Green IT (Information Technology) has to do with using computing resources efficiently. Green IT can give your company significant business and environmental advantages. Green IT is an ideal way for most companies and organizations to make a significant step toward environmental preservation. That's because IT equipment is continually refreshed as a matter of company policy to remain competitive. Replacing the IT equipment with energy-efficient systems with concepts such as virtual servers, blade servers, and virtual data storage can easily reduce IT power consumption for the replaced equipment by 50 percent. Virtual servers and virtual storage allow you to significantly reduce equipment and system management costs for your data center and other IT areas. So, green IT technology is based around a solid business case without even considering the savings due to reduction in energy costs. Of all the green projects out there, green IT is truly a "win-win" direction for all companies to pursue.
Since Cloud Computing is now a major force behind green IT, several books on Cloud Computing have been added to this list.
