Can Transportation Reach Zero Emissions By 2050?

The electricity sector in the U.S. is nearing a tipping point for clean energy. But transportation isn't seeing the same level of change. In this week's podcast -- recorded live at the Department of Transportation -- we'll look at where the tipping points may occur in electric vehicles, car sharing, public transport and freight. The Energy Gang is produced by Greentechmedia.com. The show features weekly discussion between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Editor Stephen Lacey.
