We are to be subjected to another round of
daylight saving time again. Don't forget to reset all your clocks again. Oh, and don't depend on any of your electronics knowing about this change. They were set for the old way, so you get to change some of your clocks 4 times a year.
I don't bother changing any of my clocks, not even my computer clocks. They all stay on STANDARD Time the year around.

BTY, for you mindless drones out there, the sun does not rise and/or set an hour later. It is your clocks that you obediently change because you were told to do so that makes it appear so.
I don't see how going to bed with the sun shining and getting up in the dark saves anything.
(I really do wish they would teach Critial Thinking in school. This would be a much better country to live in. Less war, better programs to make life easier for the citizens. You know, stuff like Health Care instead of Health Insurance. But what do I know?)

The Daylight Saving change: no savings, no point

By Ken Fisher | Published: April 03, 2007 - 11:41AM CT

The US government's plan to boost energy savings by moving Daylight Saving Time forward by three weeks was apparently a waste of time and effort, as the technological foibles Americans experienced failed to give way to any measurable energy savings.

While the change caused no major infrastructure problems in the country, plenty of electronics and computer systems that were designed with the original DST switchover date (first Sunday in April) failed to update. The inconvenience was minor, and the potential savings were great. Or so we were told by the politicians behind the move.

As it turns out, the US Department of Energy (and almost everyone else except members of Congress) was correct when they predicted that there would be little energy savings. This echoed concerns voiced after a similar experiment was attempted in Australia. Critics pointed out a basic fact: the gains in the morning will be offset by the losses at night, and vice-versa, at both ends of the switch. That appears to be exactly what happened.

Daylight Saving Wastes Energy, Study Says
February 27, 2008; Page D1

(See Corrections and Amplifications item below.)

For decades, conventional wisdom has held that daylight-saving time, which begins March 9, reduces energy use. But a unique situation in Indiana provides evidence challenging that view: Springing forward may actually waste energy.

Up until two years ago, only 15 of Indiana's 92 counties set their clocks an hour ahead in the spring and an hour back in the fall. The rest stayed on standard time all year, in part because farmers resisted the prospect of having to work an extra hour in the morning dark. But many residents came to hate falling in and out of sync with businesses and residents in neighboring states and prevailed upon the Indiana Legislature to put the entire state on daylight-saving time beginning in the spring of 2006.

Research on the impact of extending daylight-saving time across Indiana found:
Residential electricity usage increased between 1% and 4%, amounting to $8.6 million a year.
Social costs from increased emissions were estimated at between $1.6 million and $5.3 million per year.
Possible social benefits -- enhanced public health and safety and economic growth -- were not studied.

Indiana's change of heart gave University of California-Santa Barbara economics professor Matthew Kotchen and Ph.D. student Laura Grant a unique way to see how the time shift affects energy use. Using more than seven million monthly meter readings from Duke Energy Corp., covering nearly all the households in southern Indiana for three years, they were able to compare energy consumption before and after counties began observing daylight-saving time. Readings from counties that had already adopted daylight-saving time provided a control group that helped them to adjust for changes in weather from one year to the next.

Their finding: Having the entire state switch to daylight-saving time each year, rather than stay on standard time, costs Indiana households an additional $8.6 million in electricity bills. They conclude that the reduced cost of lighting in afternoons during daylight-saving time is more than offset by the higher air-conditioning costs on hot afternoons and increased heating costs on cool mornings.

Study: Daylight saving boosts energy use

By Dennis Camire, Gannett News Service
WASHINGTON For Benjamin Franklin, daylight saving time was about saving candles and for modern lawmakers, it's about electricity but a recent university study found it might actually cost more energy when the nation resets its clocks Sunday.

Matthew J. Kotchen, a professor of environmental economics at the University of California in Santa Barbara, and Laura E. Grant, a doctoral student in the same field, studied the effects of daylight saving in Indiana, where some counties used it and others did not. The states changed the law two years ago so that all counties now use daylight saving time.

In an interview, Kotchen said using residential electricity bills for Indiana, he and Grant found that daylight saving time reduced electricity use for lighting but that more was used for air conditioning in the summer and heating in the fall than was saved.

Question: Why was the study done?

Answer: Conventional wisdom and the rationale for daylight saving time has been as an energy saving policy.

The point of the study was to actually evaluate whether it does in fact save energy because there has been surprisingly little research that has looked into that question.

What were the results?

We found based on the natural experiment in Indiana that contrary to the conventional wisdom, daylight saving time ... decreases consumption for artificial illumination but increases consumption for heating and cooling.

The magnitude of our estimate (for increased usage) ranged between 1% and 4%.

2. I love it
Instead of it being dark when hubby gets home it is light out. We sit out on the dock and have a glass of wine and or eat dinner outside and watch the sun go down.

3. I remember when they tried it year round claiming energy savings
That should have been the first sign just how stupid Americans are. They actually believed it.

6. Indiana and Arizona share a position at the western edge of their time zone.
For such regions, the salubrious effects of DST are diminished.

9. I'd like to be on Daylight Savings Time all year.
I find the fall change much more difficult to adapt to than the spring. That's just me, though; I'm an early bird and am up before dawn every day anyway.

If we could just pick one, and stick with it, avoiding the twice-a-year disruption to body clocks, I'd be happy.
