Energy efficiency and rebound effect for household gas consumption: evidence from Ankara

Yılmaz, Zehra İlknur
Increasing energy demand and concerns about energy security and climate change have led to energy efficiency to become one of the important energy policy objectives in many countries. It is conceived that energy efficiency improvements will decrease energy consumption and CO2 emissions. However, actual efficiency savings are often less than projected savings because of consumer behavior. This concept is known as the rebound effect which is an important factor to be considered while estimating results of energy policy measures related to energy efficiency. While the rebound effect has been studied for developed countries, studies in developing countries are limited. Moreover, most studies have been focused only on economic analysis by neglecting social factors. In this study, direct rebound effect for space heating targeting households in Ankara is studied by using primary and secondary data related to economic and social indicators for energy efficiency applications in buildings. Moreover, the demographic, dwelling characteristics and behavior factors that have an effect on gas consumption are explored and concomitantly inferences and recommendations are made to policymakers in Turkey.
