About the Author

Kenneth S. Deffeyes is a renowned geologist and author whose work bridges the worlds of earth science and energy policy, offering insightful analyses of global resource dynamics. With a career spanning decades at Princeton University and extensive fieldwork in petroleum geology, Deffeyes has become a leading voice on the finite nature of fossil fuels and the implications for future energy strategies. His accessible yet rigorously scientific writing demystifies complex geological concepts for a broad audience, emphasizing the urgency of transitioning to sustainable alternatives. In his notable book, The Future of Fossil Fuels: From Hubbert's Peak (Princeton Shorts), he explores the peak oil theory pioneered by M. King Hubbert, predicting the decline of conventional oil production and advocating for proactive resource management. Deffeyes' contributions continue to influence debates on environmental sustainability and economic resilience in an era of diminishing reserves.
