Arithmetic, Population and Energy

A brilliant lecture by Dr. Albert A. Bartlett, professor of physics, that looks at population growth, energy use, and sustainability in light of basic arithmetic. Insightful and alarming, Bartlett shows why "sustainable growth" is an oxymoron and how many "experts" do not get this. According to Bartlett, a person in the U.S. on average consumes ~30 times the resources than a person in an underdeveloped country. One encouraging trend I found elsewhere is that per capita energy use in the U.S. has fallen in the last three decades though more than offset by population growth in the U.S., and by growth in population and per capita energy use in developing countries. Hardly a better case can be made for zero population growth and massive investments in renewable energy than the one made by Bartlett (from 2002, via 3QD).
