John J. Miller on Daylight Savings Time on National Review Online
Can we please slow down and get something straight? There is simply no way to "save daylight." People can spin the hands of their clocks like roulette wheels, but come Monday here in Washington, D.C., we're still going to have sunshine for about 12 hours and 45 minutes. The sun can rise at a time of day we call dawn or Howdy Doody Time or whatever — but the stubborn facts of astronomy are at work here and they can't be wished away.
Daylight saving time - Wikipedia, the free encyclopedia
DST is not universally accepted; many localities do not observe it. Opponents claim that there's not enough benefit to justify needing to adjust clocks twice per year. The disruption in sleep patterns associated with setting clocks forward, and thereby "losing" an hour, correlates with a spike in the number of severe auto accidents, as well as emotional trauma and lost productivity as tired workers adjust to the schedule change.There were some good comments made in response to this Slashdot article.
There is also a question whether the savings in lighting costs (people just home from work don't turn on the electric lights because there is enough sunlight through the windows) justifies the increase in summertime air conditioning costs (people home from work do turn up the air conditioning during the late-afternoon peak load times, because it's still warm outside). When air conditioning was not widely available, the change did save energy; however, air conditioning is much more widespread now than it was several decades ago.
Man, I could use a nap right now.
