The Project

Behind the project

Green IT has a great potential to help society optimise resource use, save energy and reduce greenhouse gas emissions. To increase awareness on this potential, we are writing a non-profit making internationally collaborative book, released under a Creative Commons license

Why Green IT?

Today Western economices are largely characterised by service-based economies, sustained by Information and Communication Technologies (ICT). Our economies evolves around ICT: Our public sector is based on it, the financial sector is based on it, the energy sector, the transport system, the education system, the health system - all are largely dependent on Information Technology.

Our societies developed this way, because IT was able to make daily routines easier, quicker and more efficient. IT has optimised a number of processes and has helped society progress.

Globally IT is responsible for around 2%. of the world's emission of greenhouse gases. The IT sector itself contributes, through its massive consumption of energy, to greenhouse gas emissions – and thereby continuously adds to the cause of the problem. At the same time, however, the IT industry can provide the ‘technological fixes’ we need to reduce emissions and form a solid base for the Low-Carbon society. We call this Green IT.

What about climate change?

The majority of scientists today, believe that climate change is caused by the emission of greenhouse gases to the atmosphere. The most common greenhouse gas is carbon dioxide or CO2, which is emitted as a result of consumption (incineration) of fossil fuels. All sectors of society and all IT components require energy to perform their function – thus contributing to climate change.

The effects of climate change is global warming that causes melting glaciers, rising sea-levels, floods and droughts, more extreme weather events etc. All in all the effects of climate change will make life on Earth more difficult, and it will hit the hardest in low-lying and poor areas.

Climate Change and Global Warming are the effects of unsustainable consumption patterns in an industrialised world. And most people are by now convinced that we need to solve the problem, to avoid severe consequences on the environment and on our livelihoods.

IT plays an important role in this development due to its potential to further optimise processes and routines. What we want is a Low-Carbon Society where industrial processes have been optimised, energy production have been turned green (based on renewable energy) and consumption in general has been transformed to a more sustainable path.

Scope of interest

To further explore the potential for Green IT to help the climate and safe the planet - we are collecting material for a book.

We are interested in IT solutions that have a positive effect on CO2-emissions. Yet, the solutions should not only contribute to solve the problem, but should also help 'fix' the cause of the problem of climate change. A good example here, is the solution that Copenhagen Consensus Center's economists came up with (Aug 2009: Copenhagen Consensus Center): That it is cheaper to solve global warming by sending out a fleet of special built ships spraying seawater droplets into marine clouds to make them reflect more sunlight. It may solve the immediate problem, but it does not tackle the general flaws in consumption patterns that will continue to cause problems, if not attended to. Therefore it does not support our purpose to progress on the way to a Low-Carbon Society.

I have also agreed to be a contributor for later revisions of this book and will be discussing my favourite topic of Thin Client computing and desktop virtualisation.

Hat trick of Awards at Green 500

2009-06-12T15:55:00.006+01:00

Reed won a hat trick of Green awards at the Green 500 London ceremony last night.

The awards were presented by the Mayor of London, Boris Johnson, who joked that the tube strike in London had inadvertently made everyone 'greener' as they chose to walk and cycle to work, cutting their emissions in the meantime.

The first award that we won was the Green 500 Trailblazer Award. This was given to us in recognition of the fact that we have set a standard for other organisations to follow and that we have led the way in commitment and communications on carbon reduction.This was largely due to the introduction of our 'Thin Client' Terminal computer network.

The second award that we won was the Engager Award. This aimed to recognise an organisation that has achieved highly in the green learning, skills and communications of its workforce. Green500 said of Reed, "The company has delivered a comprehensive range of successful engagement activities across its entire portfolio, including: induction training; a carbon champion programme; 'switch it off' Thin Client terminals competitions; and 'Green Mondays' (an environmentally friendly news and advice service every Monday).

All activities are in place to engage employees to be more environmentally conscious in their daily activities, in order to achieve overall savings' objectives."

Finally, we were presented with a Platinum Award by the Green500. This recognises that we have made significant progress against the action plan that we agreed with the Green500 and that we continue to score highly in our carbon management processes. Next year, we will be aiming to achieve the Diamond Award, which is reserved for those organisations clearly leading the way and consistently exceeding action plan targets.

European Code of Conduct for Data Centres

2009-05-27T11:33:00.019+01:00

Last week we signed up to European Commission Code of Conduct for Data Centres

We decided to transform our enterprise data centre in 2007 into an energy efficient data centre.

The first thing we did was to increase the room temperature from 18C to 24C. We did this gradually one degree Celsius per month to gauge the effect. Modern computer equipment does not need to run below 20C and it an old mainframe legacy concept that some data centres still run at such cold temperature.

