Futurists of the past dreamed of tapping into the heat of the Earth's mantle to supply our energy needs, but today's geothermal provides only a tiny fraction of the power we use. In today's episode, we'll be discussing what's next for geothermal, its possible advantages over solar and wind power, and the obstacles it faces. I'm joined by Jamie Beard to answer those questions and more.

Jamie is the founder and executive director of the Geothermal Entrepreneurship Organization at the University of Texas at Austin.
