We use a lot of biofuels in the US -- corn ethanol now makes up 10% of every gallon of gasoline. Ethanol made from cellulose, from agricultural waste or non-food crops, has been in development for years and may eventually become commercial, along with new kinds of aviation biofuels. Joining Dr. Scott Tinker to discuss is: - Dr. Valerie Reed, Bioenergy Director at the DOE - Yiying Xong from the Great Lakes Research Center. Originally aired 9/30/2024 on PBS.

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.

Last episode, our experts referenced IPCC data to explain that heat, heat waves and precipitation are trending up. While floods, fires and storms are flat or down. However, in this episode we’ll see that risk and damages from these events have increased, and we’ll look at potential solutions. Again with acclaimed environmental journalist Andrew Revkin and climate scientist Dr. Patrick Brown.

We often hear that climate change is driving extreme weather. To understand the trends, our guests dug into the IPCC data for heat waves and cold spells. Historic rainfall and current patterns. Storm frequency and intensity. What they reveal will surprise you. With Dr. Patrick Brown, climate scientist from Breakthrough Institute, and acclaimed environmental journalist Andrew Revkin.

Every text, email and social media post. Every digital photo, web search and credit card transaction. Every online purchase. Every streaming show. Nearly everything in our lives involves data coming in and out of data centers, with incredibly huge electricity demands. We discuss with Dr. Ayșe Coskun, from Boston University, and Josh Fluecke, who builds data centers for Syska Hennessy Group.

Our guests argue against conventional wisdom, that oil companies must be part of decarbonization. That solar and wind will never replace them. And that we don’t value our environment enough to take meaningful action anyway. You may not agree, but you’ll still want to hear from Dr. Nate Hagens, of the Institute for the Study of Energy and Our Future, and Tisha Schuller, CEO of Adamantine Energy.

In part 1, we focused on India’s electricity, and the potential to expand it using coal and/or solar. We continue with the growth of 2- and 3-wheel electric vehicles in India, the potential to manufacture their batteries domestically, the growth of air conditioning to combat heat waves, decarbonization targets, green building and the importance of efficiency. Here to finish their discussion with Dr. Scott Tinker is: - Padu Padmanabhan, Visiting Researcher at King Abdullah Petroleum Studies and R...

India is the third largest energy consumer and carbon emitter in the world, with the fastest growing energy demand. Today coal makes three-quarters of their electricity, with the other 25% solar and other non-carbon sources. If they follow China’s path and develop further on coal, it may be impossible for the world to meet its climate targets -- making India’s energy choices of vital importance. The experts joining Dr. Scott Tinker for this episode are: - Padu Padmanabhan, Visiting Researcher at...

For our ongoing ‘youth voice’ series, we created an energy and climate survey and asked two current and recently graduated university students to help administer it to hundreds of peers across the country, from diverse political backgrounds. The results provide a broad look at the energy and climate opinions, and knowledge, of young Americans -- and will test yours too. The youth voices joining Dr. Scott Tinker in this episode are: - Brittny Effendy, Business Analyst at McKinsey & Company - Vidh...

The US energy system, particularly our electric grids and pipelines, is constantly at risk -- from extreme events, like hurricanes, winter storms, heat waves and wildfires. And increasingly from cyber attacks, from hostile foreign powers and criminal elements. Enough that the energy industry and the US government are investing billions of dollars and working together to counter these threats. Joining Dr. Scott Tinker this episode is: - Puesh Kumar, Director of CESER at the US Department of Energ...

Sea level has been rising since the end of the last Ice Age, when continental ice sheets began to melt. In island nations and low-lying coastal areas sea level rise is contributing, among other things, to high tide flooding, and saltwater encroaching into farmland and freshwater aquifers. We’ll talk about what the future could bring, and ideas of how communities could adapt to sea level rise. Discussing sea level with Dr. Scott Tinker is: - Dr. Rachel Cleetus, Policy Director of the Climate & En...

Six hundred million people in Sub-Saharan Africa do not have modern energy -- so African nations are working to develop their energy resources. For many, the energy they do have comes from hydro. But Africa also has huge volumes of natural gas. Some funders, concerned about emissions, don’t want them to develop it. Others consider it essential to lift Africa’s people out of poverty. Joining Dr. Scott Tinker for this discussion is: - Dr. Michael Dioha, Senior Energy System Analyst at the Clean Ai...

There are many paradoxes in climate and energy: people want energy for their homes and cars… but don’t want new power lines or pipelines that could provide it. Nuclear is a zero-carbon energy source… yet many climate advocates oppose it. Some states impose EV mandates… but prohibit mining for battery metals. We’ll look to resolve these with two experts in economics, energy and climate policy. Approaching these complex paradoxes with Dr. Scott Tinker is: - Dario Liguti, Director of Sustainable En...

Cement and steel have created the modern world: they make our buildings, roads, machines and products. These two industries emit nearly as much CO2 as our entire electricity system -- but they’re difficult to decarbonize. We’ll talk about challenges and potential solutions to do so, including changing their production processes, replacing the coal they now require, and more efficient use. Discussing with Dr. Scott Tinker is: - Dr. Rebecca Dell, Senior Director for Industry at the ClimateWorks Fo...

Everything in our modern lives has energy inputs and emissions outputs -- and that’s certainly the case for our food. It’s not just all the energy that powers the equipment required to grow, transport and process our food. And the energy inputs for fertilizer required by global agriculture. But also the emissions from land, and livestock, and particularly from food loss and food waste. Joining Dr. Scott Tinker to discussion this intersection is: - Dr. Atul Jain, Professor at the Department of At...

Fission, the splitting of atoms, makes the heat that drives our nuclear reactors. Fusion, the fusing together of atoms, powers the stars, including our sun -- which means that fusion already powers Earth, just not in a way that we can control. If we could harness fusion, it would transform our world, producing limitless energy, safely and without emissions -- the holy grail of energy. Discussing fusion and more with Dr. Scott Tinker is: - Dr. Oliver Schmitz, Professor and Associate Dean at Unive...

Critical minerals and rare earth elements, essential for new energy technologies, are largely controlled by China. Global supply and demand and potential new mines in the US are pressing issues. Discussing with Dr. Scott Tinker is: - Dr. Nedal Nassar, Chief of the Materials Intelligence Research at the US Geological Survey - Dr. Adam Simon, Professor of Earth and Environmental Sciences at the University of Michigan Originally aired 10/11/2023 on PBS.
