The changing of the clocks—which happened once again Sunday morning—is wasteful, unnecessary, and even dangerous, says The Atlantic.
But does Daylight Saving Time actually make much of a difference? Evidence suggests that the answer is no. After the Australian government extended Daylight Saving Time by two months in 2000 in order to accommodate the Sydney Olympic Games, a study at UC Berkeley showed that the move failed to reduce electricity demand at all. More recently, a study of homes in Indiana—a state that adopted Daylight Saving Time only in 2006—showed that the savings from electricity use were negated, and then some, by additional use of air conditioning and heat.
