Böcker av Robert U. Ayres

The purpose of this book is three-fold. The first purpose is to posit that the fundamental substance of the universe is energy, and that energy is required (consumed) for any material transformation, or information transmission. The labor theory of value, articulated by the physiocrats and elaborated by Adam Smith, David Ricardo, J.B. Say and Karl Marx was a rough first approximation of the value creation process, in the 17th and 18th centuries, but is now obsolete. Labor is now (mostly) performed by machines, not by humans (or animals). The second aim of the book is to argue that the economy is a living (open) system -- an ¿island of order¿ ¿that exists far from both thermodynamic and economic equilibrium. Order is achieved by dissipating a flux of exergy. Economists frequently emphasize the equilibrium assumption, introduced originally by Leon Walras in 1854. But in reality, biological systems and human social systems are dissipative cycles, far from both thermodynamic equilibrium, and economic equilibrium, yet stable and capable of evolution, driven by the solar exergy flux. The third aim of the book is to re-emphasize, that ¿ being open ¿ the economic system cannot be regarded as a collection of individual competitive utility-maximizing transactions. There are, increasingly, important possibilities for cooperation instead of competition. Moreover third party effects, both ¿bads¿ (externalities) and the ¿public good¿ (happiness) ¿ need to be incorporated into the socio-economic decision making process.

Eminent physicist and economist, Robert Ayres, examines the history of technology as a change agent in society, focusing on societal roots rather than technology as an autonomous, self-perpetuating phenomenon. It evolved from a need to pump water out of coal mines, driven by a need to burn coal instead of firewood, in turn due to deforestation.

It is true that economic growth has accelerated in recent centuries, and it is true that billions of people have been lifted from poverty.

If the first industrial revolution was the substitution of steam power for human and animal muscles, the present revolution is the substitution of electronic sensors for human eyes and ears, and computers for human brains, at least in a certain category of routine 'on-line' manufacturing operations.
