It’s that time of year again. As we turned back our clocks on November 4th, the prospect of long, dark, and dreary winter evenings caused many of us to ask once again – why is it exactly that we use Daylight Saving Time (DST)?
It seems that ever since this practice began, debate has raged on the potential benefits and disadvantages of the bi-annual ritual. We increasingly hear arguments advocating for extending DST year-round, mostly on an environmental basis: if DST saves energy, why not make it permanent, and thereby reduce national GHG emissions?
The paper “Is There a Case for Extending Daylight Saving Time” takes a closer look at this reasoning. We examine how the complex interactions between electricity use and daylight hours makes it challenging to determine electricity savings from year round DST, and explain why the applied energy mix is in fact the more important factor in terms of GHG emissions.
