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.

Virtualization gave data center managers some breathing room in their battle against rising energy use, but more changes are needed to keep pace with the demands of IT departments, speakers at an industry conference said Friday.

We go through some top tips on how you can establish a more environmentally friendly network

Reducing power usage and cutting carbon emissions is probably the right thing to do for the future of the planet. But keep this is mind: Green is a powerful marketing term right now and cost-savings promises are part of the marketing pitch. Like all marketing promises, results vary. One example: The amount of money a typical consumer can save by using or powering down energy-efficient computers, printers and the like is often small--in the case of an up-to-date laptop, the energy savings add up to perhaps just $10 a year.

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.

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.

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.
