With the completion of a 1.1 megawatt solar rooftop solar array at its North Las Vegas fulfillment center, Amazon has installed 17 rooftop solar arrays in the US in the past 14 months. The company is looking to become the latest IT giant to become 100 percent powered by renewable energy, like its peers Google and Apple.

The company aims to complete at least 50 rooftop solar systems across the globe by 2020. Amazon is quickly catching up with other companies. It ranked third for new corporate onsite solar installations in the annual Solar Means Business Report US in 2017 and 10th overall for for its installed solar power capacity.

“It’s exciting to see 17 of these solar rooftop systems go live in just over one year,” said Tom Chandlee, Senior Manager of Renewable Energy at Amazon. “These projects are important steps toward our renewable energy goal and we hope they inspire our employees, customers, and communities as we work together to bring more renewable energy online in the coming months and years.”

The latest installation covers 813,000 square feet of roof space, an array the size of 3.5 football fields, the company said. It’s also the company’s onsite second installation in Nevada.

“Projects like Amazon’s solar rooftop installation will help propel Nevada’s economy into the future and solidify our state’s position as the Innovation State. It will also contribute to the state’s leadership in solar energy production and green jobs,” said Sen. Catherine Cortez Masto (D). “Nevada shares Amazon’s commitment to promoting sustainability and championing renewable energy projects that are good for the environment and that create good paying jobs for Nevadans.”

Amazon’s also completed solar arrays on fulfillment center rooftops in California, Maryland, and New Jersey. Beyond that the company has recently installed wind projects in Indiana, North Carolina, Ohio, and Texas. The company also is pursing giant solar projects offsite. Altogether it now has 28 wind and solar energy projects across the US. The company said it now has 3.6 million megawatt hours of renewable energy completed or under construction.
