Kathy Hannun is the inventor and engineer behind the renewable energy appliance provider, Dandelion Energy, which deals in underground, geothermal-sourced heating and cooling systems.

The Dandelion Energy geothermal platform is sleekly deployed 10 feet below a structure and significantly cuts cost and reliance on oil and traditional AC systems, as well as carbon emissions. In February 2021, Dandelion Energy announced it had raised an additional $30 million with Bill Gates’ venture capital firm.

Having been featured on television shows such as "This Old House" and "Designing Spaces," Hannun also recently gave a TED Talk entitled, “How to Heat Your Home Without Warming the Planet."

SBT spoke with Hannun about geothermal energy for residential and commercial uses in North America, and trends globally as structures from schools to hospitals and residences including MDU/MTUs, and commercial buildings prepare for high heating and cooling costs in the face of climate change.
