Surfing Yahoo's corporate blog, I found their blog entries on their data centers they opened in Central Washington in 2006 and 2007.
Their latest in Quincy.
Our second data center in Central Washington is open for business! Earlier this month we hosted more than 250 local community members and officials, contractors, and construction crew in Quincy, Washington to celebrate the opening of our first data center built from the ground up. We take great care to find the right combination of fiber connectivity, network availability, low cost of power, land and operations, and a skilled workforce to operate a state-of-the-art facility when looking for new data center locations. In Quincy and nearby Wenatchee (where we opened a data center last November), we not only found all the right resources, we were also embraced by a welcoming community.
And, their first in Wenatchee.
Our facility makes use of “green” initiatives to help us efficiently use resources. We are using hydroelectric power, which is plentiful in this area, and our building uses the cold external air to cool the inside of the data center, a special design element that helps reduce electricity needs and control cooling costs.
In addition Yahoo!'s Director of Climate and Energy strategy has a podcast.
-This Podcast features an interview with Christina Page, Yahoo!’s (YHOO) Director of Climate and Energy Strategy discussing their mandate and progress on becoming "carbon neutral”.
Christina speaks passionately about their projects in India and Brazil equivalent to taking 35,000 cars off the road or turning off the lights on the Vegas strip for two months.
