In this Climate Chat episode, we interview Stanford professor Mark Z. Jacobson about his research that shows we can rapidly transition to 100% renewable energy. This is a controversial position, yet with renewable energy costs dropping rapidly, many parts of the world already generate 100% of their electricity in certain parts of the day from renewables. We will discuss the state of renewables today, the path to 100% renewables, and we will discuss some the issues that naysayers say will prevent us from achieving 100% renewable energy. Mark Z. Jacobson’s career has focused on better understanding air pollution and global warming problems and developing large-scale clean, renewable energy solutions to them. Toward that end, he has developed and applied three-dimensional (3-D) atmosphere-biosphere-ocean computer models and solvers to simulate and understand air pollution, weather, climate, and renewable energy systems. He has also developed roadmaps to transition countries, states, cities, and towns to 100% clean, renewable energy for all purposes and computer models to examine grid stability in the presence of 100% renewable energy. Jacobson has been a professor at Stanford University since 1994. He has published over 185 peer-reviewed journal articles, given ~750 invited talks, published six books, and founded (in 2004) and still directs the Atmosphere/Energy Program at Stanford.
