Daylight Saving Time = Global Warming?

Imagine this. Something that was started without fully studying what the long term effects would be, has turned out to have some unexpected results. Daylight Saving Time was created to save energy, but it actually does just the opposite, and, contributes to the dreaded “global warming”. It’s all explained below. Don’t forget to spring forward  this weekend!!

Daylight saving time! What is it good for?

Not much, say two University of California, Santa Barbara researchers who conclude that setting the clock forward actually ends up using more energy, not less.

“I’ve never had a paper with such a clear and unambiguous finding as this,” lead researcher Matthew Kotchen told the Wall Street Journal.

One big argument for daylight saving time, which began as a temporary measure during World War I and gradually became a yearly fixture in most of the U.S., has always been that more daylight in the afternoon reduces the need for artificial lighting, thus cutting down on energy costs.

That’s the main reason why Congress, in the 2005 Energy Policy Act, extended daylight saving time to begin the second Sunday in March and end the first Sunday in November. Standard time is now not standard at all, covering only one-third of the calendar year.

But, as Kotchen, an economics professor, and doctoral student Laura Grant explained to the National Bureau of Economic Research last month, that’s bunk.

“There is surprisingly little evidence that DST actually saves energy,” they state in the abstract to their draft paper. “Our main finding is that — contrary to the policy’s intent — DST increases residential electricity demand.”

The rest is here.
