Electrical power and ‘modern’ society are often linked in many ways. Areas of the world not using electricity may be seen as ‘backward’. Even in the U.S. these days there is much debate about movement from fossil fuels to sustainable electricity for more parts of technology. Many Americans would be lost if they had to go 24 hours without access to their electrically powered cell phones and computers. There are plenty who might argue the opposite, that ever-changing technology, at least communications technology, tends to isolate us more than bring us together. Where electricity prevails, time has less meaning. Any activity can be lighted at any time of the day. Sleep patterns also tend to be altered in societies with electrification. For example, despite changing daylight hours throughout the year people will likely keep the same work schedule. Students may be accustomed to all-night cramming sessions the night before a big test. Many people fall asleep to the musings of late-night comics. Before electrification, circadian rhythms tended to be primarily timed with the rising and setting of the sun.
In this work, Thomas Hughes shares historical events as electrical power was harnessed from the early days of Edison and Tesla. He pays attention to expansion of electrical technology within the United State, particularly in Chicago and California. He further reviews electrification in London and Berlin. Hughes also comments on how electricity and society affected each other in these four cities. Students of technology and society will recognize these topics. Technology transfer refers to the spread of ideas and invention beyond national borders. He looks at critical problems in advancing technology, sometimes referred to as reverse salients. Hughes examines social conflict and its affect on electrification. This includes personal rivalries among inventors, as well as companies attempting to grow within each of the cities examined. Technological momentum and the effects of World War I (both advancing and inhibiting electrical growth) offer an interesting take. Many scientists and technologists continued to share information despite the war, though others were prohibited. Berlin, for example, was somewhat isolated from others during the war, but war needs caused the German government to channel funds into electrical power for manufacturing of weapons and munitions. Unlike World War II, there was little air bombardment beyond the front lines, so industry by and large remained intact.
Thomas Hughes does not discuss electrification in eastern or southern societies. Perhaps this is a function of scale. One can only put so much into a book. Perhaps it is because he feels these particular cities are similar enough to point to socio-technical trends that perhaps would be different in other societies. Even among the focus histories he has included, there are significant differences as noted in his work. For example, each of the histories show different political and economic contexts. As a result, electrical power generation and transmission grew in very different ways. Standardization was difficult in some locations and centrally managed in others. By looking at the growth of a single technology, Hughes is able to expose the co-production (even co-dependence) of these societies and electricity.
