Simulate how efficiency improvements can increase total resource consumption through the rebound effect.
In 1865, economist William Stanley Jevons observed that improved steam-engine efficiency led to more coal consumption, not less. When a resource becomes cheaper to use, demand often rises enough to overwhelm the savings — this is the rebound effect. When the rebound is large enough to exceed 100 % of savings, total consumption rises above its starting point: the Jevons Paradox.
How much more efficient is the new technology? 50 % means the same service uses half the resource.
By what percentage does demand increase for every 1 % price drop? 0 = no rebound, 1 = proportional, >1 = amplified.
