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.Energy level densitiesEnergy auditingRenewable energy sourcesPower resourcesElectronic books.Energy level densities.Energy auditing.Renewable energy sources.Power resources.333.79Smil Vaclav140188CaBNVSLCaBNVSLCaBNVSLBOOK9910467295503321Power density1893862UNINA00895oam 2200229z- 450 99101331798033211-4673-5606-9(CKB)3390000000045181(EXLCZ)99339000000004518120220628c2012uuuu -u- -engSignal Processing and Information Technology (ISSPIT), 2012 IEEE International Symposium onIEEE1-4673-5605-0 1-4673-5604-2 2012 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)2012 IEEE International Symposium on Signal Processing and Information Technology Signal Processing and Information Technology PROCEEDING9910133179803321Signal Processing and Information Technology (ISSPIT), 2012 IEEE International Symposium on2539569UNINA
