Earth Hour
Well, it's pretty simple. First of all, it's one hour out of 8.760 in a year. That's not going to make a difference. It's largely a symbolic thing. Maybe it raises awareness, but I don't think it really matters that much.
Secondly, how are people going to live without electricity? Well, they'll burn stuff. They'll put a fire in, maybe have a bonfire outside, and light a bunch of candles. That, to me, sounds much worse than using hydroelectricity, which many people have, to power your low power/energy efficient light bulbs. I turn off lights every time I leave a room, so there's no benefit from turning off all the other lights in my house either.
I think this event is being overhyped beyond belief, and may actually be doing more harm than good. Regardless, it is a unifying event, that involves worldwide collaboration to get everything done. Entire cities power down. But I don't think it's the genius idea that it's being played up as.]]>
