Trying to bring geothermal heat pumps to scale

In this episode, I chat with Kathy Hannun of Dandelion Energy
about ground-source heat pumps, which are twice as efficient as

designed its own drills and heat pumps, and with a new 1,500-home
partnership with a developer in Colorado, it’s looking to scale
up and bring costs down.
