  CO2 emission testing of ICT equipment may need a rethink

  The traditional method of measuring the energy consumption and CO2 emissions of ICT equipment for carbon reduction purposes may not necessarily be the best, according to researchers from University of Melbourne’s partner Centre for Energy Efficient Telecommunications, and Bell Labs.

• Where is green IT heading in 2013?

  Analysts predict an uptake in trigeneration technology and data centre infrastructure management tools, and that there will be more consolidation of IT infrastructure, more sophisticated monitoring and reporting of energy use, and driving down energy costs will become a top priority for CIOs next year.

• Company size no indicator of Green IT readiness: Survey

  Company size is not necessarily an indication of an enterprise’s ability to deploy Green IT initiatives, according to findings from Fujitsu’s Green IT benchmark research for the financial services industry. In the fourth report undertaken with research partner, Connection Research, Fujitsu surveyed 638 organisations in four countries — the US, UK, Australia and India — looking at areas such as Green IT lifecycle, end-user efficiencies, enteprise and data centre efficiencies, the use of IT in carbon reduction and measurement and monitoring.

• Fixing Sydney Uni IT 'train wreck' takes cars off roads

  If IT inefficiency was measured in carbon dioxide emissions, The University of Sydney's transformation from a "train wreck" to a centrally managed, efficient fleet of client computers is like taking thousands of cars off the road, says IT director Geoffrey Brown.

• Life after IBM is all green for ISS co-founder Tom Noonan

  It was 2006, and Tom Noonan had it all. Internet Security Systems (ISS), the company he co-founded and led as CEO, was pulling in $US400 million in annual revenue and on the verge of being acquired by IBM for a whopping $US1.3 billion.

• Networks go green and save money

  Servers get most of the glory when it comes to energy management, but networking gear is about to catch up.

• NY hospital cuts power bill with thin-client virtualization

  New York City's Saint Vincent Catholic Medical Centers is saving power and money by replacing its desktop computers with thin clients running virtualized operating systems.

• Digital Gear: Gadgets to cut energy costs

  Consumer electronics like monitors, even in standby mode, can be notorious energy hogs that silently add to monthly electricity bills. Companies are coming out with smarter devices -- including power strips, plugs and electricity monitoring devices -- to help pinpoint and shut down such electricity eaters. If used correctly, the devices ultimately pay for themselves over years by cutting electricity bills and reducing greenhouse gas emissions.

• Three Rules for Managing PC Power Usage

  Nearly a third of tech's power usage comes from PCs and peripherals, according to a new Gartner report. How can companies stem this power flow? CIOs can follow a few simple rules for saving energy and reducing costs. For starters, they need to avoid falling for some of the power-saving myths swirling around PCs.

  Guidance for Calculation of Efficiency (PUE) in Data Centers

  The benefits of determining data center infrastructure efficiency as part of an effective energy management plan are widely recognised. The standard metrics of Power Usage Effectiveness (PUE) and its reciprocal Data Center Infrastructure Efficiency1 (DCIE) have emerged as recognised standards. This paper defines a standard approach to collecting data from data centers and showing how to use it to calculate PUE, with a focus on what to do with data that is confusing or incomplete.
