Reiner Kuhr worked in the electric power sector for more than 40 years and is the co-founder of the Center for Academic Collaboration Initiatives, a group that aims to increase the exchange of research among students and academic institutions. In his second appearance on the podcast (his first was on May 27, 2021) Kuhr  talks about his recent paper on the problems and costs associated with integrating renewables into electric grids, why batteries are an expensive way to reduce emissions, and why you can “go nuclear, or go renewable, but you can’t do both.” (Recorded October 19, 2022.)
