Georgetown, Texas now 100 percent powered by renewable energy.

The city of Georgetown is now one of the first cities in the U.S. to run on 100 percent renewable energy.

The milestone is met after the city ended a long-term power contract in 2012, and found new options for power suppliers that would source renewable energy—like wind and solar power— from transmission lines in West Texas and the Panhandle.

On Tuesday, the city’s mayor, Dale Ross, was featured on NPR’s “All Things Considered” with Ari Shapiro to talk about the city’s move toward renewable energy.

“It’s a great economic development tool because there’s a lot of high-quality companies in this country that have robust green energy policies. Wal-Mart is one of them,” said Ross in the NPR interview. “The Wal-Mart in Georgetown can report to Bentonville that every kilowatt of energy that they bought last year was green energy from either wind or solar.”

Although the announcement is a step further toward a potential for economic development, the news isn’t anything new. In his guest column for the Austin American-Statesman, Ross discussed the city of Georgetown’s decision to fully power their municipal electric utility with renewable energy in 2015. 

The decision to move the city’s sites on renewable energy has brought millions of dollars in new investments, and offers a cost-effective and sustainable alternative to power.
