Petroleum is the life blood of modern society.  It is inexpensive, refueling is easy and it has a high energy density thereby enabling easy ground, rail and air transportation.  Yet climate change and economic and energy security are forcing us to explore alternative methods of transportation to those we currently employ and the means by which we power them.  What are the implications of these changes for our economy and society?  Join the MIT Enterprise Forum’s Energy SIG for a panel discussion on the future of transportation technology, policy and its effects on society.
