..........this concept of earth hour is against physics...
see how
Light and electrical appliance are supposed to be switched off to save energy......
http://en.wikipedia.org/wiki/Earth_Hour
by definition.....shut all devices runing on electricity....
1) Lap top is 'on' using a battery [1] that was charged using the electricity before and when u switch it back u will use the same amt to charge it back.... I will charge my laptop at 9:30 again wohoooo.....
saving = 0
2) Cell phone on [1] ...battery charged...blah blah.... i will charge cell phone at 9:3-pm ....
saving = 0
Now the biggest QUESTION for all................
... anybody who answers this convincingly.......i will take my words back.....
Energy can neither be created nor be destroyed...............................
Einstein

save energy = convert and store
use it later... !!!! :(
So i think the concept should be "save energy for future" and not save energy...
