Making the case for green IT

At the AlwaysOn GoingGreen conference in Sausalito, Calif., technology executives discuss the motives behind going green.

Rob Ober, an LSI fellow, says the issue is more complicated: IT managers can buy a more efficient machine every two years, but no one has yet figured out what to do with the old ones.
