First building to use wind turbines turns five

 
The Bahrain World Trade Center, located in Manama, Bahrain, was completed on April 8, 2008. It was the very first skyscraper to incorporate commercial-scale wind turbines into its building design. The 787-foot, 50-floor tower has inspired others to experiment with wind turbine concepts, although few have actually reached the construction stage.

An aside for you science fiction fans: You might recognize the Bahrain World Trade Center from the 2009 Syfy made-for-TV movie Annihilation Earth.