Next we turned off the humidifiers; again modern computing equipment does not need humidity of exactly 50%. We found that often one air conditioning unit was boiling bottle using a 4KW element to humidify the room while the other unit was de-humidifying the room. Just plain CRAZY!

We enforced hot and cold isles and created most efficient air flow by using blanking plates, changing air tiles and diverting under floor air flow.

We virtualised every server that could be virtualised by using 64 bit HP blade servers. You now need to business case to have a physical server.

Our HP Blade server enclosures use 90% plus power supplies and power management making them very efficient.

We consolidated our Storage using Netapp reducing the amount of spinning disks by over 500 while increasing actual capacity.

The data centre is now a lights out data centre. A sensor senses when someone is inside the room and switches the lights on. They switch off automatically when the person leaves.

We monitored electricity meter power consumption and UPS IT equipment consumption to work out Green Grid PUE and DCIE metrics

However the main investment was to replace our Stulz computer room air conditioning units for a pair of Uniflair Free-cooling units

Our legacy air conditioning equipment was ‘direct expansion’ where a refrigerant gas is used to transfer heat from inside the building (via the AC unit) to outside air (via the condensing unit). In this type of machine the complete heat transfer process is carried out by condensing & evaporating the refrigerant gas.

The new Uniflair system still relies on the same principal, however instead of relying on ‘pumping’ the refrigerant around the system, its transfers the heat to a water system which absorbs the heat generated & carries it to the roof. The key feature of this system however, is that for much of the year it can transfer enough heat from the room to the water without having to run the compressor system at all – and this is where substantial cost and environmental savings can be achieved.

When outside air temperatures are low enough, the water can simply be passed through the roof top cooler and passed back to the AC unit where it is diverted straight across the evaporator to cool the room air.

The new system also uses ‘EC’ drive fans which are the latest low energy fan drives saving approximately 33% over standard motor drives.

Benefits

There are numerous benefits to changing to the Free Cooling water cooled option

• Free cooling available for much of the year (any time it is less than 16C)
• Lower energy consumption.
• Lower refrigerant system content.
• Improved low energy fans drives.
• Great capacity control – improves room conditions & lower energy use.

Green Grid PUE Metrics

Although the free-cooling was installed in November 2008, the free cooling element was not fully active until early December 2008.

Prior to November 2008 we estimate our Data Centre PUE to have been close to 2.0 although the average legacy data centre PUE is 2.5 according to the Uptime Institute

November to December 2008 PUE 1.68

January 2009 PUE 1.29

February 2009 PUE 1.36

March 2009 PUE 1.36

Microsoft have been one of the largest names to sign the code. They have a PUE of 1.6 and have targeted 1.2

Google led the charge with one of its data centres running an average PUE of 1.11 and the rest averaging 1.19 PUE

Another idea is to use a networked energy monitor like the Ringdale Energy monitor which connects to the network via a Ethernet cable contains a web server with data logger

We will be installing this in-expensive monitor in the next few weeks

Link to the Ringdale monitor can be found here

We would certainly encourage others to sign the EU code of conduct.

BSI Green IT Conference 19th May

2009-05-25T23:00:00.001+01:00

I attended BSI's first and maybe only Green IT conference last week on 19th May at the CBI conference centre at Centre Point, off Oxford Street London.

The speakers were excellent but the attendance was very poor, whether it was scheduled too close to Green IT 09 a few weeks ago, the world recession or just poor marketing of the event I just don't know.

The number of delegates excluding speakers and BSI employees numbered 15 including myself which was cosy.

If BSI wants to run this event again I would suggest making it a free event or a virtual Green IT event where presentations are streamed to people's desks.

That said there were some good presentations and good points made to the select small audience.

Mile Gilmore, Managing Director of E-Ready who chaired the BSI Green IT conference started his introduction by stating "The very term 'Green' has as many interpretations as the number of people asked" he went on to say "I would venture that 'Green IT' is actually "Energy Efficient IT"

Ian Osborne from Intellect was the next speaker to talk about Grid computing Now! and how it is aimed championing Green IT through Grid Computing.

http://www.gridcomputingnow.org.uk

During his presentation Ian claimed "Powering processors consumes 6-10% of the data centre budget" said "It is important to get good value for carbon!"

The next presentation was David Fatscher from BSI is talking about ISO14001, PAS2050 and BS16001 standards. He said BSI was looking for users to get involved in Green IT standards he said anyone could join a committee or comment on draft standards by visiting http://www.bsigroup.com/getinvolved

David from BSI also called for IT vendors to provide "proof of greenness" after 80% of users said they had been misled by "Green wash" in a recent survey.

David Fatscher,BSI, Liam Newcombe,BCS Data Centre Specialist Group and Bob Croks,Defra then discussed what role BSI can play in shaping Green IT agenda in a discussion panel.

