What are the costs and benefits of daylight saving time?
Kožušková, Kateřina ; Bartoň, Petr (advisor) ; Schwarz, Jiří (referee)
Daylight saving time (DST) was implemented with purpose to maximize use of daylight and thereby reduce electricity consumption used for lighting. This policy would primarily affect energetics, however its influence was shown in many other areas. The thesis contains general assumptions of daylight saving time impact on electricity consumption and the main goal of the thesis is to identify with the natural experiment whether the extension of daylight saving time till the end of October occuring in Czech republic in 1996, led to savings of electricity consumption. Observed period is September and October between years 1993 and 1998. First, the difference in consumption between days with DST and without DST is investigated. On days with DST the consumption was lower than on days without DST. The two other regression analysis are devoted to the effect of the introduction of DST in October. First, the analysis included both observed months, the effect of extending daylight saving time however was not demonstrated. Further, October as itself is analyzed. October consumption was reduced by approximately 2,4 % in three years after the introducion of DST, compared with three previous years, when DST was not implement in this month.
