In this 14-minute podcast, Dan Esty, one of the world's leading experts

on corporate environmental strategy, and Dennis Quan, CTO of IBM High Performance On

Demand Solutions, look at the explosion of power use by today's rapidly growing data

centers. A recent EPA report estimated data centers use 1.5 percent of the total

electricity generated in the United States — a figure that has doubled in the past

five years and will double again by 2011 at an operating cost of $7.4 billion

annually. The problem and solutions, including a smarter approach to IT, are

discussed.
