Did Bush's Changes to Daylight-Saving Time Save Energy?
10 November 2010 2:32 pm
The law of unintended consequences has struck a 2005 law that changed the rules for daylight-saving time, says liberal writer Barron YoungSmith:
There was something unsettling and creepily disproportionate about the idea that Congress couldn't muster the will to improve energy efficiency, so it voted to change time itself—but leave that aside. The rationale for the new daylight savings calendar was that it would reduce energy use by encouraging people to use less electric light, but that assumption hadn't been well tested—and a new study by the National Bureau of Economic Research (NBER) reveals that the policy likely encouraged Americans to use more energy by running heaters and air conditioners more than enough to offset the decreased use of light, and to spend more money doing so.
