On February 11, Landsat 8 captured the Ivanpah Solar Electric Generating System, southwest of Las Vegas, near Primm, Nevada. Officially opening this week, the giant solar-power farm spans over five square miles of federal land and includes three towers, each the height of a 40-story building, and more than 350,000 heliostat mirrors that are the size of a garage door. The mirrors reflect sunlight onto boilers located on the towers, creating steam that drives power generators. The first of its kind, it is estimated that the farm will be able to light up about 140,000 homes a year. Also noticeable in the upper right on the 2014 image is the Silver State Solar Project.
