Bedtime for most of us is late evening through the year. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home. By moving the clock ahead one hour, we can cut the amount of electricity we consume each day. Studies done by the U.S. Department of Transportation show that we trim the entire country's electricity usage by about one percent EACH DAY with Daylight Saving Time. This means that less electricity would be used for lighting and appliances late in the day.
Most people plan outdoor activities in the extra daylight hours.
When we are not at home, we don't turn on the appliances and lights. Daylight Saving Time also saves a small amount of energy in the morning when we rise. Studies show that 70 percent of all Americans rise prior to 7 a.m. during the work week. During the summer months, sunrise is very early in the morning, so most people will wake after the sun rises. Because the sun is up, we will turn on fewer lights in our homes.
