Acknowledgments

These lectures owe their existence to Rhys Williams, who invited me to spend three months working on them at the University of Glasgow in summer 2022, and the Leverhulme Trust, which awarded me the fellowship that made that trip possible. In Glasgow, my friend and colleague Graeme Macdonald was an invaluable interlocutor. I miss our daily midafternoon coffee sessions, where we talked energy ideas and political ideals. Mark Simpson’s editorial suggestions were, as usual, superb. I owe everything good in these pages to Eva-Lynn Jagoe, Tanner Mirrlees, and Andrew Pendakis—all of them always know the right thing to say. And an enormous thanks to Valerie Uher for helping on this project, just as she has on so many others over the past six years.
