Earth Hour 2015 is this Saturday, not sure what time the switch off is.
I’m expecting to see Taipei go black .
The Earth Hour page says 8:30 – 9:30 local time.
To be honest, this is the first time I’ve heard about Earth Hour. It’s a cool idea; however, the Spiderman tie-in, as shown in the 2014 video, seemed to cheapen it for me. Whatever works, though.
