THE IDEA

Does efficiency actually save the resource?

Unit savings and behavioral response must be considered together.

Inside this model

Baseline use is 100. Each task consumes 1−e times as much resource, while task count grows by 1+rebound×e. Total use is 100(1−e)(1+rebound×e); rebound is a chosen response coefficient.

Out in the world

A practical use

Cheaper travel per mile may encourage more miles traveled.

WHERE IT BREAKS

A useful lens. Not a universal law.

  • Rebound strength is a scenario assumption, not an estimate of any specific technology or policy.
