Few reasons why I don't like observing earth hour in India are,the first and foremost being my scepticism towards the global warming or climate change phenomena. The second reason would be that we already have our electricity guzzlers turned off,though involuntarily in the name of power cuts. Depending on the region were people dwell, electricity is not available for about an hour or two in a metropolis and anywhere between ten to eighteen hours in the rural areas. The situation worsens in the summer months as the demand for electricity spirals up way above the supply and states have no other option other than resorting to scheduled or unscheduled power cuts. In such a scenario it makes no sense for us to turn off the lights.
Another reason why I wouldn't advocate observing earth hour is we don't achieve anything by just switching off our refrigerators or lights or fans for a few hours.The effect of such an initiative is going to be minuscule and I see no point in participating in it.
So the next time I hear people saying they are going to observe earth hour I simply wouldn't give a damn and turn on all the acs and fans , in assurance that I can enjoy them as the demand for electricity would have come down in my neighbourhood.
