ENERGY EFFICIENT DATA CENTRES
– AN OVERVIEW
Professor Peter James
BACKGROUND
• Higher Education Environmental Performance Improvement- Green Gown Awards - www.heepi.org.uk
• Sustainable IT in Tertiary Education- Strategic review of IT in universities- Identifying & disseminating good practice- www.susteit.org.uk

ELECTRICITY CONSUMPTION
• High power consumption- ICT 10% UK electricity- Data centres 1.5% (8GW)- 46 TWH 2006 to 93 2020= aviation/refrigeration
• High summer load- system reliability
WHY IT MATTERS TO HE
• Cost- 50 to 100% rise in electricity prices?
• Carbon- growing regulation- Carbon Reduction Commitment
• Capacity
