What's behind green-tech initiatives and the choices

The impetus for green IT projects -- not just those in the Green 15 -- run the gamut: Some companies are struggling with limited space and power to keep pace with their ever-increasing technological needs, and thus need to eliminate and consolidate machines. Some seek to put a dent in soaring energy bills through power management and improved heating and cooling. Some are committed to protecting the environment by reducing waste and cutting their carbon emissions. And some are, quite frankly, investing in green technology not for the environmental benefits -- nor necessarily the lower power bills -- but because it happens to meet another business need. The green payoff is a happy bonus.

The goal with the Green 15, however, wasn't to simply reward initiatives based on what inspired them. Rather, we considered the net effects of the projects, taking into account what technologies and best practices were applied to a business goal and what the ultimate result was in terms of environmental benefits, the business implications, and the lessons learned to be applied to future initiatives.
