Good point by Vaclav Smil in his review of Dan Yergin’s latest:
The book, which is sliced into more than 400 short sections, covers policy and economics more than science and technology. Its analysis of energy sources is uneven. Coal, for example, warrants a single page. Yet during the twentieth century, coal supplied the world with more energy than did oil. In 2010, coal combustion accounted for 30% of all global commercial energy (compared with nearly 34% for oil) and 40% of electricity generation.
