Apple has announced plans to invest $2bn in a data centre in Arizona that will be powered entirely by solar panels.
The company said that it will convert the existing Mesa, Arizona facility into a command centre for its global network of data centres and include a 70MW solar farm in the plans.
The Mesa site previously housed the failed Apple glass supplier GT Advanced Technologies (GTAT), which filed for bankruptcy in October putting more than 700 jobs at risk.
GTAT had been supposed to supply "stab proof" sapphire glass for the iPhone 6, but had failed to meet Apple's quality standards.
Arizona governor Doug Ducey said that the latest news is a major boost for the state.
"Apple is by far one of the most innovative and successful companies in the world," he said in a statement.
"Its decision to bring this new facility to Mesa is a huge win for Arizona and a high testament to our business-friendly climate and talented workforce."
The news was also welcomed by Greenpeace, which said that it reinforces Apple's commitment to power its facilities using 100 per cent renewable energy.
"Apple remains the most aggressive among major IT companies in delivering on its commitments to be 100 per cent renewable, and has shown the business community that solar is ready, here and now, to power our economy," said Greenpeace senior IT sector analyst Gary Cook.
He added that the announcement should encourage policymakers and regulators to make more use of Arizona's solar power resources.
"Arizona has some of the best solar potential in the world, yet Arizona utilities and policymakers have been slow to tap the economic potential of solar, and some are still trying to slow the growth of solar," Cook said.
"If the Salt River Project can work with Apple to help power its operations with solar energy, it can surely work with the thousands of Arizona residents and businesses who want to do the same thing."
Apple has made green energy a major part of its strategy for the future even in the face of criticism from investors who argue that it adds nothing to the company's profits.
