Daylight Saving Time Costs Nation $1.7 Billion
Since the passage of the Energy Security Act of 2005, which extended daylight saving time (DST) by four weeks—to eight months of the year—DST has become more standard than...standard time. According to the legislation’s co-sponsors, Reps. Edward Markey, D-Mass., and Fred Upton, R-Mich., the daylight saving time extension is supposed to significantly reduce energy usage, as evening sunlight replaces power-generated electricity an additional hour each day.
Unfortunately, this dramatic cut in energy use could very well be illusory, while the costs of daylight saving time are very real.
According to a "back-of-the-envelope calculation" by economist William F. Shughart, the real costs of daylight saving time amounts to $1.7 billion or more annually, read more here.
