Courtesy of Open Compute Project Facebook just opened a futuristic, energy efficient data center that cost them tens of millions of dollars to build.

The data center is the company's first -- Facebook previously leased data center space -- and it's located in Prineville, Oregon.

It's 38% more energy efficient than the standard data center and cost 24% less to build.

The best trick: Facebook released all the specs for the data center as part of a new Open Compute Project.

The goal is to move the entire data center industry forward -- and gradually reduce one of Google's big advantages.
