Daylight Saving Time: How Much Energy Does It Really Save?

"Daylight saving time was first used during World War I, as part of an effort in the United States and other warring countries to conserve fuel. In theory, using daylight more efficiently saves fuel and energy because it reduces the nation's need for artificial light."

This fact has long been disputed by politicians and energy experts. Many believe that the extra artificial light needed in dark Daylight Savings mornings cancels out the benefit of brighter evenings. However, a 2008 Department of Energy report to Congress found that Daylight Savings Time does indeed save energy, though not as much as we'd hoped. According to the report, the total energy savings throughout the period of Daylight Saving Time add up to 17 Trillion Btu of primary energy consumption, which is only .02 percent of the country's total use in 2007.
