What does Daylight Saving time really Save?

Electricity! Because it's Daylight Saving Time
is this Sunday March 9 (where we "spring forward" our clocks by 1 hour),
how much power is really saved because we get an extra hour of daylight?

Answer: about .5 percent in total electricity per day.

While this might not sound like a lot,
it adds up to electricity savings of 1.3 billion kilowatt-hours, 
or the amount of electricity used by more than 100,000
households for an entire year.

Who would have thought that moving our clocks would
really save us on our Hydro bill? ;)
