Summer Time and Electricity Conservation: The Israeli Case

Abstract

Summer Time (ST) refers to the practice of advancing the clock during the summer (commonly by one hour) in order to adjust it to changes of sunrise and sunset times at that period. Conventionally, ST is expected to accomplish three objectives: To reduce electricity consumption during dark evening hours. To reduce use of air conditioning systems during the morning. This effect, the result of an additional cool hour, is partially offset by an increased consumption of electricity for lighting during very early morning hours. To increase productivity (particularly in the industrial sectors that are not air-conditioned) following an additional cool hour in the morning.
