Social Influence and Economic Intervention Policies that Reduce Energy Consumption:
Evidence from Air-conditioning Use
Constantine Spandagos, Erik Baark and Masaru Yarime
|
In 2020, air conditioners consumed 31% of total electricity use in Hong Kong (EMSD, 2022) and electricity generation accounted for 60.4 percent of the city’s greenhouse gas emissions (EPD, 2022). Therefore, policies that encourage energy savings in air-conditioner use are critical if the city wishes to achieve carbon neutrality. Nevertheless, successful policy interventions must be cost-effective and socially acceptable to incentivize energy-saving behaviors (Cialdini, 2007). This bulletin introduces a paper by Spandagos (2021) that identifies factors that determine the effectiveness of various policy interventions designed to curb residential air-conditioning energy consumption through a case study set in Hong Kong.
