Deep Fission Co-Founder & CEO Liz Muller Oct 13, 2026 01:15:09 All the nuclear fuel it would take to power your entire life would fit inside a soda can.So why does a nuclear power plant cost billions of dollars and take a decade or more to build?It isn’t the reactor core. The core is small, compact, and relatively simple to build. It’s everything built around it: the containment dome, the pressurizer, the thick reactor vessel, and the safety systems designed
Crux Co-Founder & CEO Alfred Johnson
Crux Co-Founder & CEO Alfred Johnson Aug 25, 2026 01:12:30 For more than a decade, the federal government's biggest tool for accelerating clean energy hasn't been a grant or a loan. It's been the tax code. Tax credits have driven the buildout of wind, solar, and now a much wider range of technologies, like storage, nuclear, and advanced manufacturing. But there's a catch: most of the companies earning those credits don't have enough tax liability to actua

Fervo Energy Co-Founder & CEO Tim Latimer (Re-Release) Jul 16, 2026 00:59:45 Electricity demand in the U.S. is climbing faster than the grid can comfortably absorb, driven largely by AI data centers that need power 24 hours a day, seven days a week. The U.S. power system needs all the reliable clean energy it can get, and once-forgotten geothermal energy is one such resource. In the 1960s, the United States was a world leader in building large-scale geothermal power plants

Zūm Founder and CEO Ritu Narayan Jun 30, 2026 01:12:44 Every morning, 26 million children in the US get on a school bus. It is the largest mass transit system in America, and it has barely changed in 80 years. There is no real-time tracking, no route optimization, and no visibility for parents. Bus drivers still rely on walkie-talkies and dispatchers still use fax machines. Nearly half a million diesel buses are moving those 26 million children, produ

ThinkLabs AI Founder and CEO Josh Wong May 28, 2026 01:25:40 Over the years, we’ve spent a lot of time on this show talking about the grid, why it needs to expand, where it’s falling short, and what it will take to meet growing demand. We’ve talked about improving how the grid gets planned and built, and the bottlenecks that slow projects down. But even if those bottlenecks are resolved, the system itself is becoming harder to manage. Demand is rising fast,

Alex Honnold, Rock Climber & Founder, Honnold Foundation May 4, 2026 00:57:31 At a moment when the energy conversation is increasingly focused on markets, infrastructure, and scale, it can be easy to lose sight of something more fundamental: access. Roughly 750 million people around the world still live without electricity. And while the industry debates timelines, technologies, and capital flows, that reality remains unchanged for a huge portion of the global population. T

3Degrees Co-Founder and Chairman Dan Kalafatas Apr 15, 2026 01:16:17 Here’s a question: how many corporations do you know that have made a public commitment to cut their carbon emissions? Probably a lot. About 40% of the world’s largest companies have set full net-zero targets across Scopes 1, 2, and 3, according to Accenture’s Destination Net Zero 2025 report, with target-setting rising for the fourth consecutive year. But how many actually know how to achieve tho
Hydrostor Co-Founder and CEO Curtis VanWalleghem
Hydrostor Co-Founder and CEO Curtis VanWalleghem Feb 26, 2026 01:18:27 On this episode of Watt It Takes, we explore another approach to long-duration energy storage: compressed air. Curtis VanWalleghem, Co-Founder and CEO of Hydrostor, started the company in 2010 after confronting surplus power challenges at Bruce Power. Without a traditional founder background, he set out to build storage systems that use compressed air and underground hard rock caverns to deliver t

It’s a problem statement.Mitch Lee grew up around boats. He loved being on the water, but he also experienced firsthand how loud, smelly, maintenance-heavy, and frustrating boat owner
Voltus Co-Founder and CEO Dana Guernsey
Voltus Co-Founder and CEO Dana Guernsey Dec 29, 2025 01:26:37 As an aging grid faces rising demand, increasing complexity, and more frequent stress events, one thing has become clear: we don’t just need more power, we need power that can show up at the right time, in the right place, and at the right price. What’s far less settled is how we get there. Should large energy users build their own power? Should they treat the grid as something to work around rath
Tyba Co-Founder and CEO Michael Baker
Tyba Co-Founder and CEO Michael Baker Nov 26, 2025 01:18:47 ​​As load growth pushes the grid to its limits, the energy transition increasingly depends on one technology: storage. Batteries are becoming the backbone of reliable, clean power, and according to a recent UBS analysis, AI-driven data centers are set to trigger a “boom cycle” for energy storage in the next five years.As more clean energy comes online and global energy demand surges, batteries are

Jennifer Granholm, Former Director, Department of Energy Oct 31, 2025 01:09:17 At a moment when our country can feel deeply divided, and when progress on clean energy can feel uncertain, this month's guest — former U.S. Secretary of Energy and two-term Governor of Michigan, Jennifer Granholm — couldn’t be timelier.It was the perfect moment to take stock of where we are as an industry. After years of historic progress, we’re now facing growing uncertainty about what comes nex
