In this episode of The Hidden Joule podcast, we discuss with Dr. Charles A. S. Hall the concept of Energy Return on Energy Invested or EROI and its role within a BioPhysical Economic Framework and the ESG movement. We consider unrestrained growth and the Laws of Thermodynamics and the application within Sustainability/ESG, Neo Classical Economics and Neo Liberalism, as well as renewable solutions. Lastly, we dive into the role and link between energy and wealth, and the differences between Physical Sciences and Social Sciences.
