By the end of 2012, the company hopes to power its data center in Maiden, N.C., entirely from renewable energy sources. That amounts to 20 megawatts of electricity draw at full capacity.
Apple’s on-site installations will include two solar arrays: the first, 100-acre 20-megawatt installation is being built on the same site as the data center. It will produce approximately 42 million kilowatt-hours of electricity annually. The second 100-acre site, located a few miles from the data center’s location, will be configured to produce about the same amount of energy per year.
