Résumé
Technological advancements spawn products that tend to be useful when placed in the appropriate hands. Here we investigated whether potential benefits of owning a feedback device were driven by individual differences in environmental values (i.e. biospherism), or whether the device alone is sufficient to reduce energy over time. We examined a total of 276 households, 138 equipped with a feedback device formed our treatment group, and 138 control households selected from a wider pool of households (+2000) based on their similarity to the treatment households, according to a statistical matching procedure. The results indicated that individuals with low biospheric values fail to decrease their electricity expenditure when paired with a feedback device. Conversely, highly biospheric individuals do engage in more pro-environmental behaviour when they receive feedback, but only when they have owned the device for about three years or more. We obtained additional insights, by focusing on differences within the treatment group that suggest, once again, that only highly biospheric individuals who owned the device for over three years successfully implement changes in the household. Overall, these results indicate that feedback devices such as smart meters can be important tools in achieving energy reductions only when paired with environmentally concerned individuals. Given the current trend towards increased feedback technology, policy implications for decision makers are discussed.