Next up was Liam Newcombe from the BCS DCSG on the European Commission Code of Conduct for data centres.

He started by saying "European Data centres are forecasted to use 104 TWh of energy by 2020" and quoted Paolo Bertoldi DG of European Commission JRC saying "The aim is to inform and stimulate data centre operators to reduce energy consumption in a cost effective manner"

Liam said "there was no coherent set of expert Green IT strategy" and "most information is not vendor neutral" when talking about the Green data centre.

Liam Westley, Managing Director from Tiger Computer Services AKA @westleyl on twitter spoke about the role of virtualization in Green IT. His presentation can be found on his blog at http://bit.ly/DraNI

On a lighter moment Liam showed how to Fry an egg on your PC to demonstrate how much power you are wasting http://bit.ly/6OvlD via @westleyl

Next up was Mark Taylor from Microsoft who said Microsoft wants to "help customers embrace sustainability as a way to save money as well as reducing their environmental impact" Mark said that Microsoft have signed the European Commission’s code of conduct for data centres just last week.

Following Mark's presentation was a panel including Liam Newcombe BCS, Patrick Fogarty Norman Disney & Young and Ian Osborne, Intellect to discuss data centres for the future. Cloud computing was a common theme and the McKinsey report on Cloud Computing Costs http://bit.ly/zsiIy was referenced.

Mark Cavill from Royal Mail did a presentation on their carbon emissions.

Some of his statistics included that their "CO2 emissions would fill 99 billion party balloons" "their energy consumption would power 43,731 UK homes" and
"Their landfill waste is equivalent to 11,157 fully laden Ford Transits"

He claimed Royal Mail's CO2 emissions are 993,879 tonnes per year and they will look to reduce this by 80% by 2050

His finishing quote was "The stone age did not end because the world ran out of stones and the oil age will not end because the world runs out of oil" Amory Lovins

Anja Frrench from Computer Aid International spoke about the re-use of PC's

She said 12 million PC's bought in UK in 2008 and 12.5 Million Pc's were sent to landfill over the past 5 years in the UK.

She claimed that each PC uses 240Kg of Fossil fuel, 22Kg of chemicals and 1500 litres of water to make and that 75% of the environmental cost of a PC is expended before the PC is switched on.

The day finished with Bob Croks from Defra saying what Defra were doing in regards to government Green IT strategy.

I tweeted the highlights on twitter from @geekygreen http://www.twitter.com/geekygreen You can still search on the hash tag of #BSIGreenIT

My last small complain to BSI is they printed all the presentations on recycled paper for each delegate> I would of preferred an electronic version after the event on paper.

Green IT 09 Conference

2009-05-17T07:24:00.013+01:00

I was a speaker and delegate at the Green IT Conference & Exhibition 09 (http://www.greenituk.com) at the Islington Design Centre in London on the 6th and 7th May last week. Now in its second year it attracted some very good speakers and industry leading delegates. It was slightly smaller this year obviously a knock on effect from the global recession but the major theme was on how Green IT strategies can actually help companies reduce costs to help the bottom line dispelling the myth that Green IT is more expensive or you have to be a tree hugger.

Chris Mines from Forrester Research opened the conference with his keynote after Lord Hunt, Minister for Sustainable Development and Energy Innovation pulled out of the event for medical reasons. The Green IT 09 Keynote started with Chris Mines asking "How does Green IT continue to flourish in a recession?" he answers that we must "Align eco-logy with eco-nomics” to get past the myth that Green IT is more expensive. He says we must "Start at the top of the IT stack, not the bottom, rationalise the application portfolio which in turn creates hardware consolidation".

He stated that according to Forrester research "55% of enterprises have embraced green criteria for IT procurement". He finished his keynote by saying "40% of companies say it is still too early to know whether the recession will have an impact on Green IT initiatives"

Chris slides and research on Green IT can be found here. You need to register on the Forrester site to download the material. http://www.forrester.com/greenitevent09

Next up was Gerry Pennell, CIO of London Olympics 2012 who asked the question "How will the London Olympic games of 2012 ensure that the technology is sustainable and energy efficient as possible?" He went on to say that "Sustainability is a central agenda for London 2012 including technology and IT" and includes that "Charities and schools may benefit from the disposal of 12,000 PC's after the 2012 games"

Day two keynote was hosted by an entertaining Paul Coby CIO of British Airways who started by saying "Corporate responsibility is a critical issue for the aviation industry and we need to address this through actions rather than words". He says there are four main areas of Green IT which need addressing. These are Green IT procuring, installing, running and ultimately disposing. B.A. pledged to reduce their IT Carbon footprint 25% by 2011. Some of the statistics he presented were B.A recycle 80% of their old IT equipment and give a further 10% to charities and they have saved 7,000 tonnes of CO2 by switching off PC's at night in addition to data centre power consumption reducing by 7%.

