The Daylight Saving change: no savings, no point
The US government's plan to boost energy savings by moving Daylight Saving Time forward by three weeks was apparently a waste of time and effort, as the technological foibles Americans experienced failed to give way to any measurable energy savings.
While the change caused no major infrastructure problems in the country, plenty of electronics and computer systems that were designed with the original DST switchover date (first Sunday in April) failed to update. The inconvenience was minor, and the potential savings were great. Or so we were told by the politicians behind the move.
As it turns out, the US Department of Energy (and almost everyone else except members of Congress) was correct when they predicted that there would be little energy savings.
This echoed concerns voiced after a similar experiment was attempted in Australia. Critics pointed out a basic fact: the gains in the morning will be offset by the losses at night, and vice-versa, at both ends of the switch. That appears to be exactly what happened.
