What has Enterprise-Wide Power Management got to do with IT?


Published on

David Tebbutt discusses the context for, and the central role of, IT in an organisation's power management. He takes the listener from sustainability, through the link between climate change and energy use, all the time stressing the cost benefits of taking action. The presentation includes quick IT-powered wins for the enterprise, quick wins for IT itself and finishes with longer term suggestions which can deliver even bigger savings.

  • Freeform Dynamics is a research and analysis firm which focuses on how organisations buy and use IT and related systems. My name is David Tebbutt and I’m responsible for collaborative and green aspects of IT. For most organisations, green equates to energy use which, in turn, relates to money. The broad aim of this presentation is to show how IT fits into the transformation of energy use in the organisation Next slide: Topics (agenda)
  • I’ll go through some scene setting slides before getting into the specifics of how IT can help, both the organisation and the IT department itself. I’ll mention some quick wins for each, then finish with what might be done in the longer term. Next slide: Sustainable development
  • Given that we’re trying to sustain our planet and the people on it, as well as our own businesses, I thought I’d share the classic definition of sustainable development. This was written 22 years ago and, as an objective, it has stood the test of time. It’s about meeting present needs, not reverting to some caveman-like existence, which wouldn’t be sustainable anyway. It’s about hope and optimism coupled with a sense of responsibility Next slide: Motivation for green
  • Last year, Freeform Dynamics asked almost 1500 people what pressures drove their organisations to consider environmental matters. As you can see, regulation, cost savings and company image took the top three slots. This is unlikely to have changed much. As a driver, ‘concern for the environment’ ranked very low. Next slide: Climate and energy (Prof MacKay)
  • So, drawing these threads together, and focusing on today’s topic, I offer this quote from Professor MacKay. (pron: Mack Eye) author of a very good book on energy which manages to sidestep money, politics and greenwash. You can read it online for free or buy a copy from Amazon – not particularly green but a heck of a lot easier to read. He shows how energy is at the very heart of the main environmental issue, climate change. Next slide: Primary energy related drivers
  • Electricity is not an infinite resource and organisations have to work within the available supply. The cost of all energy sources fluctuates but the general direction is upwards. By using less and delaying expansion, we save on both operational and capital expenditures. All companies will be affected by regulatory demands – either directly or as a result of being in the supply chain to a regulated organisation. (CRC 2010) Consumers, investors and staff are examples of other stakeholders who may start to exert pressure for the organisation to be more green. It’s in all our interests to consume less Next slide: IT emissions and savings
  • These statements are paraphrased from the Smart 2020 report which sets out how IT may be instrumental in cutting our emissions. The extent to which it applies to you depends on the nature of your organisation. Do expect that, in creating savings beyond the IT department, you will probably increase its own energy demands. It is therefore important to look at both the organisational savings and those that can be made within IT itself. IT is not just part of the problem, it’s also part of the solution Next slide: But who’s responsible for the energy bills?....
  • Before I do, though, here’s some interesting and highly relevant information from the research I mentioned earlier. We asked whether IT was accountable for its electricity expenditure. The result? Just 27 percent of IT departments were directly accountable. This has to change if IT is to take more responsibility for its own power, let alone whether it is to help the rest of the organisation. Next slide: Taking the broad view (Scopes 1, 2, 3)
  • Heads of IT need to show the organisation that they have a reasonable grasp of the issues from both an IT and a business perspective. This picture shows the sources of air pollution caused by the combustion used to generate power of various kinds. Most organisations are currently focused on scopes 1 (direct) and 2 (indirect) and the staff travel element of scope 3. Depending on your organisation, you may find yourself involved in other parts of Scope 3 (contractor’s vehicles, manufacture of purchases, product use, waste disposal...) sooner or later. BSI PAS 2050 is a useful document if you need to get into lifecycle assessment. Next slide: Where IT can support the enterprise
