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

Jan 4 2017

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

Dec 14 2016

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

Nov 2 2016

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

Oct 5 2016

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

Aug 24 2016

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

Aug 10 2016

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.

[Episode #22] – Can Economics Guide the Energy Transition?

Jul 27 2016

Full Episode

Is conventional, free-market economic theory really up to the task of energy transition and combating climate change? Can we let the so-called invisible hand of the market guide us through the troubled waters ahead, or will we need firm policy direction and deliberate, top-down planning to secure the best outcomes? How useful can free markets be, in transitioning us away from coal, and meeting our climate targets and securing enough carbon-free power to run our societies? Will they be any help at all in supporting technologies like carbon capture and sequestration, or geoengineering? Can negative discount rates help us pay for climate change mitigation projects? And what does the future hold for oil? We discuss all of these questions and more with veteran energy editor Ed Crooks of the Financial Times.

[Episode #21] – The Role of Development Banks in Energy Transition

Jul 13 2016

Full Episode

Multilateral Development Banks (MDBs) like the World Bank, the African Development Bank and the Asian Development Bank are publicly committed to ending energy poverty and enabling energy access to the developing world. But their conventional processes and approaches to risk management make it difficult for them to invest in the decentralized renewable energy solutions that have the best chance of lifting people out of energy poverty. So what can be done about it? To find out, we talk with a pioneer in the energy investment and energy access space and ask her some pointed questions about how development bank funding works, and how it needs to be changed.

[Episode #20] – Grid Evolution

Jun 29 2016

Full Episode

Utilities face a host of rapid changes in a what used to be a staid business: new business models, changing supply and demand forecasts, new distributed architectures, new types of resources, new participants in the power grid that they don't control…yet they still must maintain a highly reliable power grid that operates within fairly narrow parameters.

Meanwhile, difficult questions remain to be solved, about how we’re going to manage our grid power transition, who the winners and losers will be, what destination we’re headed for, what role consumers and “prosumers” will play in the future, and what our reasons are for executing transition the way we do.

We tackle all of these issues in this wide-ranging, very geeky conversation about the “blocks and squiggles” of the grid of the future. Grid power transition, the rebound effect, energy efficiency, utility business models, cutting-edge grid power management considerations, regulation and rate design, electric vehicles as distributed energy resources… they’re all here.

[Episode #19] – Distributed Renewables in Latin America and Beyond

Jun 15 2016

Full Episode

Finance geeks, this episode is for you! Latin America has had one of the fastest-growing renewable energy markets on the planet for the past several years, but nobody ever talks about it. We aim to correct that in this wide-ranging interview with Adam James, Deputy Director of Global Strategy and Policy with SolarCity.  Who’s got the hottest auction design? Who’s growing at eye-popping rates?  Who screwed up their incentive program so badly that nobody wants to invest there anymore? And what are some outside-the-box ideas about how to get capital flowing into distributed energy systems in the developing world? Plus: oblique Prince references! (RIP)
