Well I feel that the article confirmed that coal would be with us for the long haul - but anyway.Coal fired energy in Australia will always be cheaper than renewables if all subsidies, penalties and taxes are controlled for - as discussed here.You have defended your position grandly, and also shot yourself in the foot, in one go. Impressive!
I totally accept that running an existing 'coalie' may be cheaper than installing large scale renewables today, but I also totally accept that installing wind + storage even without subsidies is cheaper than installing new coalies. Refer to the link I posted on page 22.
In light of that, please tell me what would be more beneficial to replace the existing coalies when they expire?
I respect the fact that you're prepared to argue without personal insults and I'll throw an alternative greenhouse gas management scenario. If Australia wanted to dramatically reduce global carbon dioxide emissions then we could simply ban all coal exports; that's a really, really radical thing to contemplate but the fact is that if we did that we'd substantially help with global greenhouse gas emissions. Same with gas - don't allow it to go off-shore and insist that it all gets burnt here or not at all. It would help massively with the carbon fairy, assuming that's the primary goal.
I'm well aware that it would fly totally in the face of the neo-liberal "free-market" convention bullsh*t but it's a realistic solution to what the anti-carbon dioxide people want to achieve AND it would have the added benefit of making our own consumers and industries super-competitive against imports because of our on-shore advantage with cheap energy. Hell, you might even see companies come back to Australia with manufacturing again, imagine how that would put money back into the pockets of the average semi-skilled or unskilled worker.
It won't happen though because Hawke/Keating neo-liberalism collides with the "Save the Planet" mob on actually restricting international trade, they will not even consider anything that radical - our coal and gas must continue to be burnt at record rates, it's just that we're not allowed to burn (coal especially) domestically any longer... for some reason. Even though it makes not one iota of difference to planetary carbon dioxide.
