Integrated improvement- energy/environment one of many- supporting the business case- e.g. thin client- e.g. virtualisation

THE DARK FOOTPRINT OF THE KNOWLEDGE ECONOMY

Heavy Burdens

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

THE DARK FOOTPRINT OF THE KNOWLEDGE ECONOMY

Heavy Burdens and …. Steam Computers

SUSTEIT HE FINDINGS Sheffield

- £1 million + electricity bill- 47% desktop related

HE sector wide- 760,000 PCs- 215,000 servers- 147,000 networked printers- £60 million + energy bill- 35/40% data centres/HPC

NHS ICT Carbon footprint England

- 18 million tonnes (25% public sector)- Procurement (Embedded) 60%- Building Energy 22%- Travel 18%

ICT- 15% Building energy?- 5% Embedded energy?

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

GOVERNMENT CIO ADVICE -2

DATA CENTRE OPPORTUNITIES 2010

- Adapted from EPA Original

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

(MORE) EFFICIENT STORAGE OPTIONS

Manage- policies; deduplication

Optimise- tiered storage

Replace- more for less efficient devices

Extend- cloud, shared services

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

ICT BENEFITS – SMART 2020

Benefits- 15% cut in CO2 emissions by 2020- $946 billion of cost savings- 5:1 CO2 avoidance/creation ratio

Means- smart grid- intelligent buildings- new ways of working

Hot & Cold Aisles

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.
