Professor Penna is general editor with Richard Judd of the University of Maine, Orono of a book series titled, The Environmental History of the Northeast, published by the University of Massachusetts Press. Our definition of the northeast includes the Canadian Maritime Provinces and their coastal waters, New England and its coastal waters, New York, New Jersey and Pennsylvania. Currently, he is writing a global environmental history of energy use covering the last 1000 years with a Pennsylvania State University colleague and environmental historian, Brian Black. Although much of their research will focus on the growth of fossil fuel use during the industrial age, they will be exploring the energy used to produce, transport and consume food in the industrial world. In recent years, he has published two global environmental histories, The Human Footprint: A Global Environmental History and Natural Disasters in a Global Environment with Jennifer Rivers and co-edited with Conrad Wright, Remaking Boston: An Environmental History of the City and Its Surroundings.
