industry, indicating the commercial importance and relevance of
the topic. The Symposium attracted local, national and international media
attention, including several radio interviews with local researchers.
The Symposium speakers were:
• Jayant Baliga, University of Melbourne
• Sean Casey, Intel
• Kevin Chen, Google
• Ric Clarke, Alcatel-Lucent
• Robin Eckermann, Canberra University
• Eng-Lim Goh, Silicon Graphics Inc.
• Turlough Guerin, Telstra
• Saman Halgamuge, University of Melbourne
• Steve Hodgkinson, Ovum Consultants
• Sundeep Khisty, EDS
• Lachlan Kidd, Cisco
• Angus MacDonald, Sun Australia
• Tony Morton, Econnect
• Luis Neves, Global e-Sustainability Initiative
• Jodi Newcombe, The Climate Group
• Max Ott, National ICT Australia
• Alison O'Flynn, Fujistu Consulting
Two keynote speakers, Dr. Bill St.Arnaud from Canada and Dr. Luis Neves from
Germany, addressed the Symposium from overseas, via video connections.

Dr. St Arnaud pointed out that the impact of global warming was exceeding the
worst case prediction of climate models. ITC has the potential to reduce energy
usage in other industries by 15 % through virtualisation and de-materialisation
(of books, music, videos and other products). However, several speakers
mentioned the difficult of reducing carbon footprint by increasing the energy
efficiency of equipment and processes. The Khazzoom-Brookes postulate states
that greater energy efficiency reduces cost and therefore promotes increased
usage. Many speakers provided suggestions for lowering the energy usage of
data centres through the use of virtual servers, load scheduling and simply
switching off servers at times of low load. Ideally, we should move to a “zero
carbon” ICT industry since the benefits of increased ICT usage then come at
“zero” cost.
