Day Light Saving time is not very much an old concept for this country. It was introduced few years ago for the first time but was very much opposed by the people and also at that time stats showed that it actually caused loss of more energy that year, so was discontinued for many years. But now again its continued and this time it saved lots of power and is a good concept. Most countries all over the world adopt the Day Light Saving time to save the energy every year.
Day Light Saving must be continued and it will probably be continued every year to use more of natural energy. This not only ease the local power consumption but also in turn reduces the carbon which is being thrown to the environment. So Day Light Saving is indeed environment friendly stuff helping us to keep the earth green.
