It’s that time again where you get to lose an hour of sleep and drive to work in darkness. Why do so many do it though? The idea that changing your clock backwards, gives an extra hour of daylight, is not true.
If you want to be awake during more of the daytime, you could just wake up earlier. It’s not like changing your clock magically makes a day 25 hours long. There has been much debate about why we keep doing it.
In 2005, George W. Bush signed off on the extension of DST through the Energy Policy Act. Not only did the bill extend the Uniform Time Act of 1966 but it also expanded the period of time change. The new DST starts a month earlier and ends a month later.
The argument of supporters of DST is that energy is saved by not needing to turn on lights for so long. However, Yale Professor, Matthew Kotchen, released a study showing that there is little evidence supporting daylight savings having a positive effect on energy conservation.
One study from the National Bureau of Economic Research shows that the energy gains are lost through the increase in use of heaters and air conditioners. However, that doesn’t answer why we do it.
In the book, Microeconomics: An Intuitive Approach With Calculus, the author claims that the biggest advocates of the change were retailers and restaurants. There is a business application to allowing your typical nine to five worker an extra hour to consume products. So there it is, you get to be tired tomorrow because retail lobbyists want you to spend more money. To the individual, daylight savings time sucks!
