Early Daylight Savings Equals Energy Savings of .05%

Early daylight savings time starts on Sunday, three weeks early, as dictated by Bush’s 2005 Energy Policy Act. However, even as airlines and businesses struggle to adjust their computer and scheduling systems to accommodate the time change, turns out there’s precious little evidence that the extra hour of daylight will save any significant amount of energy.

A study by the California Energy Commission, released last month, found that if people maintain their daily schedules then spring and fall daylight savings time extension would probably cause a 2 to 5% drop in the evening while morning electricity use would grow some, but probably not enough to offset evening savings. “The net effect is small and uncertain: a best guess of total net energy savings is on the order of ˝ of 1%, but savings could just as well be zero.”

In fact, the researchers go on to say there’s a 25% chance that the early time change will actually increase electricity use, and that they’re 95% confident that the energy savings range from a potential increase of 1.1% to a potential decrease of 2.2%.

Part of the reason for the low energy savings may be because of an increase early morning electricity use. Sunrise will move from about 6:15 a.m. to 7:15 a.m., meaning students and early-morning workers may need to use more lights while getting ready. Schools and coffee shops and other places that open in the early morning will also need more electric lights to function. As an example of how early daylight savings time can backfire, take the case of Australia: they instituted an early daylight savings time for the 2000 Olympics, and saw an immediate spike in early morning electricity use, resulting in an overall energy increase and higher electricity bills.

This is a typical example of leadership by symbolism. Instead of real reform to promote racial and social equality we give a national holiday to Martin Luther King. Instead of real drug education that educates people on responsible drug use, we add mandatory sentencing to addicts who sell arbitrarily banned drugs to bankroll their addiction to drugs that are way overpriced due to drug laws and the resultant profiteering.
Instead of reexamination of our foreign policy we enact the Patriot Act - to respond to the problems that our foreign policy causes with acts of retribution and vengeance from its victims.

Another example of our elected idiots thinking for themselves and not us; as they promised they would do when they were trying to get elected. What ever happened to voting on stuff like this seems that more and more is being shoved down our throats without us ever getting to vote or even state our side of it!!

The research and the article ought to be be required reading by Ed Markey, the congressman from Mass. who had the grand idea of inserting this change into the energy bill. He's still going around touting the so-called savings that will supposedly be the result of this dubious and annoyingly unnecessary change, current evidence to the contrary. Of course getting a congressman to admit he might have been wrong about his own legislation would cause the earth to stop spinning.....

I'm not instituting DST in my home this year - or ever again. Until we do away with this silly annoyance, I will give all times to other people in real time/DST. I encourage everyone else not to play along with this farce. I knew it wouldn't be anything but a pain in the @$$.
