In an update to a controversial report, environmental activist group Greenpeace partly applauded Apple for taking more steps to add clean power to its data center, yet also said Apple should both be more transparent about its plans and should also be doing more.
Back in April Greenpeace slammed Apple, giving it failing marks in its ranking system, for not considering clean power enough when deciding where to locate its data centers (for more on clean power and data centers, read this detailed feature on the controversial world of clean power and data centers). In that report Greenpeace gave Google, Yahoo and Facebook higher marks than Apple.
