The first systematic, quantitative appraisal of power density,
offering detailed reviews of power densities of renewable energy
flows, fossil fuels, and all common energy uses. "There's no author
whose books I look forward to more than Vaclav Smil." -Bill Gates
In this book, Vaclav Smil argues that power density is a key
determinant of the nature and dynamics of energy systems. Any
understanding of complex energy systems must rely on quantitative
measures of many fundamental variables. Power density-the rate of
energy flux per unit of area-is an important but largely overlooked
measure. Smil provides the first systematic, quantitative appraisal
of power density, offering detailed reviews of the power densities
of renewable energy flows, fossil fuels, thermal electricity
generation, and all common energy uses. Smil shows that careful
quantification, critical appraisals, and revealing comparisons of
power densities make possible a deeper understanding of the ways we
harness, convert, and use energies. Conscientious assessment of
power densities, he argues, proves particularly revealing when
contrasting the fossil fuel-based energy system with renewable
energy conversions. Smil explains that modern civilization has
evolved as a direct expression of the high power densities of
fossil fuel extraction. He argues that our inevitable (and
desirable) move to new energy arrangements involving conversions of
lower-density renewable energy sources will require our
society-currently dominated by megacities and concentrated
industrial production-to undergo a profound spatial restructuring
of its energy system.
