[Episode #127] – Hard-to-Decarbonize Sectors

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.

[Episode #123] – Sustainable Energy Transitions

Addressing the threat of climate change means executing a successful energy transition. But as the transition proceeds, we are increasingly having to confront the impacts of transition technologies, and consider the trade-offs of choosing those technologies over the conventional technologies that they are displacing - because nothing we can do is without an impact of some kind, and everything we build requires the use of raw materials. So the question of what is truly sustainable is beginning to take a larger importance in the formation of policies designed to advance energy transition.

But energy is still being taught primarily as part of the engineering discipline, leaving students from non-engineering disciplines in need of ways to learn something about energy, in order to help them be more effective in their work. Fortunately, professor Dustin Mulvaney of San Jose State University in California has a new textbook designed to address this need, titled “Sustainable Energy Strategies: Socio-Ecological Dimensions of Decarbonization.” It’s a very ambitious effort to survey many of the complex topics that are critical for people involved in energy transition to understand. In this episode, we talk with Dustin about why he wrote it, and we take a walk through each chapter in the book to understand the complex questions around what “sustainability” really means in the context of energy transition.

[Episode #84] – Designing Climate Solutions

If you wanted to design a set of policies that would reduce greenhouse gas emissions worldwide, right now, where would you start? How would you figure out which sectors of the economy to target in order to have the maximum impact? Which policies would you choose? How would you go about designing them?

And which sectors of the economy would you target in order to reduce emissions the most? Transportation, maybe? Improving the efficiency of our buildings? Would you believe those two sectors rank at the very bottom of the list?

In this episode, we interview one of the authors of a new book by Energy Innovation titled Designing Climate Solutions, which is like a how-to manual for climate policy, identifying the major sectors of the economy that we should target to eliminate as much greenhouse gas as quickly as possible, and the specific policies that can achieve those reductions. We guarantee you will find some surprises in this one!
