Allow me to point you to a recent HP video profile story produced by ZDNet.

The video summarises our green practices and technologies and includes interviews with Bonnie Nixon, our Director of Environmental Sustainability and Brian Brouillette, our Vice President of Solutions Infrastructure. The video provides a nice overview of how we at HP strive to reduce the carbon footprint of our company. Definitely worth watching. You can watch the video here. 

Enjoy
