Saving daylight

In light (forgive the pun) of the recent switch to Daylight-Saving Time, I offer the following editorial, originally published in 2007:
This weekend, clocks across the country will "spring forward" earlier than usual, as we observe daylight-saving time in March, rather than April, in compliance with the Energy Policy Act of 2005.

It was 100 years ago that William Willett, credited as the father of daylight-saving time, published his pamphlet, "The Waste of Daylight," advocating that clocks be changed in spring to take advantage of summer’s late-day sunlight and readjusted in fall.

While Willett’s writing dwells largely on issues of human comfort, it does also discuss the potential energy savings that would result from such a shift _ the same savings that led to the 2005 act that has Americans changing their clocks in March.

Since its introduction in the United States in 1918, daylight-saving time has been the subject of numerous studies.

Does it save energy? How much do…
