Facebook (a small dorm-room startup you’ve probably never heard of) plans to open a new data center in Altoona, Iowa that will run completely off of wind power. Scheduled to be operational in 2015, Facebook says the ability to run on renewable energy was a major factor in their decision to choose this location for the new center. MidAmerican Energy will build, own and operate the 138 MW wind farm that will power the center, and they aim to convert 25% of their data centers worldwide to clean energy within two years.
