Earth Hour 2008 - Lights Out

In a huge expansion of the Earth Hour event hosted by Sydney last year, the WWF has promoted the event around the world.
As of tonight there are over 235,000 Individuals and 15,000 business registered to be involved.
There has been some comment that this is a token effort. However, when you take into account the number of people involved and if each person saves just .5 of a Kilo Watt hour (Kwh) that is over 100 Megawatt/hours and assuming that a business will save this amount again, we are talking about the output of a medium sized power station for 1 hr.
More importantly, if this becomes a habit, then the savings become signifigant.

From an Astronomy point of view, it is a huge opportunity to make people aware of just how much difference it makes, turning off unnecessary outdoor lighting.

So make sure you make the effort, register at http://www.earthhour.org/sign-up

GAA will be holding an observing night here in Gove on Sat at 8pm on Hindle Oval.

This is how it happened last year:
