Globally, we burn as much fossil fuel heating homes as we do driving cars, yet home heating rarely gets climate attention, even though it drives massive energy use, grid strain, and raises household costs. In this episode of Hardware to Save a Planet, host Dylan Garrett speaks with Dan Yates, CEO and Chairman of Dandelion Energy, about why geothermal heat pumps may be the most overlooked solution in residential decarbonization. Dan explains how tapping the stable temperatures beneath our feet can slash home energy consumption, dramatically reduce peak electricity demand, and outperform air source heat pumps during extreme weather. He shares how Dandelion cut system costs through builder partnerships, making geothermal viable at scale, and why utilities increasingly see it as a grid-stabilizing asset. The conversation explores how hardware innovation, smart incentives, and new business models can align to make clean, electric home heating both affordable and practical.
