Ecology today should not be a trend nor something trivial, it should be a priority. For Google ecology is a priority for years now and the company prooved it once more. In Googles new data center, which was built in Finland at the old facilities of a mill, it was decided to use sea water for cooling. Apart from reducing the amount of river water that would be used this sea water approach takes into account the temperature difference between used and bay water. So used water is mixed with cool bay water so the temperature difference between the used and bay water will be trivial. You can take a virtual tour in Googles new Data Center through the video above.
