Recently came across this interesting idea: Earth Hour.
Basically, it's another one of those calls for a simple, massive grassroots action whose effects would be more symbolic than effectual, though the whole idea is at least thoughtful an interesting. For the sake of the environment, the idea is that people all around the world will be turning off their lights and other power for one hour.
The time for this synchronised action is... 8:30pm - 9:30pm.
Nuts, I'm typing this within that time window.
Well, I suppose that those of us in more northern locations where the sun sets early, can get a special dispensation to take our hour-of-no-power at some other time. ANNNNNND, the web site gives the above times, but does not say in which time zone, so I do it, it will probably be around 8:30pm somewhere.
I guess the bottom line is that it would be good for all of us to just try a powerless hour some time in or around this weekend, and pick it at a time when we might normally use power. And more generally support efforts to minimize wasteful practices.
