"Since 1859, oil has enabled and defined our economic, social and political landscape. Throughout this time, abundant supply ensured low, stable prices and the inner workings of the oil industry remained relatively obscure. Following a century and a half of relative calm, oil prices have become much more volatile as the sustainability and growth of reliable supply sources have been brought into question. This book provides a guide to oil; from its history, to sources of supply and drivers of demand; from how prices are determined daily in global wholesale oil markets, to how those markets are connected to prices at the pump." -- Book jacket.
