Gareth Roberts: "Geology, Optimism, & Something Completely Different"
Episode 61
March 8, 2023
(Conversation recorded on December 19th, 2022)
Show Summary
On this episode, geologist and entrepreneur Gareth Roberts joins Nate on the podcast to discuss the geological science behind how we find, extract, and deplete fossil hydrocarbons. Gareth and Nate also unpack how financial policy, government, and an energy transition interact with an aging hydrocarbon-based grid. What does all of this mean for our energy future? How can we use humor to process and make sense of these societal challenges? How do scientists, communicators, and planners come together to respond to such challenges?
