Project Dolphin Solar Farm - the name Apple have given for its solar farm that will power its massive data center in Maiden, North Carolina. It will reportedly be built on 171 acres of land across the street from Apple's planned $1 billion data center, which has the code name Project Dolphin, but is now called iDataCenter. iDataCenter is said to server Apple's cloud-based service, iCloud.

This is the first time Apple has opted for clean power and greener data centers, as Greenpeace estimated that Apple source only 6-percent of the power for its data centers from clean power (which is the worst on Greenpeace's list) and gave Apple a big, fat "F" for its decisions to build its data centers in areas with little clean power. Funnily enough, North Carolina has one of the dirtiest electrical grids in America, with 61-percent of the power coming from coal, and 31-percent from nuclear.

But, it's one of the cheapest when it comes to the price of power, something Apple may have liked when deciding to build its data center there.
