But, starting Monday, March 10, make sure to have all of your watches and clocks — don’t forget your automobile clocks — straightened out so you don’t oversleep for work.
According to the U.S. Department of Transportation, which is the authority over time zone observances, DST is preferred because Americans enjoy more light in the evenings to enjoy outdoor activities, it saves energy by trimming the entire country’s electricity usage by less than one percent each day, and studies have found that it is good for public health and safety.
However, research from the University of California showed that having the entire state to switch to DST would cost Indiana households about $8.6 million in electricity bills each year. The study also estimated social costs of increased pollution emissions that ranged from $1.6 to $5.3 million per year. The study also suggested the reduced cost of lighting in the afternoons during DST would be offset by higher air-conditioning costs on hot afternoons and increased heating costs on cool mornings.
Under the Energy Policy Act of 2005, DST is observed from the second Sunday in March to the first Sunday in November.
