Daylight Savings probably doesn't save energy

As we all lose an hour of sleep but start to gain some evening daylight this weekend, keep this in mind:

As far as I've found, only one empirical study has been published examining energy use/energy savings associated with the daylight saving adjustment mandated in the Energy Policy Act of 2005.
That study, covering parts of Indiana, concluded in part:

"....there is surprisingly little evidence that D.S.T. actually saves energy. This paper takes advantage of a natural experiment in the state of Indiana to provide the first empirical estimates of D.S.T. effects on electricity consumption in the United States since the mid-1970’s.

Focusing on residential electricity demand, we conduct the first-ever study that uses micro-data on households to estimate an overall D.S.T. effect. The dataset consists of more than 7 million observations on monthly billing data for the vast majority of households in southern Indiana for three years.

Our main finding is that — contrary to the policy’s intent — D.S.T. increases residential electricity demand. "

Here is a link to a brief New York Times article on the subject, which further includes a link to the aforementioned working paper (study).

Also note the following sentence taken from the empirical study: ".... the 2005 Energy Policy Act specifically requires that research be conducted to estimate the actual effects on energy demand, and Congress retains the right to repeal the extensions if the conservation benefits are not realized. "

Hey, D.O.E.: Looking for possibly a quick way to improve (i.e., reduce) national energy use....?
