Climate investor and philanthropist Tom Steyer, recipient of the 2025 Charles David Keeling Memorial Lecture, talks about the current and future state of energy. In a conversation with Scott Lewis of Voice of San Diego, Steyer argues that capitalism and policy must work together at scale, and highlights the marketplace rise of renewables like solar and EVs alongside challenges like slow fossil-plant retirement, grid constraints, and the need for longer-duration storage. He also discusses emerging options such as advanced geothermal and nuclear. The Keeling Memorial Lecure is given by a prominent member of the global change community able to speak on topics that reflect the legacy of Keeling's work. [Science] [Business] [Show ID: 41034]
