Christopher F. Jones is an associate professor of history in the School of Historical, Philosophical, and Religious Studies at Arizona State University. His research examines the historical and social dimensions of energy systems. His first book, Routes of Power (Harvard, 2014) analyzes the causes and consequences of America’s first fossil fuel energy transitions—the rising use of coal, oil, and electricity in the mid-Atlantic region between 1820 and 1930. He is currently working on a project investigating the relationships between economic theories of growth and the consumption of nonrenewable energy resources in twentieth century America. Jones teaches courses on the history of energy transitions and energy and society. He holds a B.A. in philosophy from Stanford University, and an M.A. and a Ph.D in history and sociology of science from the University of Pennsylvania.
