“In Steam Power and Sea Power, Steven Gray explores the political, economic, social, and cultural implications of the British Navy’s transition to, and reliance on, mineral energy. Drawing from a diverse array of government and naval correspondence and reports, parliamentary papers, diaries and journals, ships logs, and a number of newspapers and periodicals from across the British empire, Gray brings together the well- established literature on the relationship between the Royal Navy and the British empire with the quickly-growing field of energy history.” (Andrew Watson, Canadian Journal of History, Vol. 53 (3), 2018)
