The Ivanpah Solar Power Facility in California’s Mojave Desert, once touted as a flagship of U.S. solar energy leadership, is nearing its end.

Launched with $1.6 billion in taxpayer-supported loans in 2011 and praised by former Energy Secretary Ernest Moniz, the massive project spans five square miles, 65 miles southwest of Las Vegas, with three 459-foot towers and 173,500 computer-guided heliostats. Yet, it has devolved into another costly, mismanaged green-energy failure driven by centralized planning.
