Green ICT in Further and Higher Education: The UK

Experience

Structure- Background- Greening OF ICT- Greening BY ICT- Greening ICT Curricula- Drivers- Conclusions

ABOUT THIS Sustainable ICT?

- environmental, social & economic- uses of ICT (e.g. privacy, repression)

Green ICT?- environmental, narrow social

Low Carbon ICT? Energy Efficient ICT?

Provider of digital infrastructure and services to UK education, as SURF- high capacity network & related activities-JANET (ja.net)- guidance and advices- ICT-enabled libraries/learning

Research/Action Programmes- SusteIT 2008- Green IT c £3 million

ABOUT

Environmental Improvement- improvement ‘clubs’ with technical inputs- www.eauc.org.uk

Responsible Energy Costs- e.g. devolved energy budgeting, whole life costing

Behavioural/Technical- Sustainable ICT use e.g. desktop powerdown, file storage, HPC, printing, server rooms- Dematerialisation e.g. e-readers, videoconferences- Cloud computing and thin client- Flexible working- Reporting sustainability-related information

PROJECTS

1998 – world’s first NGO for Green ICT- research, guidance, policy

EU Involvement- Sustainable ICT consultation for Lisbon- Sustainable Teleworking (Sustel) project- Expert Groups eg ICT & Energy Efficiency

ABOUT

GREENING OF ICT

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

DATA CENTRE OPPORTUNITIES

2020 AGENDAS

Device proliferation Increasing

functionality Increasing

accessibility New applications ‘Exabyte research’

2020 AGENDAS Technology/material transitions Energy aware software Net zero carbon

- data centres- networks- supply chains

System integration- grid related location

Local integration Greening the cloud

GREENING BY ICT

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

GREENING ICT CURRICULA New degrees

- MSc in Green IT New modules Projects

- university IT footprinting- repairing old equipment

Absences- change management- software coding

10 - EXHORTATION Greening Government IT

- Central Government's office estate Carbon Neutral by 2012- Carbon neutral across the ICT life cycle by 2020

“Countries from around the world are now looking to us for advice on how to follow our lead"

9 – IT SUSTAINABILITY CONCERN

Task focus Performance worries Narrow definitions Lack of financial responsibility Complex supply chains in

many countries

8 – CARBON“EU carbon prices could remain languishing at little more than €20 a tonne up to 2020, based on the current EU emissions target and without further restriction of UN carbon offset credits” – Societe Generale

CONCLUSIONS

Small inputs can produce large output Multi-stakeholder partnerships are the future There is no green IT community The biggest gains may not be environmentally

driven

CONCLUSIONS

There is enormous opportunity Central support is crucial

- information and understanding- creating networks- practical assistance- overcoming capital/revenue disconnects

(MORE) EFFICIENT STORAGE OPTIONS

Manage- policies; deduplication

Optimise- from monolithic SAS/SCSI- to nearline SAS/SSD mix- 150TB 15 to 2.5kW

Replace- higher efficiency devices

Extend- cloud, shared services
