Al Bartlett's video “Arithmetic, Population, and Energy”1 spells out many of the complex issues related to energy use in our society. Bartlett makes the point that basic arithmetic is the fundamental obstacle preventing us from being able to grasp the relationships between energy consumption, population, and lifestyles. In an earlier version of Bartlett's video, he refers to a “Hagar the Horrible” comic strip in which Hagar asks the critical question, “Good…Now can anybody here count?”
