The book's strength lies in its data-driven insights, which spark reflection on civilization's energy dependencies. Smil explores the feasibility of reconstructing modern society from scratch, addressing resource demands and industrial capacities—relevant to speculative scenarios like off-world colonization. Yet, the text falters in its diffuse focus, delving into esoteric details, such as obscure energy metrics, which Smil himself acknowledges as marginally relevant. This lack of editorial restraint burdens the reader with textbook-like density, demanding significant time to parse.
While the book partially satisfies curiosity about bootstrapping civilization, it lacks a cohesive framework for understanding the full scope of necessary expertise and infrastructure. Smil notes wasteful practices but stops short of synthesizing a clear blueprint, leaving readers to piece together implications. Compared to his more accessible works, this volume's complexity may deter non-specialists.
