For Earth Day 2009, here's full video of the Green Data Center panel at the recent GigaOm Green:Net 09 conference, with a panel featuring views from Yahoo, Cisco, IBM, Dell and The Uptime Institute.
The U.S. Environmental Protection Agency has chosen to launch its Energy Star for Data Centers ratings using the Power Usage Effectiveness (PUE) metric as the basis for its rankings.
A year after The Uptime Institute called for companies to appoint "energy czars," few companies have adopted the recommendation.
Data center energy audits are now starting to come with guarantees that the auditors will identify savings that recoup the cost, or the audit is free.
