[Episode #201] – India Update Part 2

Jun 28 2023

Mini Episode

This is part two of our interview with Mohua Mukherjee, a Senior Research Fellow at the Oxford Institute for Energy Studies. Previously, she was a development economist and project manager with the World Bank, working in over 40 countries.

In this second part, we dive into India’s use of oil and natural gas, and why it has continued to purchase these fuels from Russia, even as the West has implemented trade restrictions. We go on to explore India’s unique approach to transitioning mobility to vehicles that run on electricity and CNG. We highlight India's strategy for developing domestic industries in battery manufacturing, solar energy, hydrogen electrolyzers, and other clean technologies. We also take a closer look at India's astonishing progress in expanding electricity access to its vast population. We examine the challenges faced by electricity distribution utilities in the country, and their efforts to enhance efficiency. Finally, we address India's progress on its climate initiatives and the importance of ensuring a "just transition" as the nation reduces its reliance on coal-fired power.

Be sure to check out part one of this interview in Episode #199 for a review of India’s overall energy mix, including a close look at its use of coal, solar, and wind.

[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 #190] – Financing Utility Scale RE in Developing Countries

Jan 25 2023

Mini Episode

Multilateral development banks (MDBs) like the World Bank are increasingly under pressure to invest more in renewable energy projects in emerging markets. The lack of financing for such projects is a problem at the small, distributed scale as we discussed in Episode #189, and it’s also a problem for utility-scale projects as we discuss in this episode.

In this conversation, Brad Handler, a Program Manager and Researcher at the Sustainable Finance Lab of the Payne Institute at the Colorado School of Mines who tracks various such projects and initiatives, walks us through some recent Energy Transition Mechanisms (or ETMs) and Just Energy Transition (or JET) refinancing projects that aim to close coal plants in the developing world long before the end of their expected lifespans, and replace their generation with renewable power. A former Wall Street Equity Research Analyst with 20 years of experience covering the oil sector, Brad has a deep understanding of how finance in the traditional energy sector works, giving him an excellent perspective on how energy transition financing could work. He does a wonderful job of explaining the oftentimes opaque and complex world of sustainable finance so that it’s comprehensible.

Closing coal plants remains the number-one priority globally for reducing carbon emissions. So although these are still very early days for refinancing projects, it’s worthwhile to examine how and where development banks are finally taking some real steps to accelerate the energy transition in emerging economies, derisking the sector and motivating much more conventional private sector capital to participate.

[Episode #189] – Financing the Transition

Jan 4 2023

Mini Episode

According to the International Energy Agency (IEA), almost all of the growth in global clean energy spending is happening in advanced economies and China, while the two-thirds of the global population that live in emerging market and developing economies are receiving less than one-fifth of the total. The reason? The high cost of capital.

But why is the cost of capital so much higher in emerging economies than in advanced economies? Why is it still so much harder and more expensive to finance clean energy projects than it is to finance fossil fuel projects in those countries? And what can be done about it?

In this episode, we speak with a solar project developer working in Costa Rica to try to answer these questions. Building on our previous discussion from Episode #21, we try to explain why so little progress has been made, especially by the multilateral development banks (like the World Bank), in reducing the cost of financing for renewable energy projects in emerging economies. We review the different roles that various financial institutions play in financing the energy transition, and we ask what needs to change to unlock the flow of capital into energy transition solutions (especially distributed solar). We also put the risk and reward of investing in those projects in a fresh context, and call upon banks of all kinds to start acting in more creative and ambitious ways to take bolder action and get capital deployed where it is most needed, and where it can do the most good.

[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 #182] – 7th Anniversary Show

Sep 28 2022

Full Episode

For our Seventh Anniversary show, energy researcher Jonathan Koomey rejoins us to review major stories over the past year, and to take stock of how the energy transition has progressed.

We talk about how the global energy crunch we covered in 2021, in Episode #158, has evolved into a full-fledged global energy crisis in 2022. We reflect on the theme of Episode #181, “Command Capitalism,” and consider the increasing interventions governments are making in energy markets to manage the crisis. We muse on the episodes we did over the past year on the trajectory and speed of the energy transition. We consider the outlook for storage systems, in light of the episodes we did on that subject. We discuss how incumbents have resisted the energy transition, as we covered in our episode on utility corruption, and ask whether incumbents are gaining or losing ground. We review the highlights of our shows on the latest IPCC report and on climate modeling. And Jon shares some of his latest work in energy modeling.

It's a smörgåsbord of energy transition goodness, so strap on a napkin and join us!
