Energy in Nature and Society is a systematic and exhaustive analysis of all the
major energy sources, storages, flows, and conversions that have shaped the
evolution of the biosphere and civilization. Vaclav Smil uses fundamental
unifying metrics (most notably for power density and energy intensity) to
provide an integrated framework for analyzing all segments of energetics (the
study of energy flows and their transformations). The book explores not only
planetary energetics (such as solar radiation and geomorphic processes) and
bioenergetics (photosynthesis, for example) but also human energetics (such as
metabolism and thermoregulation), tracing them from hunter-gatherer and
agricultural societies through modern-day industrial civilization. Included are
chapters on heterotrophic conversions,
