Entropy production delusion

It is common in knowledgeable circles to talk about the development of civilization in terms of entropy discussion. The term 'entropy...

Science failings

Greer in http://thearchdruidreport.blogspot.com/2016/07/scientific-education-as-cause-of.html provides sound insight into how decisions are made by all levels of society about the wide range of fields. In particular, he noted that physical science, in principle, is based on the gathering of evidence to improve understanding of what happens. He noted, however, that the contributions of scientists about issues in their fields are often biased by vested interests. He also points out that the findings of science often do not influence the decisions being made by various levels of society because of lack of understanding of the consequences of not taking the findings into account.
However, Greer does not take into account the failings of science to provide convincing arguments on how many aspects of natural forces always have and always will operate. Of course, sometimes exceptional scientists come up with understanding of specific issues that are gradually incorporated into the body of scientific understanding as a prelude to acceptance by society at large and influencing the decisions being made. Albert Einstein is now renowned for his contributions on the theory of relativity but that renown only came decades after his original findings were made known to the scientific community. Galileo Galilei made a major contribution to science five hundred years ago but his findings only slowly became widespread understanding of some fundamentals long after his death. This slow acceptance of novel scientific findings is understandable in view of the fact that there were also many proposals that were slowly proven to be unsound despite the arguments (and even demonstrations) by their proponents. Perpetual motion machines is by one example of the furphies that have been foisted on the community only for a while because convincing demonstration could not emerge despite attempts by scientists who did not understand the fundamental physical principles that govern these operations. They did not take into account the fact that in operations, energy does positive work while friction does negative work. 
The proposition that the emissions from the combustion of coal and other fossil fuels were having a harmful impact on environmental operations was initially made by a scientist over a hundred years ago. Slowly sufficient evidence has been gathered by dedicated scientists in many countries to prove that proposition. These peer-reviewed findings have been sufficient to convince some prominent people to support moves to deal with climate change as much as is physically possible and to introduce measures to cope with the consequences, such as sea level rise and impact on farming. This failing of science at large to recognize the consequence of the combustion of the hydrocarbons (which natural forces took eons to produce using energy from the Sun) to provide the energy to drive the technical systems while producing carbon dioxide and other emissions will continue to blight developments for a long time. It is not surprising that many people who do not understand even rudimentary physical principles are take in by how the operation of society is very largely governed by monetary decisions. The failing of physical science to educate society about the stark reality of the irreversible consumption of a vast range of limited natural resources, including the fossil fuels, together with the production of irrevocable material wastes, the irreversible aging of the vast infrastructure that provides the services society had become so dependent on and the degradation of the environment means that industrialized civilization is doomed without society understanding why. Climate disruption and ocean acidification and warming is just one emerging manifestation of nature's response to the bad decisions made by all levels of society partly because of the failure of science to foster understanding of fundamental physical operations.
These views are by a physical scientist who after a career in aeronautical research has gained understanding of the fundamental physical principles that govern all operations (including how friction allows birds and airplanes to get lift as they fly)

Difference between nenergy and senergy

The irrevocable physical properties of energy flow doing (positive) work on systems made of materials are summed up by the Laws of Thermodynamics. The associated action of friction doing negative work is common knowledge but not formally recognized by stated laws.
However, it is fascinating that there is no widespread recognition that two types of energy flow operate in civilization. They are the natural one and the synthetic one. They have the same operating characteristics described above but they differ in the consequences.
The natural energy (nenergy) flow has solar energy input, does such work as producing growth in trees (and humans) and ends up as being radiated out into space. This energy is often stored for a short period as chemical energy and it is generally not powerful. There are exceptions such as cyclones but they do not affect the principle. The natural systems on which they do work recycle or reproduce naturally so it it the sustainable process that has been going on for many years.This essentially energy income
The synthetic energy (senergy) flow uses past solar energy input stored for a long time as concentrated chemical energy in fossil fuels and does positive work in technological systems that age and do not reproduce naturally and generally do not recycle. This energy flow is generally very powerful in providing civilization with temporary goods, services and infrastructure. It is an unsustainable process because it is depleting the stock of stored energy. It is energy capital and its flow will gradually slow down in coming years as the stocks become beyond reach.
