Abstract: This paper looks at the potential systematic variation in energy savings resulting from daylight saving time(DST)in a number of geographic areas varying in latitude ranging from Northern to Southern Europe. We are using the same econometric specification and estimation method for a consistent dataset of electricity load covering 35 countries in Europe. Thus our results provide a comprehensive set of consistent and comparable estimates of the DST effect. The average treatment effect results obtained from difference-in-difference regression for 46 electricity load zones ranges from zero in northern most parts of Norway and Sweden to more than 2.5 % in a number of locations. We find some evidence that energy savings from DST decreases with latitude, and especially for homogeneous groups of countries. The diversity in estimated effects cuts across geographical, cultural and economic factors.
