Err... no need to be that extreme! 
By all means live in a sustainable and energy efficient manner. Just be aware that we're not 'going to hell in a handcart' in our lifetime, or our grandchildren's. For instance we have at least 5000 yrs of oil left, but its estimated that solar energy will be practical for most if not all energy needs in approx 50 yrs; the sun is estimated to provide enough energy for all our needs more than 700 times over.
Its all in the book, the figures are all from the UN and WHO, and widely accepted as correct.

One thing that makes me laugh about this whole earth hour thing...
Certain types (infact most) electric light bulbs / tubes are more efficient when you leave them turned on all of the time.
In fact, some types use more energy at the point of switching them on than they do for an entire hour of running.
So that kinda cancels out the idea of switching them off for an hour to save energy, doesn't it?
OK, I'm being pedantic. But this is the environmental version of a crash diet. We need to change our lifestyles to get into the habit of using less energy all of the time so stunts like turning everything off for one hour will not promote sensible energy use.
