On the relationship of energy consumption, economic growth and standard of living — •Jürgen Mimkes — Physik Department Universität Paderborn

The production factors labour (W) and energy (E) are related to economic growth (Q) by the first law of thermodynamics. Q is an inexact differential form, which may be transformed into the exact form of entropy (d S) by an integrating factor (T). This is the second law of thermodynamics. The factor T is the mean energy consumption per household, GNP per capita or standard of living. Inexact differential forms are important for cyclic production, one may pay little energy or capital going one way (C) and receive much coming back (Y). This is equivalent to the law of economic production. Economic production is a Carnot process, in the production of goods the process runs clock wise like in a motor. In the same time capital flows in the opposite way like in a heat pump. The functions of production (Y) and consumption (C) may be calculated from the entropy. For several production factors x, y, z the production function is related to the entropy of mixing.
