Daylight savings time has been with us through most of our history. The familiar reason is that we do this because it helps us save energy and farmers like losing an hour of sleep when they get up to milk the cows. Most countries participate in a time change based on the premise of energy reduction, but there are a few rebels who get along just fine without twisting their clocks into knots. If you have noticed that this is a global bi-annual pastime, you may think that there is some real evidence and study to prove that this whole time change thing is really worth all the wacky trouble.
In the U.S.A., the law is part of the Energy Policy Act that even has some allowance of penalty for not jumping off the bridge like everyone else, except for Arizona and a handful of others. This whole idea of daylight savings was made law back in the early 1900’s, and the days for springing forward and falling back were shuffled around and toyed with until the late 70’s and again in 2005. Each time the government changes the date for a time change, they have to produce a report that qualifies their decision.
I could not find those reports but I did find other studies, like this one here, that show how ineffective the whole DLS theory really is. The most interesting one I came across was from here, where the daylight savings mess is really about making money off of you. There is more evidence that dumblight savings actually increases your carbon emissions and causes more pollution than having one unadulterated time.
I guess the environment doesn’t really lobby for itself very well. People tried to tell the sun when to rise and when the morning should come, but it didn’t listen. I think we should follow the sun on this one and look for a brighter day without the clock mangling.
