Daylight saving time

There are many ideas floating around the much talked about launching of daylight saving time in the country. Responsible government sources are claiming that there would be about 250 - 300 MW electricity saved leading to a curtailment in load shedding. But the enthusiasm may turn into despair. The following factors will stand in the way of fulfilling the desired goal.
-In most of the offices and business establishments, there is no provision for using daylight as those are designed and constructed in a way that only artificial i.e. electric lights can be used. And many of buildings are normally centrally air-conditioned and consume more electricity during daytime because of higher ambient temperature.
- Many establishments like garment factories and other production industries, petrol stations etc. that work round the clock, will contribute minimally to DST.
- In urban areas all social programmes normally take place during night time and this DST will not change this custom.
In rural areas, people normally follow the sun to know the time. So, DST will fail to dictate them to change their habits.
- Amount of electricity consumed by all the mosques throughout the country is not negligible and that will remain unaffected as prayer timings also follow the sun rising and setting times.
The targeted goal of electricity saving can, at least partly, be achieved just by following different office timings in summer and winter. It is difficult to understand why the government is not choosing this simple way.
