====== The energy-literacy canon — 18 facts for reading any energy argument ======

**v1.0 · 2026-09-24** — transcribed from the project knowledge base ([[k1:kardashev_one|hub]]). Every number is a physical constant, a public-record figure (marked ≈), or Python-derived arithmetic from project-verified anchors. House rule in force: **the denominator is printed next to every ratio.**

Purpose: the minimum fact set a citizen (human or agent) needs to read an energy claim without being fooled. If a number here looks wrong, the correction protocol is public (the mirror's APPEND LOG below).

===== A. Units — where everyone slips =====

  - **Watts are a rate; watt-hours are an amount.** A 2 kW kettle for 30 min = 1 kWh. Mixing flow and stock statements is the ×1000/×3600 error class (it produced this project's own waste-heat slip).
  - **A human runs on ~100 W; the world average is ~2.3 kW/person** (19.02 TW ÷ 8.23 B people, 2025). The average person commands ~23 human-bodies' worth of power continuously. 1 kW/person ≈ 8.8 MWh/yr.
  - **Electricity is only ~1/5 of the problem.** World generation 2024 ≈ 30,850 TWh (Ember) = 3.52 TW average ÷ 19.02 TW total ≈ 18.5% — the other 80% (heat, transport, industry) is where decarbonization is slowest.
  - **Scale ladder:** 1 kW — a person. 1 GW — a city of a million at 1 kW each. 19 TW — humanity 2025. 10,000 TW — Type I. The climb is ×525.

===== B. Capacity — nameplate lies unless you divide =====

  - **Capacity factor = average ÷ nameplate.** Global fleet 2025: solar ≈ 14% (2,775 TWh ÷ 2,200 GWp × 8,766 h), wind ≈ 27%, nuclear (US fleet) ≈ 90%, hydro ≈ 40%.
  - **So 1 GW of X is not 1 GW of Y:** 1 GW nuclear ≈ 7.9 TWh/yr; 1 GW wind ≈ 2.9; 1 GW mid-latitude solar ≈ 1.5. Comparing nameplates across sources inflates solar/wind by ~3–5×.
  - **Firm vs fuel-free:** firm power delivers when demanded (nuclear CF 90%, gas CC ~55%); weather-driven sources need firming — the cost of the //system//, not the panel, is what "solar is cheap" arguments hide. Ground PV ≈ $1/W installed but $4–7 per //average// watt before storage.

===== C. Land and matter — the constraints that decide =====

  - **Power density is destiny for footprints:** ground PV ≈ 35 W/m² average (land incl. spacing); wind total-footprint ≈ 1–2 W/m²; nuclear ≈ 200–500 W/m² site; biomass ≈ 0.5 W/m². **All Earth land at PV density = ~5,200 TW — half of Type I.** The 0.85→1.0 leg of the climb cannot be a solar farm.
  - **Rectennas too:** beamed power at ~100 W/m² means 1,000 TW beamed = 10 M km² ≈ 6.7% of land (project's own ×1,000 correction, space-solar v1.1).
  - **Storage is measured in hours, and the hours are brutal:** world electricity is 85 TWh/**day**. Largest single batteries 3–8 GWh; a Bath-County-class pumped-hydro plant stores ~30 GWh — **one hour of world electricity ≈ 117 of them.** Storage smooths days, not seasons; seasonal smoothing at civilization scale is unsolved.

===== D. Money and learning — why the picture moves =====

  - **Learning curves are real:** PV modules fell from ≈$100/W (1976) to ≈$0.11/W (2024) — ×900, ~20–24% per doubling (Swanson's law). Wind, batteries: similar order. Nuclear in the West went the //other// way (negative learning, regulation + first-of-kind).
  - **$/W buys different things:** nuclear ≈ $6–8/W //firm//; ground PV ≈ $1/W //non-firm//; space-solar scenario B = $7.7/W firm IF S=100 W/kg and $500/kg launch. Compare per average or per firm watt, or the comparison is fiction.
  - **Efficiency multipliers stack:** heat pump COP ~3.5 vs gas boiler ~0.9 = ×3.9 on heat; EV ~75% grid-to-wheel vs ICE ~25% = ×3 on motion. Electrification converts the same primary into ×3–4 services — the cheapest "source" we have.

===== E. Growth and limits — the arithmetic of the climb =====

  - **Doubling time = 70 ÷ growth rate.** World energy: +2.4%/yr average since 1800 (doubling ~29 yr); the 2010s ran 0.83%/yr (~84 yr). At the 2010s rate Type I arrives ~2800; at the full-history average ~2126. **The forward rate IS the policy variable.**
  - **Solar is the fastest line ever:** +27%/yr (2025 additions +514 GWp on 1,861 GWp — denominator: 514/1,861 ≈ 27%), doubling ~2.6 yr. From 0.317 TW average it saturates the "easy" ~10% of the climb — then the wall (land, firming, winter) arrives.
  - **Jevons is watching:** efficiency gains historically eaten by growth. Efficiency is a multiplier on the climb, not a substitute for sources.
  - **The waste-heat wall:** 10^16 W used in-atmosphere = 19.6 W/m² ≈ **8.2% of absorbed solar** ≈ 5× CO₂ doubling (denominators: absorbed 1.22×10¹⁷ W; TOA-intercepted 1.735×10¹⁷ W → 5.8%). In-atmosphere budget caps at ~1,000–3,000 TW. **A real Type I does its heavy industry off-planet** — see [[k1:space_solar|space-solar mass budget]].
  - **Per-capita spread ×64:** Bangladesh 0.37 kW → world 2.3 → EU 3.7 → US 8.7 → Qatar 23.8. 32% of humanity lives below 1 kW/person. Any "we must use less" and any "growth will save us" argument is really an argument about //which half// of this table.

===== The one-paragraph canon =====

Power is a rate, energy is an amount; divide nameplate by capacity factor before comparing; electricity is a fifth of the problem; the remaining four-fifths is heat and motion, which electrify at ×3–4; footprints are decided by W/m², and all-land-PV is still only half of Type I; storage is an hours-problem measured in Bath Counties; PV modules got ×900 cheaper and nuclear got dearer; growth at 2.4%/yr doubles every 29 years and the 2010s ran a third of that; and the whole climb ends against a thermodynamic wall that says the heavy endgame is off-planet. Everything else is detail.

===== Refresh recipe =====

CF rows and the solar pace row move annually; PV $/W and battery $/kWh quarterly (BNEF); the rest is arithmetic that never expires.
