39. Greg Nemet on how solar became cheap (with Energy vs Climate)

Challenging Climate

Today’s episode is brought to you in collaboration with our friends at the Energy vs Climate podcast. Energy vs Climate breaks down the trade-offs and hard truths of the energy transition in Alberta, Canada, and beyond with energy experts David Keith, Sara Hastings-Simon and Ed Whittingham.
In this episode, they speak with Greg Nemet, a Professor at the University of Wisconsin–Madison’s La Follette School of Public Affairs. His research focuses on technological change in energy and the ways in which public policy can affect it. Listen as they discuss the trajectory of solar energy, coming down the cost curve and the energy supply chain.
