You can't talk about the renewable transition without talking about "net zero."  The concept of achieving net zero is the ultimate intersection of energy and climate policy. Governments, corporations and electric utilities are all promising to eliminate or 'net to zero' their carbon footprints, most of them by about the year 2050.  How did this movement begin?  How do we get there?  In this episode, Mike talks with Paul Simons, a senior fellow at the Jackson School of Global Affairs at Yale University and former Ambassador to Chile.  Join Mike on a journey through Paul's distinguished career at the highest levels of climate and energy policy.