His comment on "Too much vendor Bollocks" was reported in Eweek linked below http://bit.ly/BIpCK

I enjoyed the Green IT 09 event and found it very worthwhile. I thought that the whole Green IT message and awareness is maturing.

My own presentation on day two was entitled the "The Efficient business case" and a copy is displayed below.

I also micro blogged live on twitter from the event as @Geekygreen. The posts can still be found

Green IT Jobs

2009-04-30T07:17:00.003+01:00

If the world leaders of the G20 nations are to be believed, green technology and the green economy will help bring an end to the world recession. Whether or not this is true, it is clear that many new IT jobs will be created in an attempt to stimulate a greener economy.

Let’s start with the word “green”, which has been overplayed in the IT industry so many times for different agendas. It conjures up a stereotypical image of a hippie in sandals, protesting against the spread of capitalism and impending doom. I prefer the phrase “efficient computing” to the word “green” as any IT professional can be interested in environmental and cost-saving issues.

Many of the skills required to succeed in delivering efficiency are now mainstream technical skills; it could be argued they just need re-packaging for IT professionals to become efficiency experts.

Typically, people who are employed as efficiency experts, architects and analysts will understand technologies such as virtualised servers, virtual desktops, thin clients, power management and datacentre efficiency. Server virtualisation may include Citrix Xen server, VMware ESX and Microsoft Virtual Server or some other open-source variation.

The desktop virtualisation suppliers have traditionally been Citrix with Presentation Server (now renamed Xen App) and Microsoft Terminal Services. Now a new breed of desktop virtualisation includes Citrix Xen Desktop, VMware View and Ericom Powerterm.
Thin clients are often a good, power-efficient alternative to PCs and the market is dominated by Wyse, HP and VXL.

Nevertheless, there is one area of knowledge that serves as the foundation for efficiency which is not fundamentally an IT skill – an understanding of electricity consumption.

Do you know your amps from your watts? Understanding Kilowatt hours, Kilovolt-Amps and three- or single-phase electric power is useful, as is understanding a little about electric generation and power transmission from the burning of fossil fuels through to the distribution of electricity via the national grid and substations.

IT professionals must arm themselves with an understanding of how to make the most efficient use of electricity when it enters the building. DC power distribution, efficient power supplies and three-phase power are some ways to reduce the losses experienced when stepping down from the substation to the DC power used by most PCs.

Cloud computing is one of today’s IT buzzwords and is worth following in the efficiency arena. In theory, a shared resource such as Google Apps can have higher use and therefore greater power efficiency. If the cloud datacentre is close to a green power source, such as a hydroelectric plant or a wind farm, you can minimise transmission line power losses and be even greener.
Building an efficient datacentre requires a different skill set to understand the basics of cooling and heat. You should know your hot aisles from your cold aisles and be able to speak in British thermal units. You should understand thermal surveys and some of your buzzwords should include free cooling and heat exchangers.

Naturally, technology can play an integral part in building an understanding of the issues. A Google search of the phrase “green IT” provides more than 4.5 million results; there are many green computing blogs, LinkedIn special interest groups, RSS feeds and YouTube video channels, not to mention the Twitterverse, which regularly commentates on the sustainable computing sector to keep you up to date with the latest trends.

Half the battle of implementing efficient computing is pitching the business case to the board. This is where the word “efficient” comes into its own. With the recent high costs of utility bills, it is often very simple to show tangible returns on investment. If you can present a quick return on investment based on just financial criteria with the environment element as a value-added benefit, everyone is a winner.

The great thing about the word efficiency compared to the word green is that it means different things to different groups of people.

To environmentalists it means low-carbon computing, to the IT professional it means low maintenance and most importantly, to the finance director, it means cost-efficient computing.

Data Centres Europe 2009 Presentation

2009-04-22T23:09:00.007+01:00

Today I gave a presentation as part of a panel on the Efficient Green Data Centre at the 5th Data Centres Europe 2009 Conference and Awards in the City of London. It was attended by over 300 executives.

Summary of what I said is below together with my slides.

When I started in IT over twenty years I worked with ICL mainframes where five gigabytes storage was the size of a juggernaut and modest processing power took up a size of an aircraft hanger and you needed a power station just to run it.

It’s perhaps ironic that I have spent most of the twenty two years in the IT industry working out how to get power into data centres and now have spent the last four years on ways to remove power.

Interestingly enough I attended a virtual webinar by Intel last week where they claimed that computer systems are more 2.8 million more efficient when compared to 1978 while the car industry had only managed 40% in the same time period.

Today is Earth day which started 39 years ago in 1970 and is now followed by over 1 billion people around the world to create more awareness.

I think the phrase 'Green data centre' is tainted by over hyping of Green IT or 'Green Wash' by some vendors and has cogitations of hippies in sandals proclaiming doom for the world.

