For decades, BP and Shell extracted the minerals, finance and skills of the UK. Always behind the scenes, Big Oil drove Britain's economy and profoundly influenced its culture. Then, at the start of the 21st Century, the tide seemed to go out - Britain's refineries and chemical plants were quietly closed; the North Sea oilfields declined. Now, while the country goes through the seismic upheavals of Brexit and the climate emergency, many believe the age of oil to be almost passed. However, as Crude Britannia reveals, reports of the industry's death are greatly exaggerated. Taking the reader on a journey across Britain - from North East Scotland, Merseyside and South Wales to the Thames Estuary and London - James Marriott and Terry Macalister tell the story of Britain's oil-stained past, present and future; of empire, economic deprivation and continuing political influence. The authors speak to oil company executives and oil traders, as well as former shipyard and refinery workers, film makers and musicians, activists and politicians, putting real people and places at the heart of a compelling political analysis. Offering a rare insight on how to read the history of modern Britain, Crude Britannia shows what needs to be done to create a new energy system, that tackles climate change and underpins a fairer democratic society.
