Reducing the environmental footprint of our data centers starts with reducing their electricity consumption. More and more cloud-computing companies are pursuing design and sitting strategies that can reduce the energy consumption of their data centers, primarily as a cost containment measure.
Yahoo is building a $150 million US dollar data center near Buffalo, New York, which will be completed in May 2010. The site was chosen in part due to the low cooling costs expected in the region and the ability to use fresh air cooling, as well as the ready access to low carbon and low-cost hydro power.

The New York Power Authority has approved 10 megawatts of low-cost hydro power for a first phase of construction for a Yahoo! facility. A second phase, expected in the spring of 2012, would receive an additional five megawatts of power.
