Ever heard of the rebound effect?

The effect describes a phenomenon in which savings resulting from efficiency improvements are reduced or even canceled out by an increase in consumption or consumption. The actual savings are therefore lower.

By increasing efficiency, we can succeed in consuming fewer resources and raw materials. However, this is countered by direct and indirect rebound effects: for example, if we save electricity in the household through our behavior and the use of LED lights, this saving is offset by installing more electrical appliances or buying a larger TV. If we invest the rest of the money we save at home in a second or larger car, we are talking about an indirect rebound effect.
