The Spain-based company, Abengoa Solar, claims to be “a global leader in solar thermal energy.” Its website boasts: “Abengoa Solar is the largest solar plant operator worldwide.” Abengoa went public in October 2013, and since, its stock price has doubled. With the support the White House gives to solar energy and the mandates for renewable energy present in the majority of states, Abengoa sounds like a solid investment. And, that’s the image Abengoa has burnished with full-page ads in the Wall Street Journal to encourage investment. However, rather than a “buy,” Abengoa should be a “sell”—sell quickly—as its American run could be coming to a close.
