Well now here's some good news!
The first commercial version of a new kind of power plant, called a "Solar Tower", is set to be completed in Australia in 2006. This thing is cheaper than a coal plant with the same power output, and produces no pollution whatsoever!
Of course there's no way our energy sector will allow this hippy crap to set foot on our soil, so it really is going to be up to us to push like hell for this. Make a mental note.
