Abolish Daylight Savings Time

Yes! Anyone agree? This excerpt is from a story that appeared in the Wall Street Journal about the Daylight Savings Time controversy in Indiana, my home state. The time change was instituted in the '70s to save energy, but according to this study, more energy is lost than saved overall. Why not do away with it and save us all a lot of circadian trauma each year?

 Indiana's change of heart gave University of California- Santa Barbara economics professor Matthew Kotchen and Ph.D. student Laura Grant a unique way to see how the time shift affects energy use. Using more than seven million monthly meter readings from Duke Energy Corp., covering nearly all the households in southern Indiana for three years, they were able to compare energy consumption before and after counties began observing daylight-saving time. Readings from counties that had already adopted daylight-saving time provided a control group that helped them to adjust for changes in weather from one year to the next.

Their finding: Having the entire state switch to daylight-saving time each year, rather than stay on standard time, costs Indiana households an additional $8.6 million in electricity bills. They conclude that the reduced cost of lighting in afternoons during daylight-saving time is more than offset by the higher air-conditioning costs on hot afternoons and increased heating costs on cool mornings.
