"NIPTON, Calif. — The Ivanpah solar power plant stretches over more than five square miles of the Mojave Desert. Almost 350,000 mirrors the size of garage doors tilt toward the sun with an ability to energize 140,000 homes. The plant, which took almost four years and thousands of workers assembling millions of parts to complete, officially opened on Thursday, the first electric generator of its kind. It could also be the last."
"Since the project began, the price of rival technologies has plummeted, incentives have begun to disappear and the appetite among investors for mammoth solar farms has waned. Although several large, new projects have been coming online in recent months — many in the last quarter of 2013 — experts say fewer are beginning construction and not all of those under development will be completed."
