In just four years, the Open Compute Project has thousands of participants and nearly 200 companies working to increase the pace of innovation in the industry.

The Open Compute Summit is underway in San Jose, California, and today, Facebook announced new contributions to OCP that will create more efficient and sustainable infrastructure worldwide.

Facebook is proud to have started this initiative, and we will continue to openly share our technologies and our learnings as we build the infrastructure required to connect the next 5 billion people.

Thanks to OCP and related efficiency work, we announced that we’ve saved nearly $2 billion in infrastructure costs over the course of the last three years. And in the last year alone, we’ve saved enough energy to power nearly 80,000 homes. The carbon savings associated with that energy efficiency are equivalent to taking 95,000 cars off the road.
