A few days after the publication of a report by Greenpeace pointing to the adverse effects that could be cloud computing and its power plants (data center) on the environment, Microsoft obviously piqued, decided to respond. Our colleagues of Cloud Computing Journal published an email from Francois Ajanta (pictured), director of operations "Environmental Sustainability" in the publisher of Redmond.

Microsoft, which had been listed with Amazon, Yahoo and IBM, among others, as one of the major players in the Cloud to make efforts in reducing carbon emissions, says the impact on the environment is systematically taken into account by Redmond in its activities. And to cite the case of a data center located in Quincy in Washington State that uses water power as the primary source or that of Dublin, naturally cooled by outside air. Recall that in its report, Greenpeace had strongly pinned Facebook.

The social network provides for building its first data center in Oregon. But also provides the power, partly via the Electricity produced by a company that derives its energy from coal, among others.
