[Episode #75] – Transportation Transition

Vehicle electrification is gaining real momentum in 2018, from light duty passenger vehicles, to medium and heavy duty vehicles, port equipment, and even ferries. But this rapid transition in transportation isn’t without its risks, its critics, and its incumbent opposition. Will EVs take over the personal vehicle market, and if so, how quickly? How much of a role will ridesharing services play in the future? What’s the future of autonomous vehicles? How will the future of personal vehicle ownership look? Is there going to be enough supply of rare earth metals to support the EV revolution? Are lithium ion batteries going to become an environmental hazard or will we recycle them?  Are EVs cleaner than high-efficiency gasoline vehicles on a lifecycle basis? Will EVs or robotaxis increase the vehicle miles traveled, and if so, what will be the net effect on emissions in that scenario? How should we be planning to accommodate the loads of EV charging on the power grid? And what about the loads of the medium- and heavy-duty sectors? Can drivers and bicyclists and robotaxis learn to share the road? And what would a transition-friendly transportation infrastructure look like?

Our guest in this episode has researched all of these questions, and shares with us the best available knowledge on the rapidly evolving sector of new mobility. Costa Samaras is an associate professor in the Department of Civil and Environmental Engineering at Carnegie Mellon University who has published numerous studies related to new mobility and the effect of EVs on emissions and on the power grid.
