Celebrated Earth Hour 2011 at Ikea Tampines in Singapore. Of course, do not expect Ikea to switch of f all lights due to security and safety reasons. If I am correct, only the cafe lights are turned off (not sure about the outside building lights).
Kudos to Ikea for taking part in the lights off during the Earth Hour (26th March 2011 8:30 pm to 9:30 pm). I realized many Singaporeans are not aware about it.
Prior to the hour, Ikea staffs were busy placing solar energy lamps around the cafeteria. Some are actually enjoying the atmosphere. Here is a short clip before and during Earth Hour 2011.