In the current economic climate I prefer the word Efficient Data centre rather than Green
so I will talk about efficient data centres today.

The great thing about the word efficient is it means different things to different groups. To the CEO and CFO it means cost savings, to the environmentalists and Green IT supporters it means reduced carbon emissions and to the IT professional’s reliable and low maintenance computing.

Sometime we forget why we run data centres. The key aim of any data centre should be to cost-effectively support the technology needs of the business. The data centre should be the right level of facility and matched to the needs of the business

Data centre experts recommend building as much standardization and modularity into the hardware inventory as possible.

In our case our modular building blocks are Cisco networks, HP blade servers and Netapp Storage.

If you are going run an efficient data centre you need to use metrics such as Green Grid (PUE) Power Usage Effectiveness to measure the efficient use of cooling and plant equipment. The holy grail is a PUE of 1.0 where no energy is used for cooling or plant. The average would be 2.0 where the same amount of energy is used for facility as computing systems.

In our efficient data centre the use of 64 bit computing, server virtualization, blade servers, consolidation of storage, 90% plus power supplies and free cooling have helped us achieve a PUE of 1.3.

Research has shown that it already costs more to power and cool a server over its lifetime than the capital cost of the server so why isn’t efficiency of equipment at the top of the procurement requirements. It always amazes me that IT purchasers will fights over a a few hundred pounds for the capital cost of a server but may no attention to energy ratings and the total cost of ownership to power and cool that server in it's lifetime.

I also believe you can’t manage what you can't measure and you can't measure what you can't see.

CIO’s, IT Director’s and IT departments should be responsible for the electricity bills for the data centre and perhaps the whole company if IT consumes a significant part of the power bill.

Gartner has recently announced that Green IT is still forefront of organization’s plans, despite recessionary cutbacks.

Almost half (46 per cent) of European respondents said they expect to spend at least 15 per cent of their IT budgets on green projects in 2009

In some ways the current world recession is the catalyst that efficient green computing has been waiting for.

Hopefully we can all work towards running efficient data centres which reduce costs at the same time as reducing their impact on the environment.

Green IT in Australia

2009-04-16T22:06:00.010+01:00

I have recently returned from a business trip in Australia. Before anyone asks my carbon footprint for the flights and hotels were offset through the Carbon Neutral company.

My trip was meeting suppliers to build new Green IT infrastructure to support our Asia Pacific operations expansion and build a new data centre.

Before I left for Sydney I was told that the Asia Pacific region lagged behind Europe and the United states in Green Technology so my expectations were not high of what I might find. While it is true that end users in Australian companies have not adopted low carbon computing at the same rates as the UK it became clear that many suppliers and organisations were very knowledgeable on the subject and had products and services readily available.

While in Sydney I met with Optus, an Australian telecommunications provider who impressed me with their Green building campus just outside Sydney for which they won a Green Globe in 2008

When in Melbourne I had a early morning breakfast meeting with Dr Turlough Guerin who is Group Manager Environment for Telstra, the primary Telecommunications provider in Australia. Turlough gave me a good insight to the improvements Australian companies are making in Green technology and their environment impact. Turlough's Green Files blog can be found linked below.

http://www.nowwearetalking.com.au/blogs/green-files

Turlough also told me about Bianca Wirth, another Technololist working with Microsoft Australia who is passionate about Green Technology. While I didn't get the opportunity to meet up with Bianca we have exchanged a few emails during and since my visit. Bianca blogs under the name of Little Miss Enviro Geek at http://blogs.technet.com/lmeg/ and her other website is Green IT Strategy http://www.greenitstrategy.com/ which has some good Green IT resources and links.

While in Australia I was micro blogging on Twitter under the name of @GeekyGreen at http://www.twitter.com/geekygreen with a local theme of Australia Green IT (when in rome and all that..... ) There are plenty of websites, blogs and events in Australia on Green computing.

I toured over eight data centres in Sydney and Melbourne and Green is very much on the radar with all of them. The one that stood out for me was Interactive data centre at Port Melbourne. Their managing director and novelist Christopher Ride who I met really understands what it means to be green and they have become the first to offer 100% Green energy in their data centre (a world first they claim).

On a brief trip to the capital Canberra I was encouraged to hear the Australian federal government and DEWR are embracing Green IT. They are also in the process of pushing through Carbon Emission Trading bill.

I look forward to doing business with many of the forward thinking green IT suppliers in Australia in the coming months.

I also became aware of a forward thinking Australian organisation called "ComputersOff.org" they launched a hilarious video on Youtube called "Naked Tuesdays" which is below and is a fun way of getting the message across.

On Saturday evening on March 28th I sat in Sydney Harbour to experience Earth Hour which was a great experiece.

