We all know that the Sun is responsible for our light, and most of us would throw in our warmth as well, but Alfred Crosby’s sweeping adventure of a popular science book reminds us that in fact we owe practically all our energy to the Sun. Through each of the phases of the book, looking at energy from our own muscles (burning plant life, which gained energy from the Sun), from steam power (typically burning coal, which was plant life) through internal combustion (yes, oil from plant life) we have been dependent on the Sun’s energy. Hydroelectric power? From the Sun, of course, evaporating water that can fall as rain to fill the reservoir behind the dam. Wind power? The Sun again, which powers the weather. The only rogue contributors are nuclear, wave power and geothermal (and a lot of that heat came from the Sun). By now you should get the idea that this is really a celebration of humanity’s relationship with energy, most of which has come from the Sun, looking both at the way...
