Colorful and authoritative, this poster traces the history of the Oil Age from its beginnings in the hills of western Pennsylvania in 1859 to its rise as the engine of global industrial economies. The poster's main chart features a year-by-year rendering of worldwide oil production from 1859 to 2050 with projections of future production based on Colin Campbell's Oil Depletion Model. Historical annotations as well as detailed data on production, trade and reserves make this poster a versatile tool for presenting the realities and implications of global oil production and its impending peak.
