Apple gave NBC’s Today a rare look inside its Maiden, NC data center during a segment on the company’s efforts to use more green energy (via AppleInsider). Apple’s NC data center is powered entirely by reusable energy, including a massive solar farm and on-site biogas cells.

Jackson notes that Apple sometimes generates even more solar power than it needs, which allows the excess to go toward supplying energy to the city’s power grid

The segment also includes a look at the inner workings of the data center, which serves as the center of Apple’s iCloud and other online operations. You can see the entire clip below.
