Daylight saving

In the backdrop of scarcity of electricity one may think of daylight saving by advancing clock timing which is in practice in Europe and other countries. Bangladesh is a tropical country where difference of day and night time is not too wide. Sun shines 10 to 12 hours in daytime around the year. As such advancing the clock by an hour will not be useful for us. The concept of day light saving is very much correct and we should utilise it in a customised way but not by advancing clock time. This is not also practised in our neighbouring countries India and Pakistan. We can do it by designing and constructing houses and offices very much accessible to daylight. In contrary to that we see that houses and offices have no access to light, even in secretariat building windows and doors are covered by heavy curtains to make artificial dark and then light it with many unnecessary decorative lights consuming a huge amount of electricity. We should immediately stop this culture to get the benefit of daylight. As day light is immensely available in our country throughout the year we can use solar heater for heating water and solar panels for lighting in the houses and offices during the evening peak. Furthermore, we can change office timing, school timing, shopping mall timing and sliding office timing and derive the benefit of distributed use of electricity. I believe, thus we can have the best use of daylight.
