[Episode #105] – Can Competition Decarbonize Electricity?

Oct 2 2019

Mini Episode

In this third part of a trilogy of shows about how to decarbonize grid power, former utility regulator Travis Kavulla offers his thoughts on how wholesale electricity markets can use competition to deliver clean electricity. Following our discussion about reforming wholesale markets in Episode #90, and our exploration of how state policies can directly choose clean power in Episode #97, Travis offers some deep thoughts on the respective roles of FERC and state regulators, proposed reforms to PURPA, FERC’s showdown with PJM, the politicization of FERC, the recent battle in Ohio over HB6 (bailing out its nukes and coal plants), and other regulatory battles du jour. So much power market wonkery in such a small package!

[Episode #102] – Transition as Wildfire Adaptation in California

Aug 21 2019

Mini Episode

California’s largest utility is bankrupt as a result of its liability for starting some of California’s largest and deadliest wildfires. Now the utility, its shareholders and investors, and the state itself are trying to figure out how to reorganize the company, manage its wildfire risk, and the pay for its future liabilities in an era of a warming climate and enduring droughts. But that’s just where this story starts, not where it ends. In reality, all of the state’s utilities need a backstop for their wildfire liabilities, and de-energizing transmission lines isn’t the only solution. In fact, these questions go beyond the borders of a single state, and touch on a host of deeper issues, including insurance underwriting rules, building and planning and zoning rules, and even how the grid itself will be operated. And it turns out that many of the same solutions that help us in the energy transition can also help us mitigate the risks of wildfires, and adapt to our new climate reality. We are fortunate to have Michael Wara as our guest in this episode—a bona fide expert on the subject who is a member of the state-appointed wildfire commission in California—to help us think through this complex web of issues and understand how to start plotting a new path into the future.

[Episode #100] – Teaching Energy Transition

Jul 24 2019

Full Episode

For our 100th episode, we thought we’d do a little something special: Interview professors from four US universities who are using the Energy Transition Show as coursework, and make the full show available to everyone, including non-subscribers. We ask these teachers about the specific topics they’re teaching, how they’re using the show in their classes, what concepts students find difficult, what misconceptions students have about energy, and how students are reacting to having study materials in podcast form. We also talk with two of the professors about their new energy transition textbooks, which are being published this year.

[Episode #99] – Metals Supply in Energy Transition

Jul 10 2019

Mini Episode

Is the supply of certain key metals—like lithium, copper, nickel, and cobalt—and “rare earth” metals—like vanadium and indium—potentially a limiter on the progress of energy transition? Or is there enough of them to realize our ambitions? Are they being produced in a sustainable way? How will the geographic concentration of these metals affect geopolitics and trade as the energy transition progresses? How confident can we be about our assessments of their abundance? And how confident can we be about how much of them we’ll need in the future, given the rapid evolution of many of these technologies, and the many alternate ways of producing them?

Our guest in this episode brings all of these questions into a whole new focus, and shows why these questions can’t be answered with some back-of-the-envelope calculation. Instead of asking whether there is enough of these metals in the Earth’s crust, he says, or about how they are mined, we should be asking much more sophisticated questions about the chemical industry, the opaque, illiquid markets in which these metals are traded, and the geopolitical implications of their trade.

[Episode #98] – Why Building Transmission is So Hard

Jun 26 2019

Mini Episode

Building high voltage transmission lines has never been easy, but now it’s arguably both harder than ever, and more necessary than ever, as we seek to unlock the vast potential of wind and solar in the US and ship it to major population centers. But it’s not a business for the faint of heart, as we’ll hear in this incredible story by award-winning investigative reporter and author Russell Gold of the Wall Street Journal. His new book, Superpower, chronicles the story of Michael Skelly, a developer who spent a decade and a great deal of money trying to build five major transmission lines in the US to support the burgeoning wind industry, only to be undermined, deceived, shot down, and ultimately driven to giving up, by people who opposed the lines for their own selfish interests. It’s an amazing story and a great cautionary tale for any prospective transmission line developer, as well as a wellspring of crucial insights that will benefit all who work in energy transition.

