For this of the podcast How to Save a Planet, the hosts interview Visiting Scholar Gretchen Bakke on probably the greatest boundary to all-renewable energy: our outdated energy grid.

How to Save a Planet is a Spotify original podcast and Gimlet production. The two hosts, journalist Alex Blumberg and scientist Ayana Elizabeth Johnson, interview transdisciplinary experts of many research fields in an effort to better understand the current climate crisis, how it could have been avoided, and what we can do to help fix it.
