Just What is Daylight Saving…Saving?
I’m not a morning person, but I’ll do my part and get up early if it’s in the national interest. The problem is that it may not be, if you believe the working paper that Ryan Kellogg and Hendrick Wolff have written at Berkeley. Their paper, "Does Extending Daylight Saving Time Save Energy?" is HERE. And the answer to their rhetorical question is…no. Parts of Australia tried it in 2000; Kellogg and Wolff found that reduced need for lighting in the evening was almost precisely offset by increased need for lighting in the morning. More HERE. We talked to Kellogg this afternoon: “The response I’ve been getting when talking to people is, ‘Well, why are we doing this if this doesn’t save any energy?’” Congress may have acted just a touch hastily in 2005. The Daylight Saving shift is a few lines in the Energy Policy Act of 2005–which runs 551 pages. The whole thing is HERE. (There will be a quiz on its contents on Monday.) "Daylight Savings"–the "s" at the end is a break from previous law–is Sec. 110 on p. 23. In the meantime, computer clocks may be confused for a few weeks; we posted more HERE. If you have a PC that runs something older than Windows XP*, Service Pack 2, Microsoft has a simple update at http://support.microsoft.com/gp/cp_dst . (*Note to friends: Yes, yes, there was a typo here; I wrote Windows WP instead of XP. I do, however, hold the patent on Windows WP, and will gladly sell it to you.) If you’re a Mac user, go to http://www.apple.com/downloads/ and search for "Daylight Saving." Or just reset the computer’s clock after 2AM Sunday. And if all this leaves you a little ticked off, you’re welcome to sound off below.

“If you have a PC that runs something older than Windows WP, Service Pack 2,”
Is Windows WP the version prior to XP? :-)

The argument is akin to the old joke about the short blanket: if your feet are cold, just cut a couple of inches off the top and sew it to the bottom. I think this is Congress’ thinking on the matter.

Ned, you seem to always answer the questions (or at least point to the right resources!) that seem to percolate to the top of mind!
Just yesterday, a friend asked the exact same question you used as your blog hed!!!
Anyway, I often wonder if the unmeasureable consequences of Daylight Savings Time — the weariness of hundreds of thousands (if not millions) of people who have a tough time adjusting to the time changes, the wasted man-hours to set public clocks & time-keepers like electronic toll booth machines, ATMs, etc. — make the effort worth it as well.
I’m not so much as ticked off by the time shift… But it does seem a bit more onerous this year because the jump in clock adjustment occurs for so many more additional weeks — and as everyone well knows, since we all seem to have an our ever growing list of beloved electronic gizmos, it just means we have THAT many more clocks to change/worry about.
Anyway, great post, Ned. Just one thing….
“Windows WP”??? “XP,” no? Or is there a Windows “word processor” that we have to worry about? OR a Windows “white phospherous?” ;-)

Your blog coalesces my thinking on the entire matter of changing clocks to “take advantage” of Daylight Saving Time: we advance our clocks one hour to have more daylight in the evening, but the mornings aren’t as long as they were because we’ve advanced our clocks one hour to have more daylight in the evening! How this saves energy has always been a puzzle for me, and I’m finally glad to see valid research and an equally valid conclusion that it doesn’t.

Someone else pointed out that with increased daylight hours, people will be driving more. How’s that for energy saving?
