**F1 — Tier.** T2 (contested — energetically informed economic analysis has empirical support, but the strong claim that economic value is thermodynamically determined is not established). Uncertainty flag: The relationship between energy and economic value is correlation, not proven causation.

**F2 — Sources.** 
- Soddy, F. (1926). Wealth, Virtual Wealth and Debt. George Allen & Unwin.
- Georgescu-Roegen, N. (1971). The Entropy Law and the Economic Process. Harvard University Press.
- Odum, H.T. (1971). Environment, Power, and Society. Wiley-Interscience.
- Odum, H.T. & Odum, E.C. (1976). Energy Basis for Man and Nature. 2nd ed. 1981. McGraw-Hill.
- Ayres, R.U. (1998). “Eco-thermodynamics: economics and the second law.” Ecological Economics, 26(2), 189–209.
- Lotka, A.J. (1922). “Contribution to the energetics of evolution.” Proceedings of the National Academy of Sciences, 8(6), 147–151.

**F3 — Domains.** Economics (energy cost of production), ecology (trophic energy flows, maximum power principle), industrial ecology (embodied energy, emergy).

**F4 — Scale.** Single process (~10⁰ m) → global economy (~10⁷ m).

**F5 — Falsifier.** Durable economic wealth with zero exergy throughput — a good, service, or asset that maintains or increases its value indefinitely with no energy input. If economic value can be created and sustained without energetic cost, the thermoeconomic thesis fails.

**F6 — Rival (strongest form).** Economic value is socially constructed, not energetically determined. The correlation between energy use and economic output reflects industrial-era technology, not a fundamental law. Information goods, software, and financial instruments have near-zero marginal energy cost but high economic value. Georgescu-Roegen’s entropy law argument conflates physical entropy with economic scarcity — they are not the same concept. (Solow 1974 American Economic Review review of Georgescu-Roegen; Stern 2011 Energy Economics on decoupling.)

**F7 — Independence.** HIGH. Soddy (chemistry/ economics, Oxford), Georgescu-Roegen (economics, Vanderbilt), H.T. Odum (ecology, U. Florida), Ayres (industrial ecology, INSEAD), Lotka (mathematical biology, Johns Hopkins) — five independent programs across chemistry, economics, ecology, and biology. No shared institutional lineage.

**F8 — Pattern type.** Energetic.

**F9 — Maps.** A2 (thermodynamic/computational), A4 (biosphere-ecosphere).
