At 8:30 pm I switched off the main switch of my home.When my sister called at the right time I informed her also and she ordered her son to switch off the lights.
My coworker in college send group messages and I also got it.At the same time I called him and told the method I followed.
I ringed to my wife house where they didn't observed it.They also informed the news.
My neighbour's son-in-law came to park his car in my yard.I told him that I am observing Earth Hour.THat is why here only it is dark while at neighbouring houses there is light.
I had switched off all lights and sitting in open during the Earth hour. But during this period, my CPU was brought after changing window. so, i had to switch on the light. I have also written something on internet about global warming.
