It’s time to fall back.
Daylight saving time ends at 2 am tomorrow morning, so set your clocks back one hour. By starting the day a little later, we take advantage of natural sunlight and therefore cut energy consumption. Daylight saving time began almost one hundred years ago, but was actually suggested by none other than Ben Franklin, who satirically remarked that the consumption of candles could be reduced by waking earlier to use morning sunlight. Modern daylight saving time was first proposed by George Vernon Hudson, who was a New Zealand shift worker who wanted more after-hours daylight to participate in his hobby of collecting insects.
Does daylight saving time actually save energy? In 2008, the Department of Energy found that United States electricity consumption decreased by 0.5% per day during daylight saving time, which is enough energy to power about 122,000 average US homes for a year.
