31st March 2012 was the first Earth Hour event in 2012.
Starting from 08.30 PM until 09.30 PM local time, most people turn off the lamp to give the earth some rest time.
Here are some photos during the first Earth Hour in 2012 🙂
“A symbolic gesture to raise awareness about energy consumption, Earth Hour has grown since its beginning in 2007 in Sydney to now include observances in 147 countries and over 5000 cities. For one hour, lights are switched off at 8:30 local time on the last Saturday in March. Increasing public environmental awareness in China, which has overtaken the United States as the world’s biggest polluter, has led 124 cities there to mark Earth Hour. “
