Design a Podcast logo

We need a logo for a podcast called "Ergs & Equilibrium" which is an interview-style podcast discussing recent papers in energy and environmental economics. It just needs to be a relatively simple/minimalist logo that has the name of the podcast and a simple design.

We would prefer if it were more general and not just a picture of a lightbulb, battery, lightning bolt, etcetera. Essentially no general "energy" or "electricity" clipart-style designs if possible!
