    Cogent analysis by a keen mind
  

*by B***R on Reviewed in the United States on December 28, 2008*

A scholarly work relatively free of advocacy, except for advocating sticking to the facts.  You will find more pages meticulously diagnosing the history of the energetics of agriculture, transportation and steel making than you will pages forecasting what future energy trends will be, or should be.  The author reviews the history of some of these forecast attempts.  Here is a sample from page 358:  "Reasons for the large number of wrong forecasts can be found in the herdlike behavior of forecasters smitten by prevailing moods".  "The U.S. Atomic Energy commission's 1974 forecast had 260 GW installed in the United States by 1985, and 1.2 TW in 2000. The actual 2000 number was 81.5 GW, and there were no clear prospects for fusion."  "The same adjectives used to extol nuclear generation - inexhaustible, cheap, nonpolluting - reappeared in glowing descriptions of renewable energetics published during the 1970s as the advocates of small-scale, decentralized energy production promised a new, morally superior millennium devoid of nuclear and fossil fuel sins."  And on page 362: "...by the year 2000...new renewables contributed just 3.2 EJ, only one-tenth of Lovins's forecast."The author wants to avoid falling into  Lovins's and the AEC's trap.  Nevertheless,  scientifically sound constraints on future activity are offered without hesitation, for example: the potential for hydroelectric development, the limits of photosynthesis and geothermal fluxes.  But on page 384, the author perhaps becomes polemical: "The ultimate makeup of a new global energy system that may dominate in the second half of the twenty-first century will not resemble currently fashionable scenarios."  Notice the choice of words: "will not" rather than "may not".  Later on page 382: "I strongly believe that the key to managing future global energy needs is to break with the current expectation of unrestrained energy use in affluent societies."  Whose expectation?  I live in an affluent society and my energy use is not unrestrained and I don't expect it to be.  I presume the sentence applies to other guys, who need to  be broken.Well, let's not nitpick over that sentence.  There is no scientific principle more productive than the principle of conservation of energy (my advocacy).  There is no analysis of "how stuff works" with greater predictive power than that provided by a monitoring of the energy conversions.  This book is a masterpiece by a honest scientist with enormous skill in organizing knowledge of energy.See MIT Press for a detailed preview inside the book.

How much energy does the Earth receive from the Sun every day?  Why are humans able to live in environments ranging from very cold to very hot - a wider range than any other mammal? Could we run our civilization on biofuels, wind power, solar, or geothermal energy? Does extracting uranium from seawater to generate electricity cost more energy than it supplies? How much improvement can we expect in crop yields from genetic engineering? How efficient are compact fluorescent lamps versus incandescent bulbs or the new white LEDs? What was special about James Watt's steam engine?Professor Smil has made a thorough and wide-ranging survey of the knowledge we have accumulated about energy flows on the grand scale. Inside the book you can find the answers to some of these questions. But, more importantly, in this book you can find enough about the processes involved to be able to assess other people's answers. The book gives you the building blocks to create your own knowledge.On the negative side, tne book is marred by hundreds of small typos, and grammatical and formatting errors, for example "photovaltaic", "the France", "01.6".  Sometimes the mistakes change the sense of what is being said: 1.6MJ per molecule is a whole different kind of energy to 1.6 MJ per mole - 6.02x10<sup>23</sup> molecules. Some diagrams have incorrect units - for example, in fig 3.11 a and b, the horizontal scales are log of body mass, and the vertical scales are log of growth rate and body length respectively. Once or twice, the text and diagrams appear to conflict.  These are relatively minor irritations, though.The book could be improved by including sub-headings or marginal notes when there is a change of topic within a section. For example, section 4.3, Locomotion, compares swimming, flying, and running, and then discusses some details of each in turn. So it has four sub-sections.  However, there is no marker in the text to indicate the change of sub-topic. The whole section is just an undifferentiated mass of text, equations, and diagrams.Never mind. I am satisfied with the book as it is, and I am sure I will be referring to it many times in the coming years.

    Vaclav Smil does his homework and is relevant
  

*by S***N on Reviewed in the United States on June 16, 2016*

Vaclav Smil does data collection and  research combined with years of viewing globes confrontation with man from an economists viewpoint that is like no other. Conclusions are harsh, but realistic. Reading his books in sequence is the best way to understand the links and relevance of every piece.
