A new study suggests that Daylight Savings Time is actually worse for the environment. Up yours, Bob Hughes. Now can we finally put this debate to rest?

"There is a reason we continue to get daylight savings under the rubric of energy conservation because as a policy, it costs individual consumers nothing and asks them to conserve nothing. So it's wildly popular," he says.

"Unfortunately, it's entirely ineffective."

Previous studies on daylight savings have had similar findings. But most have been based on simulation models, not concrete data. An exception was a study on the extension of daylight savings in two Australian territories for the 2000 Summer Olympic Games, which showed more electricity used.
