So says this article from Reuters.com:
But other than forcing millions of drowsy American workers and school children into the dark, wintry weather three weeks early, the move appears to have had little impact on power usage.
“We haven’t seen any measurable impact,” said Jason Cuevas, spokesman for Southern Co., one of the nation’s largest power companies, echoing comments from several large utilities.
That may come as no surprise to the Energy Department, which last year predicted only modest energy savings because the benefits of the later daylight hour would be offset.
We also already knew this because they tried it in Australia and it didn’t do much there either.
All it did do was screw with various electronic devices that were pre-programmed to adjust automatically on the old dates. My alarm clock, for example, which sets itself using the U.S. NIST time broadcast. There’s no way that I know of to update the firmware on my clock so it failed to adjust the time forward three weeks ago and I had to set it to the wrong time zone for it to display the time accurately. Then this past weekend it jumped ahead like it was programmed to do and I had to reset it back to the correct time zone.
Personally I hope we drop this experiment next year seeing as it did nothing to help energy savings. Honestly I think it wouldn’t be bad to drop DST altogether, but I’d be happy just going back to the old system so my alarm clock will work like it’s supposed to.
I love that alarm clock.
