When it comes to energy transition solutions, wind and solar and big battery projects regularly make headlines, but we don’t often hear much about the hard-to-decarbonize sectors, like aviation, shipping, trucking, cement manufacturing, and steelmaking. Reducing emissions from these sectors is challenging for a number of reasons, but we must find ways to do it, because they account for about a third of global carbon emissions. And fortunately, there is a great deal of effort now being focused on these sectors, through an array of partnerships between governments, non-governmental organizations, and private industry. In this episode, we speak with the CEO of the Rocky Mountain Institute, a clean energy “think and do tank” founded by energy luminary Amory Lovins which has been working on energy transition for the better part of four decades, about some of the ways that we can decarbonize these sectors.
Energy transition is happening quickly and disruptively in the transportation sector. But it is generally an open question whether the transition currently at hand is producing socially beneficial results. As we grapple with a sudden influx of new modes of mobility and business models, and contemplate the dawning of an entirely new mobility paradigm, are we just letting technology take us wherever it wants to go, or are we guiding technologies toward sustainable mobility? For that matter, what does sustainable mobility even mean? How can we weigh up all the pros and cons of new mobility modes—not just the social effects like safety and equity, but the environmental impacts, the total impact on the energy system, and the socioeconomic strategies we bring to our urban development and civic planning activities more generally? Can we hedge our bets against sudden and massive dislocations produced by autonomous vehicles? We explore all those questions and more in this episode with a researcher from Oxford University who has studied them deeply.
