The Greenpeace organization released on Tuesday (Apr 17th) a report in which they accuse Amazon, Apple and Microsoft of relying heavily on "dirty" energy to power their cloud data centers with its rapid growing, and so they do not bother to find "green" solutions.
Greenpeace criticized Amazon for not having transparency on how they are powering their own services. Greenpeace said Amazon does have the needed resources, but the company does not make the effort to invest in renewable energy. They argued saying that cloud computing is more environmentally friendly than traditional computing ever was, but made no comments on energy sources.
Apple was criticized for using coal energy. Greenpeace said the company has enough available cash to make a difference, but yet their huge data center in North Carolina is powered by coal energy. Apple responded to Greenpeace's statements saying that North Carolina's data center is probably the world's "greenest" data center ever built.
Lastly, Microsoft earned a higher score than Apple, for example, but the software giant was criticized for having a large part of its energy coming from coal and nuclear power plants in Virginia. Microsoft refused to comment on Greenpeace's statement.
