"Designed (and recently extended) as a measure to save energy in a period of inflated electricity prices, an in-depth University of California study has now shown that DST doesn't save anyone any money at all. In fact, it's costing consumers extra, to the tune of $3.19 in extra utility bills per year."
"Why? Shouldn't they be, well, saving daylight -- and burning fewer light bulbs?
They are, said the study. But while lighting bills were reduced, air-conditioning units had to run more often, because people were home on hot afternoons when they'd otherwise be still at the office. Heaters had to be run on cool mornings, too, when people got up and it was still dark outside."
"in 1976...the National Bureau of Standards found that there was no significant energy savings after the switch."

So we've known for 32 years that DST does no good, now we know that it actually results in wasted energy...why are we still using it?
