[Episode #172] – IPCC AR6 Part 1

The IPCC published the final part of its Sixth Assessment (“AR6”), the Working Group III report, on April 4, 2022. The IPCC's Working Group III report contains assessments of how the energy transition can reduce emissions in the context of an updated outlook for global warming. Together, the three reports of AR6 comprise over 6,000 pages of material, so we have chosen to focus our coverage on the Working Group III report, which we present in two episodes.

In this first episode on AR6, we speak with one of the lead authors of the Working Group III report, energy researcher Benjamin Sovacool of the University of Sussex. We discuss some major advances in AR6 over the AR5 report of eight years ago; the gaps between our national climate action ambitions, what is really needed to limit warming to 1.5 or 2°C, and some ways that those gaps can be closed; how market-based financial approaches can be harnessed to reduce carbon; the importance of equity and “just transition” strategies; the challenge of path dependency and technology lock-in; how political economy can inhibit taking action on climate; the roles that non-government actors and individuals can play in the transition; and the various ways of decarbonizing transportation and providing better low-carbon mobility.

Our second episode on AR6, Episode #173, will review the updated figures for the remaining carbon budget, and consider the pathways and probabilities for limiting warming to 1.5 and 2°C.

[Episode #103] – A Return to Regionalism

Is “peak oil” still something to be concerned about, and if so, what does depletion of conventional oil supply suggest about our future? Our guest in this episode certainly thinks peak oil will be a key factor in the decades ahead, and he foresees a future in which humanity must downsize significantly, both in total population and in the energy intensity of our lifestyles. He believes we’ll have no choice but to return to a more regionally focused way of life, depending on local resources, and doing a lot less travel and shipping. As one of the co-founders of the Association for the Study of Peak Oil, Colin Campbell’s view on the importance of oil to the global economy, and his vision of geological limits leading to declining oil production, has never wavered. And as a petroleum geologist with four decades of experience in finding and producing oil, including performing some of the first experiments with fracking, his knowledge of oil geology is unparalleled. His cautionary perspective serves to highlight the urgency of energy transition, because there are more reasons we need it to succeed in addition to eliminating carbon emissions, otherwise, oil scarcity may yet become a key factor in determining what our futures hold.

[Episode #95] – Powering the world with RE

Can we run the world on renewables alone? Various researchers have tried to model how a given country might run a grid using mostly renewables, oftentimes finding that carbon-negative technologies, advanced nuclear power, and even coal power plants equipped with CCS will be a part of the solution set. But no one has produced a comprehensive model that shows how we can run the world on renewables alone, while accurately modeling the weather and grid conditions at a very discrete scale, at hourly resolution, using data on the renewable resources in each region, and determining how that would work while selecting the least-cost resources… until now.

In this episode we speak with a researcher from Lappeenranta University of Technology in Finland, one of an international team of 14 scientists who have spent the past four and a half years performing research, data analysis, and technical and financial modeling to prove that a global transition to 100% renewable energy is economically competitive with the current fossil and nuclear-based system, and could reduce greenhouse gas emissions in the energy system to zero even before 2050. This first-of-its-kind study outlines how the world could limit warming to 1.5°C with a cost-effective, global, 100% renewable energy system that does not use negative carbon technologies, and provides all the energy needed for electricity, heat, transport and desalination by 2050.

[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!

[Episode #28] – Transition in Cities

Full Episode

It is widely assumed that the ongoing migration of rural peoples to mega-cities all over the world will help reduce humanity’s per-capita energy footprint, while giving people a higher standard of living and accelerating energy transition. But the world is full of old, inefficient cities in desperate need of an eco-makeover, and of experts who understand the principles of “smart urbanization” and who can help identify how to transform a city from brown and dumb to smart and green. What’s the potential for replacing concrete with living things in cities? How can autonomous and electric vehicles help make cities cleaner and more livable? Why isn’t China promoting its phenomenal success with e-bikes to the rest of the world? Is China’s commodity demand going to continue to weaken as it moves away from a manufacturing economy? And will the emissions it was generating just move elsewhere when it does? All these questions and more are answered in this wide-ranging conversation with an expert on smart urbanization and China.
