In his book “Power Trip: The Story of Energy,” professor of mechanical engineering at the University of Texas at Austin, Dr. Michael E. Webber describes how the rise of the world’s most successful societies can be told largely through the story of how they managed the energy sources to them. “Power Trip” explores how energy has transformed societies of the past and offers wisdom for today's looming energy crisis. We examine how the history of one kind of power is intrinsically linked with another, in this edition of “Leonard Lopate at Large” on WBAI.
