Frequent readers of my Sustainable IT blog may have noticed a recurring them in my posts over the past three years: Much of green IT's success depends heavily on making the most out of your resources, whether you're talking about servers and PCs, CRAC units and power supplies, or watts of electricity and gallons of fuels. Cliché though they may be, adages such as "Waste not, want not" and "Do more with less" summarize the case for green IT pretty well.
Consider, for example, the numerous data center operators who have grappled with limited floor space, a tight budget, and limited amount of available power. Rather than spending valuable time and piles of ducats on an expansion or a new facility, many of these organizations have embraced green tech -- virtualization, application mapping, power management, free cooling, and more -- to make better use of what they had. The end result has been significant savings, freeing up resources for other business-critical projects.
Sustainable technology has proven its cost-saving value in areas beyond the data center as well. On the desktop, companies are saving thousands of dollars cutting electricity waste with PC power management and thin clients or desktop virtualization. At the printer station and in the copy room, organizations are reaping huge savings with print management to slash paper and ink waste. Teleconferencing, videoconferencing, and other real-time collaboration tools are helping companies cut (or eliminate) the time and expense associated with travel.
