According to the company, the initial solar projects planned for completion by the end of 2017 will generate up to 41 MW of power at Amazon facilities in California, New Jersey, Maryland, Nevada and Delaware. Depending on the specific project, time of year and other factors, a solar installation could generate as much as 80% of a single fulfillment facility’s annual energy needs. For example, Amazon says solar panels installed on the rooftop of the Patterson, Calif., fulfillment center cover more than three-quarters of the 1.1 million-square-foot building’s rooftop and will capture California’s most generous resource to power the hundreds of Amazon Robotics utilized by associates at ground-level.

Amazon notes its recent renewable energy projects include the company’s largest wind farm to date, located in Texas. In addition, a network of the wind and solar farms in Indiana, North Carolina, Ohio, and Virginia are delivering energy onto the electric grid that powers AWS data centers. To date, Amazon says it has announced or commenced construction on projects that will generate a total of 3.6 million MW of renewable energy, and according to the 2017 State of Green Business report, the company was the leading corporate purchaser of renewable energy in the U.S. in 2016. Other examples of Amazon’s sustainability-focused projects include green corporate rooftops and the District Energy Project, which uses recycled energy for heating the company’s corporate headquarters in Seattle.
