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.
