IT is not green… 35% 65% Fossil Fuel Electricity Generated Heat Exhausted 2.5 % 95% % Data Centre Transmission Losses Transformer Losses Data Centre 40% 25%35% Data Centre Equipment Cooling Losses Power Infrastructure IT Equipment 65% 20% 15% Servers Network Equipment Storage Equipment Servers 30% 45%25% CPU Power Supply Other Components CPU 20% 80% CPU Utilisation Idle Time Power CPU Load Power 0.5% of Fossil Fuel Energy 100% of Fossil Fuel Energy BCS Data Centre Specialist Group

The University of Leeds World-class, multi-discipline, research- intensive university £500m pa turnover 32,000 students 8,000 staff Countless regional, national and international collaborators and information users
4
IT at the University £35m pa on IT – 7% of turnover 12,000+ university computer clients 500+ servers 10,000? student personal computers on campus and in residences High Performance Computers (HPC) Two enterprise data centres (third being developed), seven medium data centres, numerous informal servers IT and air conditioning two greatest energy growth areas at the University
5
Sustainable development at Leeds Cost reduction, legislation, institutional desire and individual goodwill University strategic objective Deputy Vice-Chancellor led Sustainable Development Manager Six strands: Estates Finance & Procurement Academic & Educational Alignment Citizens IT (“SusIT”)
6
IT sustainability areas Purchase/disposal carbon impact Materials, production, packaging, transport, disposal Recurrent carbon impact Energy consumption and usage efficiency Capital cost Purchasing and tender requirements Recurrent operating costs Licences, maintenance, support, etc.
7
Reducing the carbon footprint of IT and using IT to reduce our carbon footprint Leadership and education Stop it getting worse: Procurement policy Manage what we currently have: Measurement The largest energy consumers: data centres The largest number of energy consumers: clients (12,000+) and printers (30m pages pa) Make it better in future Data centre design and IT architecture Server-based computing Remote and mobile working
8
First successes IT procurement policy changed Institutional PC procurement Whole life-costing of new HPC Blank (with passwords) screen savers Automated power down of monitors and clients 4,300 PC trial: 0.7GWh and £73k pa saved Server virtualisation Printers and print management Students first: pull, multi-functional devices, £90k pa expected savings

The size of the issue 2% of global C0 2 emissions down to IT – equivalent to the airline industry (Gartner) IT predicted to triple its emissions between 2002 and 2020 (The Climate Group) An enterprise class data centre uses more power in one year than the city of Leicester (Broad Group Research) Energy costs predicted to rise from typically less than 10% of the IT budget to more than 50% in the next few years (Gartner) Two-thirds of office energy consumption is down to IT (The Carbon Trust)
