Apple just released its 2012 environmental report, detailing all the ways it’s conserving energy and working to make Mother Earth a slightly cleaner place. A highlight of that effort is clearly the company’s data center in Maiden, North Carolina. The giant white-roofed server bunker will soon be home to the largest end user-owned solar array in the US — covering 100 acres and producing 42 million kWh of electricity each year. The 20-megawatt installation is only the beginning too. A five-megawatt fuel cell facility will soon be going up alongside it. Hit up the source link for the full report, but be forewarned, it comes only in PDF format.
