Digitization and Energy Efficiency: The Case of Shower Heads

Tomberg, Lukas. 2022. “Digitization and Energy Efficiency: The Case of Shower Heads.” SSRN Scholarly Paper. Rochester, NY: Social Science Research Network (SRRN).

Based on an incentivized survey experiment, we estimate the willingness-to-pay (WTP) for three types of efficient shower heads: (i) A “digital” shower head that provides real-time feedback, leading to behavioral changes that may reduce water and energy use. (ii) A “low-flow” shower head that reduces water and energy use by mechanically reducing the water flow. (iii) A low-flow shower head that additionally offers the real-time feedback function. The empirical results show that respondents expect the low-flow shower head to be the most resource conserving, while the WTP is higher for the digital shower head types. Common arguments against the deployment of efficient shower heads, such as a reduced comfort or shower enjoyment, are not corroborated by our survey data, as only a minority agrees with such concerns.
