#9 Google’s green data centers

Inside the Council Bluffs, Lowa data center there is over 115,000 square feet of space. There are 9 more such data centers owned by Google. These data centers are basic to run Google’s internet services like Google Search, Google+, Gmail, its cloud services and others.

At the Georgia data center, Google built an evaporative cooling system, which uses both outside air and chilled sprayed water to cool servers. Google in its blog post said that this evaporative cooling process commonly uses “hundreds of thousands of gallons of water a day.”

To counter such a huge waste of water, Google has turned to chilly outside air and even seawater for greener ways to cool its data centers. The search giant has also tapped into recycled waste water to cool a data center in Douglas County, Georgia. It’s the first time Google has used recycled waste water for a data center in the U.S. and the system was financed by Google and owned by the local water authority.
