[Episode #52] – 2-Year Anniversary – Destination Unknown

It’s the two-year anniversary of the Energy Transition Show, so we thought we’d take a break from the deep dives and just have a little fun skiing around on the surface for a change. Dr. Jonathan Koomey returns to the show for a freewheeling discussion about some of the interesting questions and debates swirling around the energy transition today, and hopefully help us glue together many of the themes that have emerged from our first 51 shows.

How do you go about an energy revolution? Is 100% renewables the right goal? How much seasonal storage will a high-renewables grid need? What will it cost? Is there a future for nuclear power? Or CCS? What should get the credit for declining U.S. emissions?  How do we model the best pathways to a future of clean and sustainable energy? Can the IPCC modeling framework be fixed? What kind of carbon mitigation pathways should we be projecting? And how should we communicate the important messages on climate and energy transition? We tackle all these questions in one big omnibus episode.

Following the interview, Chris shares some of his reflections on Hurricane Harvey in an extended postscript, which we’ve made available in the free, abridged version as well as the full, subscriber version of this show.

[Episode #46] – Is 100% Renewables Realistic?

[This episode has been released ahead of schedule to coincide with the publication of the paper it covers. Enjoy! --Ed.]

Is it really feasible to run the world on 100% renewables, including supply and demand matching at all times and places? Would doing so require vast amounts of seasonal storage? Are exotic new technologies like next-generation flexible nuclear power plants or coal plants equipped with carbon capture and storage (CCS) equipment needed to balance out variable renewables at a reasonable cost?

In this episode, Dr. Christopher Clack offers a very detailed, deep critique of the 100% wind, water and solar model proposed by Stanford’s Mark Jacobson in 2015, and explains where the model falls short. We also discuss a recent paper by Jesse Jenkins from MIT and Samuel Thernstrom from the Energy Innovation Reform Project, which reviewed some recent papers on what “deep decarbonization” might imply for our future energy mix. This 90-minute, super-wonky chat over a few pints of IPA is guaranteed to leave you reeling…and hopefully, more informed about the best policy pathways to a mostly renewable future.

[Episode #44] – Different Strokes

One thing is sure about energy transition: There is no one-size-fits-all approach. As our previous episodes on individual countries showed, there are different opportunities and challenges in each place…even each US state has to find its own unique transition path. In this episode, we have a wide-ranging talk with Dr. Benjamin Sovacool of the University of Sussex about a tiny fraction of his voluminous research on energy transition topics, with a focus on the speed of energy transitions, the ways that the Nordic countries of Denmark, Finland, Sweden, Norway and Iceland are going about their transitions; his outlook for CCS technology and nuclear power; the potentials and pitfalls of nuclear power and the potential for distributed energy resources to displace nuclear; and we’ll surprise him with the first-ever Energy Transition Show lightning round, in which he’ll answer 15 key questions about energy transition (which were the subject of one of his books) in under two minutes!

[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.

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

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.
