I am a historian of energy, environment, and economics. My research and writing explore topics including energy transitions, infrastructure, fossil fuel dependence, sustainability, and economic growth.

My first book, Routes of Power, examines America’s energy transitions to coal, oil, and electricity from 1820 to 1930. I am currently writing a book studying the relationships between economic theories of growth and planetary resources provisionally titled The Invention of Infinite Growth.

I am editor of the H-Environment Roundtable Reviews.

I teach history at Arizona State University and can be followed on Twitter (@EnergyHistorian).