I learnt that Earth Hour was founded by WWF Australia in Sydney in 2007 as a Citywide event which is now a global campaign backed by the UN and claims to have reached 1 billion people in 2009.

Below is my experience of Earth Hour from the Opera Bar just behind Sydney Opera House

Xen desktop The missing part of the jigsaw for desktop virtualisation

2009-04-14T16:30:00.007+01:00

If you have been reading my blog and case studies you will know that we have virtualized 95% of our desktops over the past three years. This now represents nearly 5,800 Wyse Thin Client terminals and over 100 Wyse Thin Client laptops across the whole enterprise which is 270 locations through the UK, Europe and Asia Pacific.

This strategy together with server virtualization and our Green data centre has been fundamental in reducing our carbon footprint by 2,500 tons per annum and picking up a hat trick of awards along the way during 2008.

However, we are not satisfied with 95%!

I want 100% desktop virtualization by the end of 2009 with PC's and laptops retired across the company so they become a distant memory.

This is not just a green thing but a security, flexibility and cost saving strategy.

The reason that 5% of my enterprise is still using PC's and laptops is common in many organizations.They tend to be the difficult and technically demanding end users to convert to Citrix Xenapp. Marketing departments where multimedia is used is one common group and of course the IT departments who want control over their own desktop space and registry settings are another obvious group.

Enter Xen Desktop as the missing piece of the jigsaw. I have been piloting this technology myself for the past six months and I must say I am very impressed. This allows me to deliver a full functioning unrestricted virtual Windows XP desktop through a Wyse thin client, my ASUS EEEPC, my Apple iphone or through any device with Microsoft Internet Explorer and a Citrix plug-in.

The multimedia capability is very good too; on a recent business trip I was able to stream UK BBC TV programmes via my Slingmedia Slingbox to my virtual desktop without losing speech sync and with a smooth video stream. You could never do that with Microsoft RDP.

I will be giving a presentation on this very topic about Xen Desktop at this year’s Citrix Iforum 2009 in Edinburgh Scotland on Tuesday afternoon 16th June 2009

Citrix Iforum is on from 15th to 17th June. Maybe see you there.

Free Cooling in the Green Data Centre

2009-01-31T10:27:00.005Z

We have recently installed a new Free Cooling air conditioning system for our primary Green Data Centre from Uniflair. This system uses chilled water which removes the need to run tradional compressers when the outside temperture is 8 degrees less than the data centre. We run our data centre at between 23-24 degrees celius so we get free cooling when the outside temperture is lower 15 degrees celius. This system went live in November 2008 and in the first three months the temperture hasn't risen above 15 degrees in the UK.

In total, free cooling reduces the energy consumption of a standardcooling system by 20 percent. Most of the savings comes from the chiller — with the chiller using 32 percent less energy than the chiller inthe case without free cooling. The dry coolers require 1.46 times as muchenergy in free cooling than in a standard cooling.

Green Computing in Iraq

2008-11-30T20:26:00.000Z

In late November one of my technical team (Haider Kadhim) who was born in Iraq travelled to Baghdad, Iraq to present the Reed Green Computing Case Study in Arabic at the AEC 08 conference at Hotel Al-Rasheed.

The conference was attended by many of Iraqi government ministries and there was a lot of interest.

GREEN PROJECT OF THE YEAR SUBMISSION: REED MANAGED SERVICES

Return On Investment ROI

Reed Managed Services delivers managed IT services across the Reed Group of companies at a monthly fee per desktop, across a network of over 4000 IT knowledge based users. The head of IT services is Sean Whetstone.

The decision to implement thin computing was driven by a goal of achieving real reductions in energy consumption from IT; and a separate goal on increased operational efficiencies while improving the quality of IT provision.

The 12 month project delivered clear ROI in key areas: reduced hourly power consumption by 5.4 million KW hours of power; reduced annual IT spend by 20% and delivered greater flexibility and security through use of Wyse thin client terminals, centralised data and applications, consolidated data centre infrastructure and virtualisation software

Innovation

Few other major corporates have chosen to switch from a PC to a thin client computing model on such a large scale. The project saw the complete replacement of all 4500 desktop PCs with a thin computing solution based on Wyse thin client terminals; and new data centre infrastructure based on 64-bit blade servers and virtualisation software.

This change delivered major energy consumption savings and enabled greener working practices for all staff. Previously PCs had to be left turned on 24x7 to allow overnight software patching. With thin clients there is no need for this practice and the changes are applied centrally on Wyse management software. The faster start-up time of the Wyse terminals mean staff switch off their terminals at lunchtime and the end of their working day.

Thin clients delivered other benefits including remote working with staff able to log onto their personal settings at any thin client terminal in any office; and the elimination of local workstation storage and centralised storage of data and applications meant critical information was secure and always backed up.

