MacRumors has a post on Greenpeace's position on Apple's Maiden Data Center. Much of what is referenced comes from Data Center Knowledge.
Greenpeace announced yesterday that it has prepared an updated report on Apple's energy usage based on the new information, but as noted by Data Center Knowledge's Rich Miller, the group still seems to be being overly critical in its grading of Apple, even continuing to make up its own estimates of the North Carolina data center's energy usage rather than believing Apple's public statements.
In its initial report in April, Greenpeace estimated Apple’s power use in North Carolina at a whopping 100 megawatts. The group has reduced that slightly to 81 megawatts, dismissing the company’s disclosure that it expects draw about 20 megawatts at full capacity.
You can read the post to get a pro-Apple position vs. Greenpeace.
Another post by GigaOm's Katie Fehrenbacher goes into more detail on the Greenpeace position.
But, then I read the comments on the MacRumors site. I think it is pretty clear these people love their Apple products more than Greenpeace. I don't think Greenpeace has ever attacked a company with a customer loyalty so high to criticize Greenpeace itself. This is going to be interesting to see played out over the years.
