Unless companies like overspending on electricity, green technology makes sense

I have to be honest. When people first started talking about green computing at the back end of last year, I was not sure what they meant.

Their enthusiasm often made the concept sound worthy, but it was only when the conversation turned to what we were going to do to monitor and reduce energy consumption that the lights came on – no pun intended, of course.

I then realised that if reducing energy use and cost was the definition of green computing, then the concept was already firmly on our agenda – at Betfair we were already examining the options and innovative technology available to help us use power more efficiently.

Every organisation should behave responsibly towards its customers, staff and stakeholders, and this ideal is very much part of our culture. But I certainly do not see myself as any kind of eco-warrior as we are, after all, a service business, not a factory-based organisation consuming vast amounts of power and pouring emissions into the atmosphere.

I could understand the incentive to reduce use of expensive electricity, but surely our impact elsewhere must be minimal?

However, when I read a recent report from a United Nations research group it shocked me to find that manufacturing the average PC requires 10 times the weight of the product in chemicals and fossil fuels.

Suddenly the banks of PCs sitting in our engineering department did not seem quite so innocuous.

The definition I find most useful for green computing is that it is the study and practice of using computing resources efficiently. And if we can find ways to address social responsibility and minimise environmental impact while also saving our organisation money, this is not just green computing – this is plain common sense.

So what has Betfair been doing to make its use of computer resources more efficient? There are two main technology strands to our efforts so far. These involve making better choices for technology and increasing our use of virtualisation.

We had a requirement to support 60 Sun Solaris databases; we estimated that running the systems would take 16 kilowatts of power. But after putting energy consumption on the agenda, we decided to become early adopters of Sun’s CoolThreads technology. This choice helped to reduce the power required to three kilowatts.

We also chose energy-efficient, four-core Opteron front-end web servers, which provided at least a 50 per cent energy saving against equivalent technology.

As well as focusing on more energy-efficient machines, we have introduced a policy of virtualisation to increase the use of our existing equipment.

This policy reduces the need to buy more equipment, and consequently also reduces the growth of our power requirements.

Storage virtualisation is a key technology for chief information officers to examine when they are looking for power reductions. The 40TB cut we have achieved at Betfair represents a power saving of more than 60 per cent.

However, even with these principles we cannot avoid the fact that some equipment must eventually be replaced. So in addition to developing a strong culture of recycling at Betfair, we have signed up to Computer Aid International.

Computer Aid has shipped more than 80,000 PCs to more than 100 countries for use in locations such as schools and hospitals. Any organisation can sign up on-line and it is certainly a great deal more attractive than the alternative of redundant kit languishing in landfill sites both here and abroad, leaking toxic chemicals.

All of these steps and decisions have been voluntary. But there are also compliance issues to be considered, such as the Restriction of Hazardous Substances (RoHS) Directive that restricts the use of certain hazardous substances in electrical and electronic equipment. The directive has guided our major equipment purchases for a considerable period of time.

Staff responsible for improvements now have the green computing bit firmly between their teeth, and have galloped ahead with innovation to improve performance – and to increase the number of products we have been able to produce.

Of course, we can always do more. For example, we could enforce a mandatory requirement to turn off PCs and monitors at night across the company – something that is now under discussion. Overall, the future for the organisation is definitely green.

Rorie's hit the nail on the head re. green technology and the huge cost benefits that can be gained.

The Business Performance Management (BPM) Forum is undertaking two milestone thought leadership research initiatives called Uptime @ Crunch Time and Lean and Green Leadership. We are conducting a 2 surveys targeted towards IT datacenter professionals relating to green computing and uptime issues. Would it be possible for you to include the link to these surveys on your blog?

Uptime @ Crunch Time (http://www.uptimeatcrunchtime.com/):
As data storage demands mushroom, all too often concerns over optimized data performance, scalability, and resilience are ignored. To gauge the awareness of the criticality of uninterrupted, high speed data access in high-demand events and industries, the BPM Forum is undertaking a landmark initiative, Uptime @ Crunch Time, to benchmark how leading IT professionals and business executives view, control and maintain continuous data uptime during critical business scenarios.

Lean and Green (http://www.getleanandgreen.org/):
In a world of pervasive energy shortfall and rampant computer waste, IT executives, operations influencers and buyers are seeking cost-effective ways to implement green practices across the enterprise. The Lean and Green Leadership initiative seeks to increase and enhance executive discussion and awareness around the ways IT organizations can reduce energy drain and impact business gain by consolidating storage systems, embracing efficient computing practices, and introducing power-saving techniques. The authority leadership program will examine ways to address the accelerating energy demands and rampant waste of the data center, along with methods to increase IT yield and data productivity.
I look forward to your response!
