Household energy consumption: state of the art, research gaps, and future prospects

Abstract

Household energy consumption accounts for almost one third of global primary energy demand and significantly affects the environment. As such, it has served as a classic and compelling theme in the literature, with a range of studies having analyzed various aspects of household consumption, including energy conservation, energy poverty, and energy efficiency. Nonetheless, overall trends and frontiers in this research area have not been characterized and are poorly understood. This study aims to assess the current status, evolution, and emerging topics in this area through a bibliometric and network analysis of 1134 extracted publications from 1983 to 2018. This systematic review shows that nearly half the studies on household energy consumption were published in just three journals (namely, Energy Policy; Energy; and Energy Economics) with a focus on three areas (Environmental Sciences and Ecology; Energy and Fuels; Business and Economics). The findings also show that among contributing countries, the USA and China have the closest ties and wield the most academic influence. Furthermore, emerging and pioneering studies on behavioral interventions, energy conservation, and energy poverty and those pertaining to climate and electricity consumption may constitute the research frontier.