Reed uses its new thin computing infrastructure to transform how it delivers computer services internationally. With its UK-based central data centre running 24X7, Reed can provide IT services via Wyse thin clients to its Australia operations on the same servers at a time when those servers would otherwise be standing idle because it is night time in Western Europe.

The choice of more energy efficient servers meant lower heat emissions, enabling the data centre to operate at a higher temperature and thus reduce the need for air conditioning.- further helping to cut electrical consumption.

Future Growth

Thin computing model on a large scale makes it much easier for Reed to respond to future expansion nationally and internationally. This was demonstrated when Reed was able to establish a new remote office in Australia in less than four weeks because of the more flexible IT infrastructure available.

Management

Reed recognised that the decision to go for thin computing had to be carefully managed with both the board and staff. A three month trial demonstrated to the board that the solution was easy to set up and manage, in addition to being economic and environmentally-friendly to run.

But Reed’s IT division also had to convince the end-users. “We had a lot to prove: taking away someone’s PC and replacing it with a thin terminal is quite a dramatic move for most people to become comfortable with, and we were expecting a lot of resistance”: said Sean Whetstone, Head of IT Services.

Reed worked in close collaboration with Wyse to implement the solution within as short a timeframe as possible. Reed replaced all of its 4500 PCs in 10 weeks. A swift and smooth implementation helped to win over staff.

Excellence

Within a year of migrating to a thin computing model, Wyse thin computers have helped Reed achieve its goal of significantly reducing its carbon footprint.

In replacing the PCs with thin terminals across all locations, Reed witnessed a dramatic reduction in energy consumption – approximately 5.4 million KW hours of power – one of the main causes of carbon emissions. These, combined with halving the number of storage drives and reducing the number of servers by a factor of 20, have resulted in a 20% reduction in Reed’s annual IT budget.

“Cutting our IT budget by 20% through thin clients, virtualisation, as well as achieving reduced energy consumption is a tremendous result for us,” concludes Whetstone. “Not only have we met our objective to significantly reduce our carbon emissions, but we have also discovered a more cost-efficient way of operating and growing our business, which will continue to reduce our operating costs for years to come.”

Green IT Expo Day One

2008-11-04T17:35:00.006Z

I visited the Green IT Expo in the Barbican Exhibition Halls in London today.

Day one started with Chris Mines from analyst gr op Forrester.

He self confessed he had flown in from America and therefore increasing his own personal carbon footprint.

He started by re-defining "Green IT" as "IT suppliers and their customers reducing the harmful environmental impacts of computing"

He then highlighted three steps that origination's could take to green their computer operations

1) Eco + Eco (Economics + Ecology)

Myth: Green IT is more expensive

Reality: Green IT will often have a lower TCO (Total Cost of Ownership)

2) Combine Technology with process and People.

Myth: New Technology will dramatically reduce carbon footprint

Reality: There is no technical magic bullet, business processes and employee behaviour as just as important

3) Position IT as a leader for the business

Myth: IT has enough to do just making computing greener

Reality: IT must help green the other 90% of the company's operations

Chris summarised by repeating Now is the time to move Green IT from awareness to action.

Some of the stats can be found at http://www.forrester.com/greenitexpo2008

You need to register to view the information on the website.

The second keynote I attended was delivered by Colette Maloney, Head of ICT for Sustainable Growth (Unit H4) for the European Commission. She explained 11 research projects were being funded on sustainable computing to the tune of twenty millions euros in 2008. In 2009 the funding was set to grow to 50 million euros of funding.

She also quoted European president Barroso as saying "The ICT sector is crucial to the huge forward looking project we are embarking upon with our climate policy"

Another keynote I watched that impressed me was Chris Bullock who was representing Climate Savers

He suggested three steps for all companies to adopt as a minimum:

1. Turn on Computer power management

2. Buy energy efficient computers

3. Tell others about it

You can sign up as a company or an individual at http://www.climatesaverscomputing.org/

I signed up my company and as an individual on the train ride home using my ASUS EEEPC.

I visited a number of stands which I will summarise tomorrow along side Day two.

Computer World UK Interview

Green matters: Reed runs thin and green

Reed Managed Services’ early interest in doing environmentally friendly business has earned it the reputation of being a green activist in IT matters, too. Head of IT services, Sean Whetstone, explains how measuring the carbon outputs of IT activities is the foundation of his work.
By Helen Beckett

Reed Managed Services has the advantage having an eco warrior chairman at the helm: James Reed hosts a green conference call every week and signed up to Prince Charles’ mayday environmental summit earlier this year. His interest is the reason the recruitment and HR service provider got into carbon counting early - 2005 is practically ancient history in terms of business involvement in green affairs, after all.

