All life on earth is dependent on energy from the sun, but one species has evolved to be especially efficient in tapping that supply. This is the story of the human species and its dedicated effort to sustain and elevate itself by making the earth's stores of energy its own. A story of slow evolutionary change and sharp revolutionary departures, it takes readers from the origins of the species to our current fork in the road.nbsp;With a winning blend of wit and insight, Alfred W. Crosby reveals the fundamental ways in which humans have transformed the world and themselves in their quest for energy. When they first started, humans found fuel much like other species in the simple harvesting of wild plants and animals. A major turn in the human career came with the domestication of fire, an unprecedented achievement unique to the species. The greatest advantage from this breakthrough came in its application to food. Cooking vastly increased the store of organic matter our ancestors could tap as food, and the range of places they could live. As they spread over the earth, humans became more complicated harvesters, negotiating alliances with several other species--plant and animal--leading to the birth of agriculture and civilizations. For millennia these civilizations tapped sun energy through the burning of recently living biomass--wood, for instance. But humans again took a revolutionary turn in the last two centuries with the systematic burning of fossilized biomass. Fossil fuels have powered our industrial civilization and in turn multiplied our demand for sun energy. Here we are then, on the verge of exceeding what the available sources of sun energy can conventionally afford us, and suffering the ill effects of our seemingly insatiable energy appetite. A found of the field of global history, Crosby gives a book that glows with illuminating power.… (más)

Until recently, all the energy humans ever used was, ultimately, solar. Muscles got their energy from food. The bottom of the food chain rested on plants, which got their energy from the sun. When humans tamed fire, they burned wood...a plant. Peat, coal, natural gas, and oil are also derived from plants. They are forms of stored solar energy compressed and compacted over many millennia. Electricity was, and still is, generated mainly from burning coal, gas, and oil. Hydroelectric plants produce some, but they rely on the planetary water cycle, which is driven by evaporation and precipitation powered by the sun.
This book is a brief account of humanity's still growing quest for usable energy. It offers no real recommendation for where that will be found, other than a cautious nod toward nuclear power and especially the hope of fusion at some point in the future. It does not, however, foresee the delay to the ITER (International Thermonuclear Experimental Reactor) and seems to place more hope on it than perhaps is warranted given the delays, cost increases, and political uncertainty surrounding it. It also doesn't foresee advances in the efficiency of solar voltaic cells or their declining cost, and seems to dismiss their potential too quickly. Although this was published in 2006, it already feels a bit dated. Perhaps this is simply another example of how quickly things change in our age. ( )

A short and incisive history of humans and their use of the sun's energy, in all its forms, throughout history. A timely reminder of what we are burning every single day. ( )

I read over 100 books a year and this probably ranks as the most unmemorable book I read in the past 12 months. There is nothing terribly wrong with it, it's mostly factually accurate and well written, just very conservative, unimaginative, not totally up to date on current thought and adds nothing new. It might be a good introduction for someone who has no background on the subject and it is very short. ( )
