Video: Expert Discusses Future of Solar Power

Lawrence Kazmerski, Director of the National Center for Photovoltaics, discusses the prospects of solar-photovoltaic (PV) technologies, arguing that this solar-electricity source is at a tipping point in the very complex realm of worldwide energy. Kazmerski discusses how recent research and development advances in areas such as solarcells and the materials used to make them, and concentrators which collect and focus the sun's light onto solar cell arrays, have pushed the technology to the point where the worldwide utilization of PV electricity generation is both technologically and economically feasible.
