Core Idea

Efficiency rebound is the graded offset that occurs when an efficiency gain reduces both resource use and effective cost per unit of service, then the cheaper service attracts more activity. Expected resource saving assumes fixed volume; realized saving must be recomputed after volume responds.

Partial rebound preserves some saving. Full rebound cancels it. More-than-full rebound raises total resource use and is the strong Jevons-paradox region.

Broad Use

  • Energy — efficient heating, lighting, and appliances stimulate use.
  • Transport — faster or more fuel-efficient travel lowers generalized cost and induces trips.
  • Water — efficient irrigation can expand irrigated area or crop intensity.
  • Computing — cheaper computation unlocks new applications and workload.

Clarity

The prime separates the whole rebound spectrum from Jevons backfire and from the catalog's unrelated suppressor-withdrawal Rebound Effect.

Parents (3) — more general patterns this builds on

  • Efficiency Rebound is a kind of Counterresponse Offset Prime

    Efficiency rebound is a counterresponse offset specialized to demand expansion induced by an efficiency-driven fall in effective unit cost.

  • Efficiency Rebound presupposes Efficiency Prime

    The rebound begins with a genuine efficiency gain that reduces resources required per unit of service.

  • Efficiency Rebound presupposes, typical Price Elasticity Prime

    The magnitude of efficiency rebound is typically governed by how strongly activity volume responds to the resulting fall in effective price.

Children (2) — more specific cases that build on this

  • Rebound Emissions Domain-specific is a kind of Efficiency Rebound

    Rebound Emissions is Efficiency Rebound specialized to carbon intensity, activity volume, and aggregate greenhouse-gas outcomes.

  • Jevons Paradox Prime is a kind of Efficiency Rebound

    Jevons Paradox is the more-than-full Efficiency Rebound region in which demand expansion reverses the sign and raises total resource use.

Not to Be Confused With

  • Jevons Paradox is the more-than-100-percent child in which total resource use rises.
  • Counterresponse Offset is the broader family including safety and insurance responses not caused by efficiency.
  • Withdrawal Rebound (legacy alias rebound_effect) is compensator-lag overshoot after removal of a suppressor, not demand expansion after efficiency.
