The largest geothermal residential building in New York City just opened in Greenpoint, Brooklyn. 834 apartments. 320 boreholes drilled hundreds of feet underground — enough to heat and cool every unit in the building. Even the rooftop pool.

Geosource Energy drilled it. This conversation is about how they did it, and what it takes to build geoexchange systems at scale in dense cities, where there's already a city's worth of infrastructure below: water, gas, electric, telecom, subways, and foundations.

Geoexchange is simple to explain and hard to execute. No combustion. No fuel. Fully electric. The physics are straightforward. The delivery is not.

Building owners choose geoexchange for the operating savings. And for every dollar saved at the building level, the grid saves eight or nine — because geoexchange cuts peak demand when electricity is most expensive and most scarce.

That's a true decarbonization driver. And why cities from Toronto to Boston to New York are leaning in with more to follow.
Geosource has completed more than 400 projects. The infrastructure they install is designed to outlast the buildings it serves. Stan calls it 500-year pipe. He's seen a building come down and the borefield stay put, ready for the next one.

People assume farmers are conservative by nature. Cautious. Set in their ways.

Ryan Jones, VP of Sustainability at Indigo Ag, has a different read: farmers aren’t risk-averse. They’re risk-saturated.

Consider factors like weather, debt, input costs, labor, and fluctuating commodity prices. One bad season can set a farmer back years. So when someone shows up and says, “Change how you farm,” the first question any farmer asks is: who’s carrying the risk?

That’s the problem Indigo was built to solve. Pay farmers to adopt regenerative practices. Quantify the outcomes. Connect them to buyers through carbon markets or corporate supply chains. Today, Indigo operates in 15 countries and manages a portfolio spanning 20 million acres, delivering over a megaton of greenhouse gas reductions/removals and conserving nearly 100 billion gallons of water—and it recently announced a 12-year offtake agreement with Microsoft for 2.85 million tons of carbon removal credits.

But this conversation is about more than keeping carbon in the soil. It’s also about water. In the Mid-South rice belt, companies face an existential sourcing risk and farmers face an existential livelihood risk. And with a shared aquifer, one farmer conserving water doesn’t move the needle if everyone else keeps pumping.

The only way through is everyone moving together. And Indigo’s bet is that you get there by making the most practical thing the most profitable thing—fast enough to matter.

Forty-five million Americans live in apartments. Almost none have solar—not because the technology doesn't work, but because building owners pay for installation while tenants get the savings. It's the split incentive conundrum holding the sector back.

Owen Barrett saw this problem when he started investing in apartment buildings. Nobody in multifamily was thinking about energy—just paint colors and new countertops. He tried consulting. Nobody listened. So he raised capital, bought buildings, and installed solar himself.

The breakthrough: software that tracks each tenant's solar usage and bills them for it. Owners earn revenue. Tenants save money.

That became Shine, a company that installs solar on apartment buildings and handles everything from design to maintenance.

Shine went from 100 units in 2024 to 3,000 in 2025, projecting 20,000 in 2026. They're working with two of the five largest apartment owners in America.

Owen and Josh discuss why execution beats innovation, how rising electricity prices make subsidies irrelevant, and why doing what you promise became a competitive advantage.
