Kaiser Permanente has been named as the top user of Green IT services in 2011 by a study conducted by Computer World.
Green IT is a big trend this year as companies using IT are striving to deploy technology and practices that not only help in reducing their carbon foot print but also reduce their energy consumption and reduce their IT costs.
Computer World released the list of top 12 Green IT users after evaluating 70 organisations which had submitted their applications for a chance to feature on the list.
"In fact, these organizations have woven energy-saving initiatives into the very fabric of their IT strategies. They are tapping the collective brainpower of their IT staffs to capitalize on existing technologies such as virtualization, telepresence and solar arrays while seeking out new methods to better control their carbon footprints," Computer World wrote.
Kaiser Permanente was followed by accounting giant KPMG, State Street, Allstate Insurance and NBC Universal at the 2nd, 3rd, 4th and 5th positions respectively.
Computer World also dished out a list of 2011's top green IT vendors which was topped by Fujitsu followed by Hewlett Packard, Accenture, Microsoft and Qualcomm.
