[Episode #86] – Is Transition Worth It?

Are investments in energy transition, especially for public dollars in the form of incentives or subsidies, worth it? Do investments in energy efficiency truly pay off, or does efficiency just make energy cheaper because we’re using less of it, encouraging customers to use more of it—a phenomenon known as the rebound effect, the backfire hypothesis, and the Jevons Paradox? Is public support for rooftop solar systems worth it, once we add up all its costs and benefits, or would it be better to support utility-scale solar projects, or something else entirely, like efficiency? Do wind and solar farms, and electric vehicles, always deliver climate benefits, or does it depend on the power mix of the grid to which they’ll be connected? And even if we determine answers to these questions, for how long are those answers valid?

These are all difficult questions, but our guest in this episode has investigated all of them, and she shares her insights at length in this wonky but accessible discussion. If you worry that the rebound effect might mean efficiency isn’t worth it, you definitely need to listen to this one.

[Episode #85] – Foreign Aid for Microgrids

If you wanted to build a standalone microgrid in Africa, powered by local renewable resources, and make it reliable enough to run a neonatal intensive care clinic, how would you do it? Work through a development bank like the World Bank to get funding? Work with the government in the host country to manage the funds and the project? Build it around lithium-ion batteries? Use Western contractors to do the installation?

In this episode, we learn how Michael Liebreich, the founder of Bloomberg New Energy Finance, helped create a successful project in Sierra Leone by doing none of those things. His experience is full of useful and surprising lessons, and offers a very interesting model for other aspiring renewable microgrid project developers. We’ll also talk with him about his insights on energy transition as one of its veterans, including his experience in trying to transition London to use more electric transportation, as well as his views on career direction and diversity in the energy industry.

[Episode #84] – Designing Climate Solutions

If you wanted to design a set of policies that would reduce greenhouse gas emissions worldwide, right now, where would you start? How would you figure out which sectors of the economy to target in order to have the maximum impact? Which policies would you choose? How would you go about designing them?

And which sectors of the economy would you target in order to reduce emissions the most? Transportation, maybe? Improving the efficiency of our buildings? Would you believe those two sectors rank at the very bottom of the list?

In this episode, we interview one of the authors of a new book by Energy Innovation titled Designing Climate Solutions, which is like a how-to manual for climate policy, identifying the major sectors of the economy that we should target to eliminate as much greenhouse gas as quickly as possible, and the specific policies that can achieve those reductions. We guarantee you will find some surprises in this one!

[Episode #80] – Building Infrastructure as a Service

If you owned a building, or a long-term lease on a commercial space, would you rather shop for your own building infrastructure—things like HVAC systems—or would you rather buy it as a subscription service from a trusted utility or power provider? Our guest in this episode offers the latter, and it’s an intriguing model for how we might upgrade the equipment for commercial and industrial buildings. There are reasons why 68% of the HVAC equipment in commercial buildings in the US is nearly three decades old and in need of replacement, and those reasons are about the cost, complexity, and difficulty involved in that kind of procurement. Wouldn’t it be better if you could call up your local utility and ask them to upgrade your equipment, using their network of trusted and reputable equipment experts and installers, and then just paid them a small amount for the use of that equipment every month, rather than having to pay thousands of dollars for it up front and taking all of the performance risk upon yourself? From high-efficiency lighting, to HVAC controls and sensors, to other energy-consuming building equipment, Sparkfund offers a subscription approach to procurement backed by a no-risk guarantee, which could unlock a huge opportunity to improve the efficiency of our commercial and industrial building systems more quickly than we do under the status quo.

[Duke Energy Week extra #3] – Storage Potential, the Role of EVs, and Data Analytics

This is a special, free episode of the Energy Transition Show with Chris Nelder, recorded on November 9, 2017, live from Duke Energy Week at Duke University.

In this interview with the Managing Director of the Energy Data Analytics Lab at the Duke University Energy Initiative, we discuss how various storage technologies offer different kinds of services to the grid, and how they should be captured and valued. Could CSP make a comeback? What might the arrival of EVs and the rapid evolution of their batteries mean for the future of the grid? And how can technologies like machine learning and data analytics help accelerate energy transition?

Thanks! 

Thanks to Duke University for making this live taping of the Energy Transition Show possible, and to Leah Louis-Prescott, Elihu Dietz, and the rest of the awesome Nicholas School Energy Club for making it all happen and making us feel welcome and appreciated! You're a class act and you put on a great event.

[Episode #58] – Solar with Storage

Full Episode

Historically, thermal concentrating solar plants were the only type of solar power equipped with storage. But as cheaper PV systems became dominant, thermal solar plants fell into disfavor. Now solar PV systems are beginning to integrate storage based on lithium-ion batteries, and this storage isn't just used to supply power when the sun is down; it is providing grid stabilization services too, which only adds complexity to an already-complicated picture for the future of storage - confounding attempts to model how much storage we’ll need, and of what kind, and when will we need it. Is a large amount of seasonal storage required on a high-RE grid, as some analysts have suggested? Or will other technologies reduce the amount of storage we’ll need? And can we even forecast that need, years or decades in advance? We’ll delve into all those questions and more in this deep dive into combined solar and storage systems.

[Episode #38] – Getting from Here to There

There’s nothing to give you a little perspective on what’s happening on planet Earth like getting off it and seeing its beauty—and it’s human-caused destruction—from space. In this wide-ranging interview, former astronaut Jay Apt, a professor of technology and business at Carnegie Mellon University, shares some insights from his voluminous body of research on energy transition topics, including: what the power grid of the future could look like; how we’ll balance it with increasing levels of renewable energy; how to smooth out the fluctuations in wind farm power output; utility business model evolution and resource adequacy planning; what the optimal amount of storage on the PJM Interconnection might be; the economics of behind-the-meter battery systems; the potential future for EVs providing services to the grid; whether carbon capture and sequestration technology and geoengineering can play significant roles in addressing climate change; the new era of electricity de- and re-regulation; and of course, what it’s like to look down on Earth from space. You’ll never see an hour go by as quickly as this one.

[eLab Extra #6] – Building EV Charging Infrastructure

Full Episode

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

Should utilities be allowed to own EV charging infrastructure, or should that be reserved for private charging companies? How many Level 3 high-voltage chargers do we need at workplaces and shopping areas? And how do we build charging infrastructure now that won’t become stranded assets if and when we transition to fleets of autonomous vehicles? We interview Jonathan Levy of Vision Ridge Partners at RMI’s eLab Summit 2016 to find out.

[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.
