Apple was the largest corporate user of solar power in the US last year, says a new industry report, underlining the Cupertino company’s environmental credentials.

The Solar Means Business report was compiled by the Solar Energy Industries Association (SEIA), which says that it provides visibility into the usage of clean energy by some of the world’s biggest brands.

The top 10 companies are:

“Top companies are increasingly investing in clean, reliable solar energy because it makes economic sense,” said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association (SEIA). “During the Solar+ Decade, corporate solar investments will become even more significant as businesses use solar to fight climate change, create jobs and boost local economies. When global brands go solar, the rest of the world takes note, and this report puts the power of corporate solar investment on full display” […]

Apple’s solar facilities generate enough electricity each year to charge more than 60 billion smartphones.

Update: SEIA announced revised rankings after learning that an Equinix project shown as complete had in fact been cancelled.

The map below shows the locations of Apple’s US solar power installations, with the size of each circle corresponding to the amount of power generated.

Apple announced last year that all of its operations are now 100% powered by renewable energy.

The SEIA pointed to earlier and later milestones too.

“We’re committed to leaving the world better than we found it. After years of hard work we’re proud to have reached this significant milestone,” said Tim Cook, Apple’s CEO. “We’re going to keep pushing the boundaries of what is possible with the materials in our products, the way we recycle them, our facilities and our work with suppliers to establish new creative and forward-looking sources of renewable energy because we know the future depends on it.”
