Daylight Savings Time saves daylight for the evening but does not save energy. That seems to be the consensus, even though proponents of DST may claim its energy-saving appeal.
On Sunday morning we go back to regular time. Remember to set your clocks when you go to bed Saturday. (Fall back.)
DST has its appeal. The Sunshine Protection Act introduced in Congress earlier this year looks at year-round on DST. The bill was read twice and referred to the Committee on Commerce, Science, and Transportation.
If electric lights are not being used as much in the evening, when there is more sunlight during DST, is that an energy-saver? One study says any energy change is negligible, with, “…a trade-off between reducing demand for lighting and increasing demand for heating and cooling.” (Source)
Take your pick on how your want to use power.
The nation may go to a universal DST anyway if you look at past legislation. In 1966, President Johnson signed the Uniform Time Act that set DST for the last Sunday of April until the last Sunday of October. In 1986 the law was changed to make it begin the first Sunday in April. In 2005 the start date became the second Sunday of March and ended it a week later, first Sunday in November.
See a trend?
Since we are an energy site we should note that one report says that gasoline emissions go up during DST because more people are out driving. Actually, gasoline outlets were in favor of longer DST. (Source)
That is a different side of the energy equation.
