In addition to the upcoming Clarksville facility, part of the $2.5 billion will go to opening or expanding data centers in Alabama, Oregon, Virginia and Oklahoma. The company will create or add to offices in nine other states: California, Colorado, Illinois, Massachusetts, Michigan, New York, Pennsylvania, Texas and Washington. The expansion plan will add thousands of jobs and bring Google's operations to a total of 21 states and six data centers.

Google planned the Clarksville site to be a model of efficiency, and purchased enough renewable energy to offset 100 percent of its electricity use, in keeping with the company's aspirations. Today, Pichai added that the company is donating $300,000 in grant money to Goodwill of Middle Tennessee to add digital skills training to its workforce-development program.
