Clean Energy Has to Outcompete Fossil Fuels (Not Cancel Them)

It feeds half the world. It Also Emits 2% of Global CO₂. Can We Fix It?

In this episode of Future in Bloom, host Steph talks with Dr. Lea Winter, a chemical and environmental engineering professor at Yale, to explore how we can redesign the basic chemistry of our economy and actually reuse CO2. Lea breaks down why carbon isn’t just a pollutant to get rid of but an essential building block of our everyday lives. Her lab is developing ways to take CO2 from the atmosphere or industrial emissions and convert it into fuels, chemicals, and materials using reactions that could one day replace fossil-fuel-based manufacturing. Lea also explains how synthetic fertilizer enabled the population boom of the 20th century, but at a steep cost: massive fossil fuel dependence, significant CO2 emissions, and widespread nitrogen contamination of groundwater and ecosystems. Her lab is pursuing green ammonia pathways that use only air, water, and renewable electricity. Together, Lea and Steph discuss her work on transforming wastewater into a resource recovery opportunity, converting nitrogen contaminants into ammonia for fertilizer. Lea shares her vision of a truly circular chemical economy, one designed to eliminate waste, increase resilience, and expand access to essential resources for communities around the world.

Impermanent Philanthropy: A new way to think about legacy with Santhosh Ramdoss

What if the best thing a foundation could do was plan its own ending? In this episode of Future in Bloom, Steph Speirs sits down with Santhosh Ramdoss, President & CEO of Gary Community Ventures, to explore a radical idea that could reshape philanthropy: Impermanence. By 2035, Gary will have spent every dollar of its assets in service of Colorado kids and families, which intentionally departs from how most foundations operate. Santhosh shares the founding vision behind Gary’s sunset, why traditional endowments behave more like dams than rivers, and how his team is working to transform institutional wealth into community well-being. He also opens up about his own journey, what nature can teach all of us about letting go, and how to leave the world better than we found it.

Better Soil with Natural Carbon Removal: A Yale Geochemist Explains

What if one of the most powerful climate solutions wasn’t something we needed to build, but something the Earth has been doing for billions of years? In this episode, Steph Speirs sits down with Dr. Noah Planavsky, a geochemist at Yale University and one of the world’s experts on enhanced rock weathering. They explore how crushing silicate rocks like basalt and spreading them on farmland can accelerate a natural process that pulls CO₂ from the atmosphere and locks it in the ocean for thousands of years. All this both improves soil health and boosts crop yields. Dr. Planavsky breaks down the science, explains why farmers already understand soil chemistry better than most academics, and makes the case that carbon removal should benefit the communities where it operates. He shares his choice to co-found two carbon removal companies and then walk away from any financial stake so he could advocate for transparency and sound science.

The 200 People Who Control Your Electricity Bill

Charles Hua, founder of Powerlines and former US Department of Energy strategist, makes the case that America’s energy affordability crisis is a regulatory problem. With 80 million Americans struggling to pay their utility bills, and rates rising at the fastest pace in a generation, Charles points out the real power to control consumer prices resides with Public Utilities Commissioners, roughly 200 people he calls “The Supreme Court Justices of Energy.” This small group controls more than $200 billion a year in utility spending. This, all within a system designed almost a century ago. Steph and Charles discuss why the grid runs at just 50% efficiency, how “capex bias” rewards utilities for building new infrastructure instead of optimizing what already exists, what the rise of data centers could mean for your power bill, and the inexpensive and solutions we could implement quickly if they get the greenlight from regulators. Whether you’re in climate tech, policy, or just nervous to open your electric bill lately, this episode will open up a world we don’t see or think about that often, happening behind every flip of a lightswitch.

Clean Energy Has to Outcompete Fossil Fuels (Not Cancel Them)

Aliya Haq has been involved in the environmental movement since she was eight years old, protesting an incinerator in her rural hometown. Over 25 years she’s led policy at Greenpeace, Breakthrough Energy, and now the Clean Economy Project. In this conversation, she tells Steph Speirs why the old playbook of “stop bad things” no longer meets the moment, and what it takes to actually build a clean economy fast enough to matter. Aliya and Steph dig into the practical questions facing every climate tech founder and investor right now: Why does clean energy need policy to exist? How do permitting reform, transmission, and interconnection actually get unstuck? And how do companies navigate a moment where wealthy funders are backing away from climate, and federal policy feels like quicksand? It’s a candid and clearsighted conversation about what it means to shift from activist to builder–and why the economics of clean energy are already winning, if we let them.
