A Crude Awakening paints a bleak picture for the supply of oil. Or, more poignantly, the bleakness of a world without abundant and cheap energy. The point ignored by the film, though, is the abundance of coal in the US. The most effective means of realizing the energy potential in coal is electric power plants. This is an unattractive option, because of the dire environmental impact, and the relative inconvenience of coal versus oil (pretty hard to fly a coal powered commercial airliner).
