Power Density by Vaclav Smil

Power Density by Vaclav Smil

"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.

Vaclav Smil has authored 35 books and over 400 papers in the subjects of materials, energy, environmental and population change, food production and nutrition, technical innovation, risk assessment, and public policy. His research interests are diverse and include a variety of disciplines. He is a Member of the Order of Canada, a member of the Royal Society of Canada (Science Academy), and a Distinguished Professor Emeritus at the University of Manitoba. Foreign Policy named him one of the top 100 global thinkers in 2010. He was the first non-American to receive the American Association for the Advancement of Science Prize for Public Understanding of Science and Technology. He has served as a consultant for several US, EU, and international agencies, and has spoken at approximately 400 conferences and workshops in the United States, Canada, Europe, Asia, and Africa. Finally, in a Wired.com story in 2013, he had the honor of having Bill Gates say, There is no author whose books I look forward to more than Vaclav Smil.
