Reading Network of Power tells us in precise detail how electric networks were created in New York, London, Newcastle and Berlin. The interest of this book lies in how it demonstrates how each country, according to its culture and traditional organization of its territory and consequently its political culture, organised from the beginning the electrification of its territory. Through men, such as Edison, and multiple, sometimes conflicting interests, each country developed the electrification of its territory using different models. Beyond the meticulous details provided by the author regarding the electrification system, emerges, in the comparison of the three models, the idealogical and political identity of each system. Great book!
