Episode 87: Grant Gunnison, Zero Homes

America’s homes are quietly fueling the climate crisis. Residential buildings account for nearly 20% of U.S. emissions, yet retrofitting them remains a maze of contractors, estimates, and outdated systems. It’s one of the hardest — and most important — challenges in the clean energy transition. In this episode of The Capitalist Hippie Podcast, host Marco Pimentel sits down with Grant Gunnison, Founder of Zero Homes, a startup turning that problem into opportunity. After building space lasers at NASA, Grant set out to reinvent the way homeowners power their houses — replacing weeks of confusion with a single digital experience that takes less than an hour.
