Daylight Saving Time Wastes Energy

An anonymous reader writes "With the time approaching when we'll be changing our clocks again, the Wall Street Journal is running a timely article on a study done by a UC-Santa Barbara economics professor and a Ph.D. student. The study unambiguously concludes that Daylight Saving Time not only doesn't save any energy, it actually wastes energy and costs more. The study used energy company records from Indiana before and after that state mandated DST for all of its counties, and calculated that the switch cost Indiana citizens $8.6M per year. 'I've never had a paper with such a clear and unambiguous finding as this,' the professor said."

    Adjust business hours periodically. Don't change the freakin' clock and have an hour go missing every 6 months. It didn't even make sense when we were still hand plowing. It certainly doesn't now!!!

    So people are really so stuck in their ways ...

    No, people are not stuck in their ways. If it was easier to keep the clocks the same throughout the year, don't you think it would have been kept? It was tried in the 1970's and many children were killed on the roads walking to school, despite reflective bands being handed out, so it was changed back.

    It's much easier if the clocks are changed. As one small example, imagine what a bus/train timetable would be like if the times changed rather than the clocks.

    So we have to putt an if statement in our code, or do a lookup on timezones. No biggy. Anyway, most DBs/OS's will handle ST and TZs.
