DST, Nice Try

The early onset of Daylight Saving Time in the United States this year may have been for naught.

"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.

For example, households may draw less electricity for lights at night, but will use more power in the early in the day as they wake to darker and chillier mornings.

"There might have been a small increase in morning lighting, and a slightly larger decline in evening lighting usage," said a spokeswoman at New Jersey utility Public Service Enterprise Group Inc, but that modest decline will have no impact on its overall sales or earnings.

The U.S. Congress will evaluate the effects of the earlier switch to Daylight Saving Time.
