Most homes use about 25 percent of electricity to run lights and small appliances (televisions, stereos, etc.). In most households, energy consumption is the largest in the morning and evening, the theory being school, work and life in general get us out of the house during the day.
By springing forward, the sun sets an hour later, in turn making less demand for evening lighting. Sure, it's a little darker when we rise, but we still get ready for the day in the same amount of time, and probably still use the same amount of (morning) electricity. As the days get longer, we also tend to stay out later, which means less time at home running appliances (other than running the air conditioner, saving energy in the summer is a piece of cake!)
Less energy use adds up fast. In the 70s, the U.S. Department of Transportation studied daylight savings time and electricity usage and saw that use drop by about one percent each day thanks to daylight savings time. In 1974 and 1975, the Department of Transportation noted that just two months of daylight savings time (March and April) saved the equivalent in energy of 10,000 barrels of oil each day, for a total of 600,000 barrels in each of those two years.
So instead of focusing on the hour you lose when you spring forward, think about the energy savings you'll enjoy, all thanks to daylight savings time.
Are you a daylight savings lover?
