Rationale and original idea The main purpose of Daylight Saving Time called "Summer Time" in many places in the world is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening.
Countries have different change dates. Glide your cursor over the map to see how changing the clocks affects different latitudes. If you live near the equator, day and night are nearly the same length 12 hours. But elsewhere on Earth, there is much more daylight in the summer than in the winter.
The closer you live to the North or South Pole, the longer the period of daylight in the summer. Thus, Daylight Saving Time Summer Time is usually not helpful in the tropics, and countries near the equator generally do not change their clocks.
A poll conducted by the U. Indeed, some say that the primary reason that Daylight Saving Time is a part of many societies is simply because people like to enjoy long summer evenings, and that reasons such as energy conservation are merely rationalizations.
According to some sources, DST saves energy. Studies done by the U. Department of Transportation in showed that Daylight Saving Time trims the entire country's electricity usage by a small but significant amount, about one percent each day, because less electricity is used for lighting and appliances.
Similarly, in New Zealand, power companies have found that power usage decreases 3. In the first week, peak evening consumption commonly drops around five percent.
The rationale behind the study of DST-related energy savings was that energy use and the demand for electricity for lighting homes is directly related to the times when people go to bed at night and rise in the morning. In the average home, 25 percent of electricity was used for lighting and small appliances, such as TVs and stereos.
A good percentage of energy consumed by lighting and appliances occurred in the evening when families were home. By moving the clock ahead one hour, the amount of electricity consumed each day decreased. In the summer, people who rose before the sun rises used more energy in the morning than if DST were not in effect.
However, although 70 percent of Americans rose before 7: In the winter, the afternoon Daylight Saving Time advantage is offset for many people and businesses by the morning's need for more lighting. In spring and fall, the advantage is generally less than one hour.Classical and Operant Conditioning Essay Words | 4 Pages.
