In its just-released annual report on global clean energy investment, the Pew Charitable Trusts finds an 11 percent drop in investments in 2013. What contributed to the global decline, and what are the expectations for activity in the clean energy sector moving forward? During today's OnPoint, Phyllis Cuttino, director of Pew's Clean Energy Program, discusses the impact of policy uncertainty in the United States and Europe. She also weighs in on how the natural gas boom could be affecting clean energy investments. Today's OnPoint will air at 10 a.m. EDT.