[Episode #97] – How State Policies Can Drive Decarbonization

Jun 12 2019

Mini Episode

As we continue looking for ways to decarbonize our energy systems, we often have to decide whether it’s better to try reworking our market rules so that the markets will do a better job of procuring clean energy, as we discussed in Episode #90, or whether it makes sense to just mandate the procurement of clean energy resources. The former is a job for the Federal Energy Regulatory Commission (FERC), but the latter is the domain of the states. In fact, our guest in this episode, a senior attorney with NRDC and the Sustainable FERC Project, argues that because states are really the only ones with the authority to regulate energy in order to obtain a more environmentally beneficial outcome and combat climate change, their mandates are a necessary pathway to decarbonizing the grid. And that, to some extent, market price distortion is in the mind of the beholder.

[Episode #95] – Powering the world with RE

May 15 2019

Mini Episode

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 #94] – Integrated Decentralized Power Systems

May 1 2019

Mini Episode

As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like. What if millions of distributed resources become the dominant resources, and the grid assumes a subordinate role as a residual supplier of energy? What if the control of the system is also decentralized, through the actions of millions of devices? What if the roles of transmission system operators and the distribution system are diminished as their responsibilities are distributed across all those devices? And how will utilities, power market operators, regulators, legislators, and local officials deal with a radical shift in their roles and responsibilities? These are the questions that our guest in this episode—an 18-year veteran of wholesale power market design at the California ISO—thinks about, and he shares those deep thoughts with us in this wonky yet heady discussion.

[Episode #93] – Energy Transition in India and Southeast Asia, Part 2

Apr 17 2019

Mini Episode

This is Part 2 of our two-and-a-half hour interview with Tim Buckley, of the Institute of Energy Economics and Financial Analysis, based in Australia. We featured Part 1 in Episode 91, in which we primarily discussed the future of coal fired power in India. In this second part, we expand on the India story and look more broadly at energy transition across Southeast Asia, and consider the outlook for coal, renewables, and nuclear power in China, Japan, Bangladesh, Pakistan, and Malaysia, among others. As he did in Part 1, Tim shares with us in this episode a fascinating set of data on the future of energy in Southeast Asia that is oftentimes at sharp variance with the projections that we hear from energy watchdogs like the International Energy Agency. Tim tells a much more hopeful story about energy transition in the developing world. For example: If you think that China’s building more coal plants means that its coal consumption is going to go up, think again! Energy transition is moving ahead, and will move ahead, much more quickly in Southeast Asia than any of our major agencies project, and that is great news for the climate.

[Episode #92] – Financing Coal Plant Retirements

Apr 3 2019

Mini Episode

The coal power sector in the US is continuing to shrink due to poor economics, but this doesn’t mean we’re retiring coal fired power plants quickly enough to reduce carbon emissions at a rate that achieves our climate goals. So what’s the best way to get rid of coal plants before they reach the end of their expected lifespans, particularly while the Trump administration and the Republican party continue trying to find ways to keep coal plants open? Democratic state Representative Chris Hansen of Colorado has proposed a solution: Refinancing the debt that utilities still owe on their coal-fired plants with cheaper, public bonds, and then shutting down the plants. It’s an idea that would retire coal plants and reduce carbon emissions, save utility customers money, create better investment opportunities for the utilities, and replace that power with cheaper, clean, solar and wind power. Everybody wins! It’s a powerful idea whose time may have come in Colorado, where fossil fuels still make up 78% of the state’s electricity mix, and major utilities in the state, like Xcel Energy, have declared their intention to transition to 100% clean power in the coming decades. Will Hansen’s bill have the right approach to help achieve those goals? We dive into all the important details in this episode and find out!
