According to Forrester Research, businesses are already propelling Green IT to its “2.0” iteration. The good news is that the technologies fueling the 1.0 stage are becoming firmly established in many organizations, acting as building blocks for 2.0 endeavors that impact business processes outside of core IT competencies like supply chain management.

Certainly, everyone and their cousin is rushing to put their smog-inducing ways behind them, but the research firm confirms what we already knew. Companies are going green primarily to boost the bottom line. GreenerComputing reports:

Among the findings for why these technologies have taken off is one that gets to the heart of the future of green IT: even though the economic meltdown has hit most businesses quite hard, more and more companies plan to accelerate their green IT projects. This is because the vast majority of IT professionals see green IT as first and foremost a cost-saving measure, and secondly as a boon to the environment.

What those technologies are? Forrester drew up a list of 15, which include terms we’re all familiar with like 10 GbE networking, cloud computing services, IT energy measurement, server virtualization and more. The full list is available here. For more insights, you can order the report titled “TechRadar For I&O Professionals: Green IT 1.0 Technologies, Q2 2009” for a cool $2K.
