Studies show daylight savings doesn't save energy

The daylight savings ritual of turning clocks back in the fall, forward in the spring was conjured during World War I to save energy. Seems reasonable. Maybe it worked back then. But a recent study shows it doesn't seem to work these days. A study in Indiana found, "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." (Climate Progress)

The Indiana study confirms what an Australian study found last year. (via Climate Progress)

Combine that with news last week that the Spring daylight savings change
causes a spike in heart attacks, Pound360 wonder if it isn't time to call an end to the ritual.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
