Apparently written to bring his work and thought before a broad public, this book is a concise and interesting summary of a large body of work and thought from this distinguished economic and demographic historian. The use of coal in industrializing Britain is core of this book. The importance of coal use in the Industrial Revolution is known well and has been commented upon by virtually every historian or economist who has dealt with this topic. Wrigley has a novel and interesting view of this crucial phenomenon. Wrigley contrasts the limited growth potential of an "organic" economy where productivity will be eventually constrained by negative feedbacks due to the limited resource of wood as an energy source with an "inorganic" economy where this energy bottleneck is absent.
In contrast to many other scholars who have focused on how the Industrial Revolution started, Wrigley examines why it didn't sputter out. Wrigley covers a number of interesting aspects of this concept. He points out the significant growth potential of pre-industrial, "Smithian", capitalist growth and discusses interesting ways in which this occurred in England. There are nice dicussions of improvements in agricultural productivity, urbanization, the velocity and volume of trade, and rising consumer demand. All of these interacted in interesting ways to enhance economic growth. But, negative feedbacks due to limited land and limited wood production would eventually have curtailed many of the processes. The employment of coal, both for domestic heating and industrial production, prevented these negative feedbacks from operating. His counter-example is the 17th century Netherlands, where considerable economic modernization occurred but ultimately stagnated.
Simultaneously, coal use stimulated some positive feedbacks of its own. Increasing use of and demand for coal, for example, stimulated improvements in transportation and provided considerable impetus for the development of the great technological innnovation of steam power.
This short book contains quite a bit of interesting analysis. There is good discussion of the relatively long prelude to the Industrial Revolution, English demography, the pessimism of classic economists like Smith and Ricardo, and quite a few other topics.
