Accelerating the shift to renewable power

July 10, 2013 at 8:00 am PST

When we announced Cisco’s new environmental sustainability goals, one goal continued to require the most clarification from both internal and external stakeholders:  having our corporate electricity emissions factor at half of the International Energy Agency (IEA) world average.

This goal, and it’s delicate wording, perhaps only makes sense to us sustainability nerds who are immersed in the Greenhouse Gas conversation…

Given the recent market report from the IEA on renewable energy, I thought a post would be useful to explain the reasoning behind this goal, and how it helps both Cisco and the planet by including this goal in our efforts.

A Shameless Plug: The Art of the Data Center

October 19, 2012 at 10:00 am PST

One of the first things many companies do at the start of a Data Center project is look around to see what other companies have done.  Wouldn’t it be great to have a book that showcases innovative Data Centers and has insights from the people who designed and operate them?

Dinosaur Water And Data Centers

September 19, 2012 at 10:00 am PST

I love it when a small discovery causes me think about the big picture.

I’ve been researching water-related factoids for this week’s Data Center Deconstructed video on hydropower.  Along the way, I uncovered this tidbit from the U.S. Geological Survey: Read More »
