"Green networking" -- the practice of consolidating devices, relying more on telecommuting and videoconferencing, and using virtualization to reduce power consumption across the network -- is an offshoot of the trend towards "greening" just about everything from cars to coffee cups. That trend has encompassed IT in general, the data center and the network. But network pros don't just need lip service to stopping global warming. In this special report on green networking, we cut through the hype to present you with some real-world reasons why going green could save some green in your budget.
How green network design and equipment save money and power
How green is my
network? -- A look at the cost-savings benefit of green IT
We set the stage for our special report by explaining how going green applies to network operations, and explains why the cost-savings benefit may be more compelling (at least for now) than the urge to save the planet.
green: Design principles for efficient architectures
Green networking means efficient networking. Efficient network design combines improvements in consumption and consolidation to achieve increased manageability and lower lifecycle cost. In this tip, learn more about the specifics of efficient network design you can implement to keep your network green, as well as avoiding wastes of bandwidth, power and budget.
Energy Efficient Ethernet: Small network power savings add up
Find out how the new IEEE P802.3az Energy Efficient Ethernet project aims to deliver major energy savings by combining many small savings.
networking: Energy efficient upgrades can cut costs
Upgrading older networking products to greener, more efficient equipment can cut costs, but administrators should take a close look at total savings from switching out energy hogs like gigabit Ethernet switches for new, greener models. Scottsdale, Ariz.-based research firm In-Stat's report, "Green Networking Equipment: Who Leads and Who Lags," found that the worst offenders and early candidates for green networking equipment upgrades were gigabit Ethernet switches.
in need of a green thumb
Network power consumption comes in many forms. In this Q&A, Gary Audin, president of network consulting firm Delphi Inc., discusses the networking devices that are the biggest power drain and the best time to consider networking solutions that are a bit greener.

Building a business case for green IT
networking: Selling the idea to executives
Gary Audin knows the network consumes a lot of power. But Audin also has ideas that could change that and cut network-related power consumption to a fraction of what it is today. Used correctly, they could truly cut costs and conserve energy.
the case for green networking
More and more IT departments are being told to reduce power consumption in the data center. Cisco announced an initiative at the start of 2008 to make its products run more efficiently. In this interview, Pat Scheckel, senior director of products and solutions at Cisco partner CDW Berbee, helps you understand the green networking trend and explains why going green could be a good option for channel businesses.

How unified communications bolsters green strategies
plays into green IT strategy
Unified communications (UC) has been slow to catch on, in part because of the lack of a business case. Here, SearchUnifiedCommunications.com columnist and Yankee Group analyst Zeus Kerravala explains how UC can help a company become greener, and consequently, how companies can build a business case around UC.
