Of IT (Phase 1)• Low hanging fruit• 10-20% uptake• Siloed• Savings OF IT

EXAMPLES

VirtualisationConsolidationFree coolingPower settingsMulti Functional DevicesProcurement PolicyEnd of life of assets

EXAMPLES

DC - full power all the time?

PC – Windows 7, Thin Client

Network – energy efficiency

IT Energy Consumption - In the Office

Lan &Telcoms, 7%

Mobile Telcoms, 9%

Fixed Line Telcoms, 15%

Servers, 23%

PC & Monitors, 39%

Printer, 6%

Green IT - In The Data Centre

• Data centre energy use in 2005 was 152 billion KWH

• 2% of energy use in the USA is from the Data Centre

• >1% of global emissions

• Power and Cooling is the number 1 issue for DC managers

Who is accountable for the emissions from the Data Centre?

16


• Case study omitted


Green IT - Virtualization & Cloud

• Companies can reap a 65% reduction in server count through virtualization

• $300 - $600 per year in energy savings for every server removed through virtualization based consolidation

• Cloud allows for even greater economies of scale

+ servers in a sustainable data centre

+ run on sustainable infrastructure

+ high level of utilisation

Green IT - In The Office

Desktops• Laptops use less power

• Power saving settings

• No screen savers (they’re bad!)

• The make and model selected

Printers• Multi functional devices

• Power settings

• Reporting

• Consolidation

Green IT Policy – Saves Companies Money

95% of firms with a Green IT policy save money…

Based on insights from over 310 CIOs and senior IT managers – Fujitsu: The Convenient Truth

Barriers – To a Green IT Policy

Green IT Policy

• No business drivers

• No management sponsorship

• Not enough time

• More focus on profit

• Lack of expertise

• Lack of knowledge on ROI

23


What is Green IT 2.0?Green IT is

It calls for innovation; the ability to monitor, rethink and transform all societal activities, identifying opportunities for increased efficiency & reduced emissions

Green IT 2 looks at how IT can reduce emissions from other sectors

24


IT – Can Make a Difference?

If all commuters worked from home one day a week, 5.85 billion fewer gallons of oil would be used each year

25


IT – Can Reduce Emissions

•Monitor – make emissions visible and accountable

•Rethink – innovation for greater efficiency

•Transform – dematerialisation e.g. internet sales

•Dematerialisation•SMART motor systems

•SMART logistics

•SMART buildings

•SMART grids

Green IT - Takeaways

• Corporate sustainability is here to stay; and green IT is not a fad or fashion

• Energy efficiency is not just for the data center

• Enterprises implementing green IT need process change and consulting support, not just new hardware and software

• Market green IT with a holistic vision but a tactical implementation path

• Recognize that green IT has many customer stakeholders, each with a different view of its priority and benefits