  • I’m going to look at how IT can support the enterprise first, then look at IT itself. A lot of travel is unnecessary: people can collaborate online and work remotely. Remote sensors can be used in storage tanks and other equipment (vending m/cs?) to avoid unnecessary replenishment and maintenance visits. Invoices and other transactional documents can be made electronic Vehicle management software can blend deliveries with collections, plan routing for efficient fuel use and, indeed, monitor driving habits. Building lighting, lifts, air conditioning and installed equipment could theoretically be sensed and managed by IT. Then, of course, different industries can benefit from other IT supported energy saving measures: farming, manufacturing, energy suppliers themselves, and so on. Next slide: Enterprise quick wins
  • No-one can get the ball rolling without commitment from the top and without encouragement of staff. Although, it has to be said, you’re often pushing against an open door. The quickest wins are usually human-powered, behaviour change stuff. Avoid printing and, when needed, see if double sided and grey scale printing will be acceptable. PDF and/or print on demand rather than print brochures. Switching things off when not needed – lights, shredders, printers. Phone chargers too, if it helps form a ‘switch off’ habit. IT can help with central management of networked desktop and office equipment Bits not atoms: enable remote access working and adopt collaborative software, especially when it cuts travel (desktop video, voice, screen sharing, instant messaging and so on.) Scan documents rather than photocopy. Measure and report progress so everyone can see how they’re doing Next slide: Measure and reporting cycle
  • Measurement, reporting and action is a continuous process. It shows where most energy is being used and enables the organisation to prioritise by potential savings. Getting beyond energy cost and into energy use, we are all going to have to get better at managing our environmental impacts. Sooner or later we’re going to have to report our progress to someone: the government, shareholders or whoever. Who better to help collect and aggregate, analyse and report than IT? Next slide: The IT department
  • You probably know that the data centre spends as much energy on cooling itself as it does on powering the IT equipment in the first place. If you can cut the energy consumption of the server and storage racks, you’re doubling the electricity savings. The distributed estate is all the kit you have ‘out there’ for which you are responsible. Desktops and printers at the very least. And I mention lighting because a lot of data centres are lit up like Christmas trees when no-one’s actually in there. Next slide: Some quick IT wins
  • Some of these quick wins for IT go beyond direct energy use but, since our overall aim is to reduce our negative impact on the planet, I don’t feel too bad about including them. Remote power management refers to connected, distributed, equipment Printers: do you need so many? Maybe a short walk would deter some people from printing so much. You can set the defaults to duplex and grey scale, forcing the user to depart from that standard. Use printers with low power standby Extend the working life of equipment while it can still do a job for someone. Connected to this, buy what users need, not necessarily what they want. Can you crank up (parts of ) the data centre operating temperature to reduce the need for so much cooling? And can you virtualise your servers and storage (multi-tier) to cut the amount of equipment running or, in some cases, to absorb rapid expansion without further capital expenditure? The next slide: The longer term
  • Some things hold a lot of long term potential but they can be costly or complicated to set up. Telepresence is good for companies which want to cut their international travel and accommodation budgets. An audit of hardware and software assets can show what’s being used and how. Redundant applications and devices can be decommissioned. Thin client computing creates capital and operational savings over the longer term. The terminals last longer and emit less heat into the workplace. Cloud services in general will use energy more effectively and, of course, it won’t show up on your power bill. Remote sensing/monitoring: see what’s going on without travelling there. It’s possible to implement fine-grain control of cooling in the data centre. Add free cooling? Recover and reuse waste heat? Space, local facilities? And building management can optimise the use of energy throughout. Next slide: Conclusions
  • Quite apart from environmental considerations, energy cost and threats to its availability are two good reasons to continuously reduce its use. IT is the vehicle for dematerialisation and for providing leverage in many other ways Match your purchases to your needs. Don’t buy just because some replacement schedule says you should Everything piece of electronic equipment you buy and dispose of has profound environmental ramifications which go beyond energy. But, do remember that, that in this future world of energy constraints, IT has the potential to be the hero rather than the villain. Next slide: Thank you. Thanks BrightTALK, Questions?
  • Thank you. And thank you, BrightTALK for the opportunity to share this presentation. You’ll notice I’ve added a link to a Green IT for Dummies mini-book we wrote. You might find some interesting tips and checklists in there. Now, let’s see if we have any questions….
