Daylight saving time consists of a practice that allows watches, and therefore times, to be advanced by one hour during spring and summer, every year.
One of the main benefits of switching from standard to daylight savings time is optimization and energy savings across the country. Although, many people believe that this economy does not exist, we can confirm through the article "Do We Really Need Daylight Saving Time?" that "A study by the U.S. Department of Transportation showed that the country’s electricity usage is cut by 1 percent each day because of daylight saving time." As spring and summer last six months, saving 1% of energy per day promotes great savings when using daylight savings time.
This energy saving promotes a reduction in pollution, since less burning of fossil fuels is necessary to supply a country's energy needs. In addition, the daylight Saving Time allows for a better use of the day, allowing people to dedicate themselves to some daytime activity with more time available. In this regard, the article states that "[...] people could work longer, and when work was done it was still bright enough to run errands and stimulate the economy. The added daylight also meant more exposure to vitamin D and the added time for people to exercise outdoors. "
Accordingly, we can conclude that the change from standard time to daylight saving time is beneficial even with the controversial energy savings that this change promotes, since daylight saving time allows better use of the daytime period.