Head of IT services, Sean Whetstone believes this personal passion is what drives the green business agenda. Unusually, Reed Managed Services can substantiate its professed green credentials with a raft of facts and figures that show its carbon consumption and reduction. An implementation of thin client technology has reduced energy consumption at Reed by 5.4 million kWh of power, which is equivalent to 2,800 tonnes of CO2 per annum.
But it’s a passionate concern for the planet that has led the company to embrace complex calculations and measurements rather than a fondness for bean counting or reducing energy bills. Whetstone also sees this as a motivating force in the grass roots engagement with greener practices at the company. "People really want to get involved in climate change prevention - they’d be less motivated to change their behaviour if it was simply to save the company a few pennies," he says. Being has certainly made his job easier – "there is commitment and funding from the board." These precious commodities have been ploughed into two major IT initiatives to date. Ripping out 4,500 PCs on the desktop switching to thin client devices and consolidating the data centre using blade technology and virtualisation.

Whetstone trialled thin client terminals from Wyse Technology for three months.
Users were able to securely log into a session and access files from any workstation, whether they were working from home or from another office, without going through complicated log-on and networking procedures. The fast start-up time of the terminals also meant that Reed could encourage staff to switch off at lunchtime and at the end of the working day.
Redesigning the datacentre also entailed adopting new mindset. “I came from a government mainframe environment where the datacentre was like a fridge and the humidity was 50%,” says Whetstone. Like most other businesses, Reed ran its data centre at 18 degrees C but has since raised that to 24 and has also switched the humidifiers off.

The entire investment into greener desktop and datacentre was £3 million but the business case shows it will pay for itself in 18 months. And according to Whetstone the IT collateral makes the early action very worthwhile. "The outcome is not only green, it’s secure and cost effective."

Have you calculated the carbon footprint of your IT activities?
Yes - not only for IT but the whole of the organisation. We did our first audit in 2005with Carbon Neutral and calculated that the IT department had a carbon footprint of 4,500 tonnes. We included the commute emissions of our staff within that but not the cost of delivery of IT kit – none of the vendors we spoke to have worked it out.
Does your department pay for the energy consumed by your organisation’s IT equipment?
No, not all of it but I have visibility of the costs. Cutting carbon was a business target and so it was important to know the size of energy bills. The electricity bill for the data centre is a line on my P&L sheet, for example, but I also know the electricity bill for every property so I could measure the impact of introducing thin clients onto the desktop.
Does IT play a role in defining green strategy in the organisation?
We have a ‘mayday’ champion appointed for the whole company, a graduate whose sole responsibility is to promote and coordinate environmental issues. Plus, the company has weekly green committee that meets that is chaired by the company chairman, James Reed. IT has a big input into this because our energy consumption is a significant factor.
Which environmental policy have you implemented that you feel has been particularly significant?

Our thin client implementation was a massive one: we replaced an 185 kWh device - that was on 14 hours longer a day and weekends - with a 17.2 kWh device. It’s shaved 25% off the energy bill – that’s around £100,000 a year.

Do you have an identified person within IT who is now responsible for green IT?
It sits on my shoulders – I am Mr Green. As well as internal strategy and policies I talk at external events – I was on the House of Commons Working Committee and am now advising Defra (Department for environment, food and rural affairs) too. Because we started our work early, we’re seen as a benchmark for other industries.

Being Green at work

2007-09-30T10:33:00.000+01:00

During 2005 the company I work for became Carbon Neutral by offsetting it's carbon by partnering with the Carbon Neutral Company http://www.carbonneutral.com/. I know there has been some bad press recently about off setting carbon but it is a start and stepping stone to the next stage.

We also purchase our electricity from a Green energy supplier.

In May this year the company I work for signed up for H.R.H. Prince of Wales pledge to become a "May Day Company" http://www.bitc.org.uk/what_we_do/may_day/index.html

Being Head of I.T Services I have responsibility for the I.T. Infrastructure

During 2006 we replaced our I.T Infrastructure replacing over 4,500 P.C's (using on average 180 Watts 24 x 7 = 168 hours per week) with 4,500 Wyse V30 Thin Client Terminals using 17.2 Watts 50 hours per week. We also switched to Citrix and VMWARE using 64 bit HP Blade servers. The result has been a reduction of over 400 servers through 64 bit computing, Citrix and VMWARE retirement and consolidation.

We are making good improvements into making our data centres Green. We maximize use of air conditioning using cold and hot isles and have increased the temperature from 18-19C to 22C .

Last year we reduced one of data centres power requirements by 188,000 KwH but this is just the start.

During 2006 we switched all printing and photo copying to duplex/double sided. Considering we print 29 million pages per year this is massive reduction in paper.

As a Green champion in the company I work for we plan many more initiatives over the next year and plan to publicly state a carbon reduction target we will work towards.
