Thermoeconomics

Thermoeconomics is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Thermoeconomics rather than just read about it. In short: Thermoeconomics, also referred to as bioeconomics or biophysical economics, is a school of heterodox economics that applies the laws of thermodynamics to economic theory. Thermoeconomics applies statistical mechanics to economic value.

Key takeaways

  • Thermoeconomics belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Thermoeconomics to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Thermoeconomics from memory before moving on to harder problems.

Reference excerpt

Thermoeconomics, also referred to as bioeconomics or biophysical economics, is a school of heterodox economics that applies the laws of thermodynamics to economic theory. Thermoeconomics applies statistical mechanics to economic value. It is a subfield of econophysics, extenuating to ecological economics. Thermoeconomics studies the ways and means by which human societies procure and use energy and other biological and physical resources to produce, distribute, consume and exchange goods and services, while generating various types of waste and environmental impacts. Biophysical economics builds on both social sciences and natural sciences to overcome some of the most fundamental limitations and blind spots of conventional economics. It makes it possible to understand some key requirements and framework conditions for economic growth, as well as related constraints and boundaries.

Thermodynamics

"Rien ne se perd, rien ne se crée, tout se transforme" "Nothing is lost, nothing is created, everything is transformed."

-- Antoine Lavoisier Thermoeconomists maintain that human economic systems can be modeled as thermodynamic systems. Thermoeconomists argue that economic systems always involve matter, energy, entropy, and information. Based on this premise, theoretical economic analogs of the first and second laws of thermodynamics are developed. The global economy is viewed as an open system.

Moreover, many economic activities result in the formation of social classes. Thermoeconomics applies the statistical mechanics of non-equilibrium thermodynamics to model these activities. In thermodynamic terminology, human economic activity may be described as a dissipative system, which flourishes by consuming free energy in transformations and exchange of resources, goods, and services.

Energy return on investment

E R O I = Energy returned to society Energy required to get that energy {\displaystyle EROI={\frac {\text{Energy returned to society}}{\text{Energy required to get that energy}}}}

Thermoeconomics is based on the proposition that the role of energy in biological evolution should be defined and understood not through the second law of thermodynamics but in terms of such economic criteria as productivity, efficiency, and especially the costs and benefits (or profitability) of the various mechanisms for capturing and utilizing available energy to build biomass and do work.

Peak oil

Political implications "[T]he escalation of social protest and political instability around the world is causally related to the unstoppable thermodynamics of global hydrocarbon energy decline and its interconnected environmental and economic consequences."

Energy backed credit One 2020 analysis concluded that a reduction of GDP in advanced economies is likely when the economy can no longer access consumption by adding credit and when there is a shift towards lower quality and more costly energy and resources. The analysis predicts decreasing energy quality and increasing energy costs in the 21st century.

Worked examples

Example 1 — a first encounter with Thermoeconomics

Start with the simplest possible case. Write down what Thermoeconomics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thermoeconomics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thermoeconomics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thermoeconomics

In research
Thermoeconomics appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Thermoeconomics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Thermoeconomics is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ecological economics, Industrial ecology, Schools of economic thought, so understanding it makes those chapters shorter.
In everyday life
Look for Thermoeconomics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Thermoeconomics in simple terms?

Thermoeconomics, also referred to as bioeconomics or biophysical economics, is a school of heterodox economics that applies the laws of thermodynamics to economic theory. Thermoeconomics applies statistical mechanics to economic value.

Why does Thermoeconomics matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Thermoeconomics?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Thermoeconomics.
