Daylight Saving Time is four weeks longer since 2007 due to the passage of the Energy Policy Act in 2005.

Unfortunately, it is exceedingly difficult to determine energy savings from Daylight Saving Time and based on a variety of factors, it is possible that little or no energy is saved by Daylight Saving Time.
