Extended Daylight Saving Time saves energy?

Will the recent Energy Policy Act of 2005 adopted by USA, actually reduce energy consumption by extending Daylight Saving Times in a year?

"In an attempt to save energy, we sprang forward three weeks early this year, and we'll fall back a week later. A U.S. Department of Energy study predicts that extending daylight saving time will cut our electricity consumption by four-tenths of a percent per day."


"Starting daylight saving a couple of months early doesn't seem to cut energy consumption, as many of its supporters claim."


What are your opinions on this?

I don't see how it would help since all it means is that people who have to wake up early in the morning would be turning on lights instead of people at night.

Although, I guess it's more likely that more people stay up later than get up early.
Well, it depends, I think. In some countries, daylight starts as early as 4AM. So about 2HRS of daylight are wasted in the morning, and after work - it's dark and they use electricity for lighting the house etc for dinner/tv.
That's true. I'm being pretty country-centric lol

What countries have DLT?
I looked it up and they've got a map here of countries in DST: http://en.wikipedia.org/wiki/Daylight_saving_time

Wiki is pretty good - even talks about the DST's effect on Energy Conservation, Economic Effects, Traffic Fatalities etc.

"In 2000 when parts of Australia began DST in late winter, overall electricity consumption did not decrease, but the morning peak load increased."
