Earth Hour is celebrated worldwide and this year it was done last Saturday March 23, 2013. At exactly 8:30 pm, I closed all our lights (but TV was on for a while lol) and told my mom that we'll be joining once again. I just let her watch TV and later on she closed it too and just went to her bed.
Total darkness... so I just opened our emergency light on so we still have a light but w/o using the electricity. This is our way of joining and helping save Mother Earth even just for an hour of closing the lights. I just hope that next year, I will be joining once again.
