One of the groups we follow is Doomberg the green chicken on substack.
Doomberg is a group of ex-commodity industry executives, engineers, and scientists who write very insightful articles on the energy and commodity markets. Doomberg is not free, but occasionally does interviews and podcasts that are accessible to the non-paying public. Doomberg is always worth listening to and helps give you new insights and additional perspectives on the energy markets and the energy transition.
While the podcasts tend to be fairly long in length (a hour or so), it is time worth spending. I found this most recent podcast quite thought-provoking. I recommend you give it a try.
