I can guarantee you that the bleating that would occur from most Australians, if they had to make do in a country that no longer relied on its mineral resources, would far outweigh the current noise from those who think a complete switchover to renewables can happen in the next 30-50 years.That's the real issue. Australia is rich due to its immense resources. It's fine to say get rid of fossil fuels and replace with renewable energy but we have to, as a country, be prepared to take a massive hit on our quality of life, at least until we find something to replace the lost revenue. I don't think people in Australia are prepared to accept that as a whole. Politically it's not a simple solution.
It's also very easy for European nations and the US to point at us for using so much coal and gas to generate power when they've had nuclear power to prop up their their baseload for decades.
We've been hamstrung by gutless politicians and a "green" lobby that gets far too much attention paid to it and isn't really green.
