How did the world become addicted to fossil fuels? Of course, when reference is made to the Middle East in answering this question, it is usually done so in relation to oil. In his latest book, Powering Empire, On Barak instead turns attention to coal, not only for its role in transforming the region before oil, but also in connecting consumption habits across the world through imperial networks. In order to understand how we might achieve decarbonisation faced with global climate crisis, Barak posits, we must understand how carbonisation became global in the first place. Barak's book investigates this issue by combining environmental, social, cultural, intellectual and labour history approaches, offering a new and rich account of how coal became ever more intertwined with mundane life in the nineteenth and early twentieth centuries. It is an extremely valuable and ground-breaking work to add to the burgeoning field of 'Energy Humanities' and should be of interest to scholars concerned with the history of the modern Middle East, British empire and global capitalism.As in his previous book, On Time, Barak borrows methods from science and technology studies (STS) to examine the technopolitics of an array of objects, technological artefacts and infrastructures. 1 These were all related in some way to coal: steamships, desalination plants, refrigerators, irrigation pumps, lighthouses, risk management and coal itself. Yet Barak also seeks to marry this 'New Materialism' with Marxian materialism through examining how these were embedded within global capitalism and imperial power structures, alerting the reader to labour conditions and forms of agency in steamship engine rooms, coal mines and at coal heaving ports, as well as pointing to the early geopolitics of 'energy security'. He does so by This is the version of the article accepted for publication in Middle Eastern Studies, 57 (1). pp. 168-172 (2021), published by Taylor and Francis.
