[Episode #203] – The Case for Climate Optimism

Jul 26 2023

Mini Episode

Why does so much media coverage of climate change emphasize the worst-case scenarios and the slow speed of the energy transition? Why don't more stories highlight how the energy transition is working and accelerating, reducing expected increases in carbon emissions and rendering the worst-case warming scenarios increasingly unlikely?

These are important questions, because reporting about the climate and the energy transition can be a self-fulfilling prophecy. If the media constantly asserts that climate change is unstoppable and that we’re doomed, people will feel discouraged and give up during a critical time in which we must make progress. Whereas by showing people how they can be part of the solution, they will do what they can and support leaders committed to addressing the problem.

It’s also important that we understand what’s real and likely, and what isn’t. An unfortunate number of stories about climate change have emphasized vague “tipping points” and “feedback loops” that might accelerate warming in the future. But those are unquantified and undefined terms referring to highly uncertain possibilities. Meanwhile, highly probable outcomes that would result from existing climate policies are barely mentioned.

So why is there so much media focus on the worst-case scenarios? A shred of uncertainty isn't a sufficient reason to emphasize the worst case above all else. Wouldn't it make more sense to focus on the likely outcomes of our existing policies?

In this episode, we're joined by a climate researcher and data analyst who finds reason for optimism on climate change. Hannah Ritchie is a Senior Researcher in the Programme for Global Development at the University of Oxford. She is also Deputy Editor and Lead Researcher at the online publication Our World in Data, which brings together the latest data and research on the world's largest problems and makes it accessible for a general audience. Her forthcoming book, Not the End of the World, will be published in January 2024.

In today’s conversation, Hannah explains what converted her from a climate pessimist to an optimist, and shares her insights into why stories of climate doom seem to be more popular. We explore a number of her data analyses that support her optimistic outlook. And we discuss why it’s important to give people hope that we can address the climate challenge successfully—not by merely adopting a pollyannish attitude, but by really looking at the facts, and understanding the progress that we’re actually making.

[Episode #200] – ETS Retrospective

Jun 14 2023

Mini Episode

To mark the milestone of our 200th episode, we’re taking a look back at how the energy transition has progressed since we launched this podcast in 2015. We revisit the “war on coal”, the concept of the “energy transition,” advances in wind and solar power, changing perspectives about the future of natural gas, “baseload” power’s fading role, the astonishingly rapid uptake of EVs, evolving views on nuclear power, and more!

We also take a moment to reflect on the Energy Transition Show over the last seven and a half years, and take stock of what we have learned. We consider how the media landscape has changed for podcasts in general, and why we are feeling more confident than ever about our focus and our business strategy.

And since this landmark episode is presented from our point of view, we’re turning the tables so that Chris is the guest, interviewed by Jeff St. John, one of our favorite energy journalists. Jeff is currently the Director of News and Special Projects at Canary Media, and he has been following and writing about the energy transition for about as long as Chris has, so he also has a broad perspective on how the energy transition has progressed.

So join us for this special retrospective episode with two seasoned energy transition observers!

[Episode #188] – Getting to a 100% Clean Grid

Dec 21 2022

Mini Episode

How much of a role might wind, solar, nuclear, transmission, power plants equipped with carbon capture and sequestration (CCS) technology, or direct air capture of CO2 play on a 100% clean power grid? Which mix of those technologies would provide the cheapest pathways to a clean grid?

And once we have met 90% of the need for grid power with clean generation, what will we need to meet the last 10% of the demand for grid power? Will it be ‘overbuilt’ wind and solar? Dispatchable geothermal, hydropower, and bioenergy generators? Seasonal storage using hydrogen or batteries? Conventional fossil-fueled plants with CO2 capture? Or might it be some mix of flexible demand technologies? Or some or all of the above?

For that matter, how certain can we even be about modeling the possible solutions years or even decades ahead? Are there solutions that might play a large role in the future but that we can’t yet model very well? How confident should we be that whatever the solutions turn out to be, we will end up with not only a grid that is completely free of carbon emissions but also one that is fully reliable?

