The rebound effect, also known as Jevons paradox, describes a phenomenon where technological progress or increased efficiency in resource use can lead to an increase in the overall consumption of that resource, rather than a decrease. This occurs because the efficiency gains make the resource cheaper or more accessible, thereby stimulating demand. For example, a more fuel-efficient car might lead individuals to drive more miles, negating some or all of the intended fuel savings.

This effect is not limited to energy resources. It can apply to any resource or service where increased efficiency leads to lower costs or greater convenience. Innovations that make production cheaper or services more readily available can inadvertently encourage greater usage, potentially offsetting the environmental or economic benefits initially anticipated.

Understanding the rebound effect is crucial for policy-making related to resource management and environmental sustainability. Simply aiming for technological efficiency might not be sufficient to achieve conservation goals if the rebound effect is not adequately considered. Policies that aim to curb consumption may need to incorporate measures beyond pure efficiency improvements, such as regulations, taxes, or behavioral incentives. The magnitude of the rebound effect can vary depending on the specific resource, the technology, and the societal context.
