As green computing gains prominence and as energy costs rise, more data center operators are tracking power usage efficiency (PUE) along with water usage effectiveness (WUE). But few would put that efficiency data out in the public eye.

The Facebook PUE and WUE dashboard displays real-time and 12-month averages for the Forest City campus, as well as the temperature and humidity outside.