In this episode, we speak with a senior researcher at the US National Renewable Energy Laboratory (NREL) who has been researching and modeling grid power for many years. In this quite technical discussion, we review two new NREL reports that address these questions and show that producing a 100% clean power grid is not only technically feasible by a variety of pathways but also commercially feasible and ultimately, cheaper than continuing to run the fossil-fueled power grid we have today.

[Episode #187] – Transition in Vermont, Part 2

Dec 7 2022

Mini Episode

This is Part 2 of the first series in a new format we are piloting for the Energy Transition Show. Instead of exploring a particular topic with one guest who has a non-commercial perspective, as most of our shows so far have done, this new format aims to tell the stories about how the energy transition is proceeding in some of the places Chris visits in his travels. Through interviews with multiple local experts, including those who are working in the energy sector, we hope this new format will help to demonstrate how the unique challenges and opportunities in every place will determine its particular path through the energy transition.

We are kicking off this new show format with some stories about Vermont for a simple reason: When it comes to the energy transition, Vermont stands out as a place that punches way above its weight. It has innovated numerous policies and mechanisms to reduce its energy consumption and carbon emissions that have been emulated by other US states. And it continues to serve as a model to the rest of the country for effective energy transition strategies.

You’ll learn more about all of these accomplishments, as well as what makes Vermont such an exemplar in the energy transition, in this two-part miniseries based on interviews with eight local experts.

Part 1 was in Episode #186, in which we discussed the supply side of Vermont’s energy picture. In this second part, we look at the demand side.

Interviews with guests featured in this episode were recorded from October 11-15, 2021.

[Episode #184] – EROI of RE

Oct 26 2022

Mini Episode

Do renewable energy sources generate enough energy ‘profit’ to make them worth continued investment? And is any energy profit large enough to run our modern world, as renewables displace fossil fuels?

Some skeptics of the energy transition have claimed that renewables can’t run our world because the net energy they deliver to society is too low. They make this argument drawing from past data for the Energy Returned on Investment (or EROI) for various fuels, which showed high EROIs for extracting fossil fuels, and low EROIs for very early generations of wind and solar technology. However, the historical EROI literature has been plagued with methodological inconsistencies so how reliable is this legacy data for guiding modern outlooks?

In a new paper we discuss in today’s episode, a group of researchers has cleaned up and rectified recent EROI data so that the various fuels can be compared on an apples-to-apples basis. Their new results paint a very different picture from the old literature.

Not only do renewables have sufficiently high EROIs to power our society, they are much higher than the EROIs of the fossil fuels they are replacing! In fact, these results suggest that only through the energy transition can we maintain a functioning society.

To walk us through this new paper, its lead researcher, Dr. David Murphy, an environmental scientist at St. Lawrence University in New York, returns to the show.

In addition to reviewing the results of this new paper, we’ll also talk about some of the other mistaken arguments that are frequently made against the energy transition, and explain why they are wrong.

[Episode #180] – Transition in Alberta

Aug 31 2022

Full Episode

Alberta is the seat of the Canadian oil & gas industry, as well as a major coal producer, so it has historically struggled to align with the energy transition - focusing more on pipelines than turbines. But Alberta is changing. Now, the province has implemented numerous policies designed to support the transition, installing a significant amount of wind and solar power generation capacity. According to the Alberta Electric System Operator, 14% of the province’s electricity generation in 2020 was from renewable energy sources such as wind, hydro and solar.

In this episode, we are joined by energy expert Dr. Sara Hastings-Simon to discuss the challenges and opportunities for energy transition in Alberta. She is an Assistant Professor in the Department of Physics and Astronomy and School of Public Policy at the University of Calgary in Alberta, Canada, where she directs the Masters of Sustainable Energy Development program. She is an expert in energy, innovation, and climate policy, and her work is focused on understanding how energy and industrial transitions happen within different sectors of the economy, and how policy responses can improve outcomes. She is also the co-host of the Energy vs. Climate podcast, which will run this conversation on their podcast feed as well.

We talk about the recent history of the various efforts to build pipelines and LNG facilities to export more Canadian oil and gas; the outlook for exports of hydropower; the progress of Canada’s coal phase-out; and the potential for expanding renewable generation in the province, including geothermal. Sara also shares her perspective on how Canada’s carbon tax regime has played out.
