[Episode #37] – Corporate Buyers of Renewables

Full Episode

Although it’s not widely talked about, one of the hottest sectors buying renewables now is the corporate sector. Fortune 500 companies are buying solar and wind power, and renewable energy credits, at a record pace. But why? What’s in it for them? What are the economic risks and rewards of going to the extra trouble to buy green power? How do arrangements like “virtual power purchase agreements” work? How do we manage balancing between wholesale markets in a future of strong interstate corporate procurement? And what’s the outlook for corporate buying of renewables? Our guest answers all of these questions and more in this wonkilicious episode, guaranteed to keep CFOs on the edge of their seats.

[Episode #35] – Green Bonds

What are green bonds, and how can they help mobilize private capital to fund energy transition and climate change mitigation measures? What kinds of things can green bonds be used to fund? What are the various roles for private, corporate, and sovereign issuers? Why does the green bond market need to grow by roughly 10x over the next few years to $1 trillion a year globally, and is there even enough capital out there willing to accept single-digit returns to buy that amount of green bonds? Are green bonds an answer to the stranded assets problem in the fossil fuel sector? And what can the appetite for green bonds tell us about monetary policy and appropriate discount rates for climate change mitigation measures? We get deep into all of these questions with the CEO of the Climate Bonds Initiative, an international NGO working to mobilize debt capital markets for climate solutions.

[eLab Extra #5] – EVs and More in Austin, TX

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

Through a variety of programs, Austin Energy, the eighth largest publicly-owned electric utility in the U.S., has led the way to an EV future in Texas, installing the first EV charging infrastructure in the region, offering rebates for installing charging stations and the ability to charge up at 250 charging stations throughout the city for a low flat rate using 100% renewable energy. Karl Popham, the Electric Vehicle & Emerging Technologies Manager at Austin Energy, explains how he did it and what other similarly positioned utility leaders can do in an interview from RMI’s eLab Annual Summit 2016.

[eLab Extra #3] – Grid Modernization and DERPs

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

Grid architecture is evolving, with loads becoming increasingly indistinguishable from generators, and local generators and other distributed resources increasingly supplying the services that were always provided by large central generators in the past. Meanwhile, an ever-evolving set of regulations for wholesale market operations is both enabling new market participants and challenging the security of old market participants. Lorenzo Kristov of the California Independent System Operator returns to the Energy Transition Show to share more of his view of the future in an interview from RMI’s eLab Annual Summit 2016.

[eLab Extra #2] – Hawaii’s Energy Transition

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

How is Hawaii managing one of the most rapid energy transitions in history to variable wind and solar generators, while maintaining a balanced, isolated grid and actually reducing long-term costs? It’s no accident: They have developed a transition roadmap and they are working hard to adopt the latest technology while preserving social equity…not just for grid power, but for electric vehicles as well, toward a goal of reaching 100% renewable electricity by 2045. Lorraine Akiba of the Hawaii PUC shares her perspective in an interview from RMI’s eLab Annual Summit 2016.

[Episode #32] – Resources and Economy

Full Episode

The notion of “decoupling” energy consumption from economic growth has become vogue in policy circles, but how much evidence is there that it’s really happening? If the energy intensity of our economy is falling, are we sure that it’s becoming more efficient, or might we just be offshoring energy-intensive industries to somewhere else…along with those emissions? If energy reaches a certain percentage of total spending, does it tip an economy into recession? Is there a necessary relationship between energy consumption and monetary policy? Is there a point at which the simple fact that we live on a finite planet must limit economic growth, or can economic growth continue well beyond our resource consumption? Can the declining EROI of fossil fuels tell us anything about the future of the economy? And can we have economic growth using clean, low-carbon fuels, or might transitioning to an economy that produces zero net new carbon emissions put the economy into recession and debt?

To help us answer these thorny questions, we turn to an expert researcher who has looked at the relationship between energy consumption and the economy over long periods of time and multiple economies, and found some startling results with implications for the Federal Reserve, for economic policymakers, and for all those who are involved in energy transition.

[Episode #29] – Grid Simulation and Wind Potential

Full Episode

What combination of power generators on the U.S. grid produces reliable power at the lowest cost? Or, what’s the most renewable energy that can be deployed at a given grid power cost, and what kind of transmission capacity is needed to support it? How would the U.S. grid be different if it were one, unified grid with more high-voltage direct current (HVDC) transmission capacity? What’s the most productive design for a wind farm? How might weather and a changing climate affect future electricity production from wind and solar farms? And how much renewable power is really feasible on the U.S. grid?

These have been devilishly difficult questions to answer, but now advanced mathematical simulations are beginning to make it possible to answer them much more quickly…and if quantum computing becomes a reality, we could answer them instantly.

In an homage to Comedy Central’s Drunk History, this episode features a conversation conducted over several pints of IPA with a mathematician who recently developed such a simulator while he was working at NOAA (the National Oceanic and Atmospheric Administration) in Boulder, CO. His insights on how the grid of the future might actually function are fascinating, and will likely shatter some of your pre-existing beliefs. It also contains a few nuggets for the serious math geeks out there.

[Episode #27] – Better Grid Modeling

Full Episode

Although it’s clear enough that energy transition is necessary and reasonable, and although we know that transition is mainly happening on the grid at first, there is still much uncertainty about exactly where on the grid different strategies can be tried, how much they can accomplish, and what they’ll cost, relative to the alternatives….not to mention how the rest of the grid will respond as different measures—like storage, demand response, rooftop solar, controlled dispatch, and so on—are implemented. What’s needed to answer all these difficult questions? Better models, including serious math, by serious researchers.

Fortunately, one of those researchers is willing and able to explain several years of her work in grid modeling at NREL and elsewhere. So tune in and put on your thinking caps, because this episode (Geek Rating 10!) is not for the faint of heart.

[Episode #24] – Starting Over

Full Episode

What if we didn’t have to work around the grid we have today, with all of its inertia and incumbents and inflexibility? If we could start over and design the grid from scratch, what would it look like? And once we understood that, how might it change the way we are going about energy transition now, in order to reach that goal more quickly and directly? If what we really want is a grid that is fair, equitable, reliable, efficient, resilient, sustainable, and which serves our climate and social goals, what are the first principles we might work from, and what mechanisms might get us where we want to go? This freewheeling conversation aims to help all of us “think outside the box” a bit more, and imagine what the possibilities might be if we could just start over.

[Episode #23] – Facts and Falsehoods in Energy Transition

Full Episode

Should we tweak our markets to keep nuclear plants alive, or forget about markets and pay for them another way… and do we really need them at all to keep the grid functioning? Is nuclear power really declining because of overzealous environmentalists, or are there other reasons? Is it possible to balance a grid with a high amount of variable renewables and no traditional baseload plants? Is cost-benefit analysis the right way to approach energy transition? How much “decoupling” can we do between the economy and energy consumption, and how can we correctly measure it? Why are we so bad at forecasting energy and economic growth, and how can we do it better? How will energy transition affect the economy?

We explore all of these questions and more, and try to separate fact from falsehoods in this wide-ranging interview. It might even change your mind about a few things.
