DRIVERS Direct
- regulations- stakeholder pressures- performance- financial
Integrated improvement- energy/environment one of many- supporting the business case- e.g. thin client- e.g. virtualisation

PRODUCTION BURDENS A typical semiconductor facility:
- 591 million gallons DI water- 5.2 million pounds of chemicals- 8.8 million kwh of electricity
PC/LCD production- 1,000+ hazardous substances
High energy materials- 2.5 tonnes of rock- for 1 gram of gold

GOVERNMENT CIO ADVICE - 1
Remove active screensavers Switch Monitor to Standby Shut down PCs OoH Active power management Re-use, re-cycle or green disposal Low power CPU & high efficiency PSU Thin client Timer switches for non networks devices Set default “green”print settings

DATA CENTRE PUE Power Usage Effectiveness
- ratio of total energy (ie servers + support) to server energy
1990s centres 2.0 + University of St Andrews 1.2 Cap Gemini, Swindon 1.08 Carbon PUEs below 1
![Page 16: ENERGY EFFICIENT IMPROVEMENT OPPORTUNITIES IN ICT - Evidence from the SusteIT Project Peter James University of Bradford.](https://reader031.fdocuments.in/reader031/viewer/2022032803/56649e395503460f94b2ab26/html5/thumbnails/16.jpg)
(MORE) EFFICIENT STORAGE OPTIONS
Manage- policies; deduplication
Optimise- tiered storage
Replace- more for less efficient devices
Extend- cloud, shared services
![Page 17: ENERGY EFFICIENT IMPROVEMENT OPPORTUNITIES IN ICT - Evidence from the SusteIT Project Peter James University of Bradford.](https://reader031.fdocuments.in/reader031/viewer/2022032803/56649e395503460f94b2ab26/html5/thumbnails/17.jpg)
HILLINGDON £26,500 power savings pa from: Storage management
- automated tiering- ‘thin provisioning’
Storage energy efficiency- less fibre channel- more SATA
Virtualisation- 94 production servers to 3

Free cooling Wall of 8 dry air coolers Flow temps vary Fans modulate up to 600prm
7C in winter = 100%FC 7-20C in Autumn 20C+ = no free cooling Discharge into plantroom past standby generator to
provide background heat in winter. Free cooling for over 80% of year.
