Apple Commits To 100% Renewable Energy Sources for NC Data Center
judgecorp writes "Stung by continued criticism from Greenpeace and protests at Apple's headquarters over its use of electricity from non-renewable sources, Apple has promised that its data center in Maiden, North Carolina will use 100 percent renewable electricity, 60 percent of it generated by Apple itself. The update is possible because it is building a second giant solar array, and because its data center only needs 20MW at full capacity, instead of the 100MW which Greenpeace had estimated."
I might be feeding a troll here, but I did a quick search and found this. Depending on the type of cell and the manufacturing process and where the panels will be deployed, somewhere between 1 and 3 years, while panels typically come with a 20 year warranty and will likely last 30 to 40 years. That study is from 2000, manufacturing may have become more efficient since then.
