|Abstract:||Daylight saving time energy savings have always represented a contentious topic requiring empirical
evidence for, or against. Unfortunately, as the conclusions are miscellaneous—without an evident
pattern of heterogeneity occurrence—insisting on particular case studies and narrative literature reviews
seems to be insufficient. In this thesis, set of various studies concerning the effect of daylight saving
time on energy savings is examined through meta-regression analysis to provide an accurate estimate of
the effect corrected from publication bias, and other distorting and deflecting effects. We find that the
mean reported estimate in the literature suggests 0.3% energy savings; our results suggest no signs of
publication bias. On the contrary, the study design turned to be a substantial determinant of the primary
literature findings. The thesis provides a unique overview for this is the first meta-analysis conducted on
the daylight saving time energy savings.
