LED lighting in Indonesian residential electricity sector: A user's behavior analysis for energy saving

Abstract

Abstract Residential electricity demand can be influenced by the behavior of users. Therefore, it is essential to know users’ behaviors to reduce electricity consumption or for energy saving. This research aims to analyze users’ behaviors concerning the use of light-emitting diodes (LED) lamps in the residential sector in Makassar, Indonesia. Moreover, the drivers of users’ behaviors in terms of usage and habitual behavior are also identified by two composed regression models. Some options for both models were compared by using statistical tests to get better models. A questionnaire was developed, and the survey was done on respondents that have 900 VA and greater of installed power capacity in their homes to get data for analysis. The main finding of this research shows that the user’s perception of energy saving was quite good. Both proposed models, namely LED usage model and habit model, were well § validated with <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msubsup> <mml:mi>R</mml:mi> <mml:mrow> <mml:mi mathvariant="normal">adj</mml:mi> </mml:mrow> <mml:mn>2</mml:mn> </mml:msubsup> </mml:mrow> </mml:math> a value above 39% for both models. Six considered variables can explain usage behavior better than the habit of users. Among the significance variables, the factor of the technology aspect has the highest effect on the usage of LED lamps and the general perception factor for the user’s habit. Presented results may give useful information in designing programs for consumers in Makassar, such as energy conservation programs or home energy management systems.
