Greenpeace attempted to slam Apple yesterday by claiming that its data centers were using too much energy and that they were powered by — gasp! — coal! Now, according to a rebuttal by Apple, Greenpeace grossly overestimated the amount of energy that Apple’s data center will use, while also claiming that its data centers will be among the most green and efficient in the world. No shocker, when we see that Al Gore is on the Board of Directors, and that Apple is normally very environmentally conscious. This smells like an attempt for Greenpeace to grab a headline.
