Coal is still the dominant source of electricity worldwide. That’s because it’s available domestically in many countries, and is cheap and easy to mine, transport and burn. But those benefits come with serious downsides: local air pollution and global CO2 emissions. We discuss with Dr. Rahul Tongia from the Centre for Social and Economic Progress, and Dr. Mark Thurber from Stanford University.

Twenty years ago, wind, solar, grid-scale batteries, and the powerlines to connect them were rare. Now they’re mainstream. Our two guests have been there since the beginning. We’ll hear how they’ve led alternative energy development and investment companies with great success. With Hunter Armistead, CEO of Pattern Energy, and Michael Harrington, Chief Investment Officer for Actis.

Fertilizer drives modern agriculture, to feed the world. It turns natural gas, nitrogen from the atmosphere, and mined minerals into plant nutrients, which end up on our plates to nourish our bodies -- but with large energy and greenhouse gas footprints. We’ll discuss benefits, challenges and potential solutions with Chrystel Monthean from Yara and Dr. Jason Haegele from ICL Group.

The Clean Air Act has reduced particulate matter pollution, ground-level ozone, carbon monoxide, nitrogen oxides and sulfur dioxides, ushering in capture technologies that have improved air quality and health. Further improvements, however, may be difficult to achieve. With Dr. Tracey Holloway, from the University of Wisconsin and NASA, and Emily Schilling, a law partner at Holland & Hart.

Russia’s energy exports fund its government and war efforts. It’s the world’s 2nd largest producer of oil and natural gas, behind the US, and has avoided energy sanctions through careful maneuvering. Because of its energy, Russia will continue to play an outsized role in global politics. With Dr. Margarita Balmaceda from Seton Hall and Harvard, and Dr. Caroline Kissane, Associate Dean at NYU.

Air conditioning has changed the world, allowing hot regions to develop, with increased comfort, health, and productivity. But these benefits come with challenges -- greater electricity demand and emissions. There are new ideas that could bring cooling to more people, with less impact. With Dr. Daniel Betts, CEO of Blue Frontier, and Dr. Chiara Delmastro from the International Energy Agency.
