has daylight savings time ever actually saved energy?

Answer 1

DST has been saving Energy all over the world since Ben Franklin thought of it in France in 1787. He was walking down the street and saw a bunch of shops in the financial district with candles burning from people working late. He thought that if they had a couple extra hours of daylight, they could save a bunch of money on oil for their lamps.

There have been studies to suggest that the US can save 1% per day during daylight savings time and across the US this can result in a large amount of money.

Answer 2

Yes, it works. It saves ~1% energy use PER HOUSEHOLD PER DAY (which is an enormous amount when you multiply by the number of houses and the number of DST days in the year).

Also, it is wrong to say that the savings are offset by the extra energy usage in the morning. Peak energy usage is between 3 and 6 PM in typical North American cities. This is when the most people are awake and busy doing something.
