The Cupertino, California-based technology giant has switched many of its electricity-hungry data centers to renewable energy. The data centers serve Apple's Internet storage and iCloud data.
The data center in Maiden, North Carolina produces about 167 million kilowatt hours per year, according to reports, from a 100-acre solar energy facility and installed fuel cells built by Bloom Energy.
Apple switched on these on-site renewable energy generators in December, and the system provides about 60 percent of the power the data center uses. The rest Apple purchases, but officials said this electricity comes from renewable sources.
Apple data centers and corporate facilities in Cork, Ireland; Sacremento, California and Austin, Texas also operate on renewable energy.
Apple has pledged to source 75 percent of all the power used throughout the company from renewable energy.
