Tad Patzek, professor emeritus and thermodynamicist focused on energy and earth systems, explains civilization through power flows. He discusses per-capita power as a key variable, why renewables depend on fossil-built supply chains, the nonlinear scaling of overshoot, and how energy, water, and materials constrain our future. Short, math-forward takes on climate, infrastructure fragility, and what true sustainability might require.

INSIGHT

Energy Transitions Have Historically Been Additive

  • Public debate is detached from physics by treating energy systems as instantly reconfigurable.
  • Every historical energy transition was additive: building renewables required more fossil energy to construct their infrastructure.
INSIGHT

Overshoot Scales Roughly As Power Cubed

  • Ecological overshoot scales superlinearly with primary power—roughly the cube—amplifying impacts.
  • Primary power growth drives population and technology, producing a strongly non-linear increase in environmental damage.
INSIGHT

Free Energy Concentration Determines Practical Value

  • Free energy is the convertible portion of energy that does work; concentration and purity matter.
  • Most free energy is used once and dissipated; ~60–70% of fossil primary power becomes rejected heat.
