The American energy system is in transition away from coal and toward less carbon intensive fuels, such as natural gas and wind. Energy produced by renewables and gas is projected to grow by 10 quadrillion BTUs over the next two decades, while other sources will remain constant or decline. Such a rapid transition requires construction of new facilities for generating and transmitting energy. Stephen Ansolabehere, Professor of Government at Harvard, tells the story of recent energy development efforts across the United States and the lessons for the transition toward a less carbon intensive energy system.
