I’m currently reading through Sustainable Energy – without the hot air by David J.C. MacKay, FRS, which I recommend to anyone interested in energy or energy policy. I’m particularly impressed by the graphs and diagrams in the book, both for the laboriously-collected data they represent and for their power to convey important points quickly and clearly. (Example).
The visual imagery evoked by the prose is powerful too: in a section discussing the merits (and lack thereof) of having a large number of people make a small saving each, here is what MacKay has to say:
The “if-everyone” multiplying machine is a bad thing because it deflects people’s attention towards 25 million minnows instead of 25 million sharks. The mantra “Little changes can make a big difference” is bunkum, when applied to climate change and power. [link]
