  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.

• How An ERP System Can Help Manage Your Company's Energy Use

  A few years ago, we had the local electric company do a home energy audit. Our 19th-century house was hard to heat, and as we suspected, the inspector found we didn't have enough insulation. But our most cost-effective change turned out to be the purchase of a new refrigerator. You can't manage what you don't measure. Once you start looking at the right data, the results can lead you to solutions you hadn't imagined.

  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.

  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.
