"In November 2014, AWS [Amazon Web Services] shared a long-term commitment to achieve 100% renewable energy usage for its global infrastructure footprint. The company called the power purchase agreement (PPA) backing the Fowler Ridge facility 'an important step toward that goal'."

Will Liquid Cooling Solutions Save Energy? [Data Centers]

Engineered Systems, Jan. 2015, by Terry Rodgers and Vali Sorell.

"Many of the liquid cooling solutions hitting today’s market still require air-to-liquid heat exchangers that provide air cooling at the individual rack where the electronic equipment is housed. The IT hardware chassis include integral fans to move the cool air through the inside of the hardware chassis to move the heat from the electronics to the air within the cabinet (or rack). Technically, this is still air cooled hardware. We have reduced the range of cooling technologies available to five distinct scenarios, and then added three additional scenarios that are becoming available (though not widespread) at this time. These scenarios will each be analyzed individually to quantify what energy efficiencies (or inefficiencies) are inherent for each."
