Few issues loom as ominously over our future as energy use. In this lecture, Shirley Ann Jackson, president of Rensselaer Polytechnic Institute, argues that we cannot meet tomorrow’s energy security needs by relying on our present, rapidly aging science and technology workforce. The need to replenish the nation's inventory of ingenuity, she says, has become a "quiet crisis." It can only be addressed by identifying and developing new, home-grown science and engineering talent from all sectors of our society. If that effort does not begin vigorously and soon, she contents, the United States will fall behind other countries for the first time since World War II. That would be a catastrophe, because, in Dr. Jackson's view, the search for new energy solutions is "the space race of this millennium." From the Series:Frontier
