327:(a Romanian-born economist whose work in the 1970s began to define this new approach) models the economy as a living system. Like all life, it draws from its environment valuable (or “low entropy”) matter and energy, for animate life, food; for an economy, energy, ores, the raw materials provided by plants and animals. And like all life, an economy emits a high-entropy wake, it spews degraded matter and energy, that is... waste heat, waste gases, toxic byproducts, the molecules of iron lost to rust and abrasion. Low entropy emissions include trash and pollution in all their forms. Matter taken up into the economy can be recycled, using energy; but energy, used once, is forever unavailable to us at that level again. The law of

His research reflects his interest in understanding and developing analyses and computer simulation models of the complex systems of nature and humans and their interactions. Halls focus has been on

Central to Halls argument is an understanding that the survival of all living creatures is limited by the concept of energy return on investment (
317:"Energy used by the economy is a proxy of the amount of real work done in our economy," according to Charles A. Hall. In the 1980s, Hall and others hypothesised, "Over time, the Dow Jones should snake about the real amount of work." Twenty years later, a century's market and energy data shows that whenever the
