How Much Energy Does One Hour of Daylight Save?

My favorite season is DAYLIGHT SAVINGS TIME. I’m looking for information on how the one hour of extra daylight equates to  energy savings .  I know we pull the hour from the other end of the day, but there has to be a huge difference in lighting a home at 6:00 pm versus 6:00 am.

Here is some more info on the history of DST.  

DST was first suggested by Benjamin Franklin in 1784. However, modern DST was proposed by George Vernon Hudson in 1895. Hudson, an entomologist from New Zealand, suggested a two-hour daylight saving shift to the Wellington Philosophical Society. But, DST is credited to William Willett, an English builder. In 1905, Willett proposed that the clock be moved forward during the summer. The proposal went before the House of Commons in February 1908, but was not actually put into practice until 1916, during World War I, when several European countries implemented DST. Thus, “spring forward, fall back” was born. At different periods in history, the amount of the adjustment has been tweaked, but the standard time change is one hour. Also, there have been periods when DST has been used throughout the year, such as in the United States during World War II, from Feb. 3, 1942 until Sept. 30, 1945, when it was deemed “War Time.”
