I think it is increasingly obvious that nuclear power has to be seriously considered. At least we have the advantage of being able to put the power plant and its waste in some desolate wasteland, miles from civilisation, like the back of Bourke or Ipswich.
It has? Not to my knowledge.
But that would be typical - it has as many if not more problems and potential problems as Coal. I don't see the current nuclear technology as the long term solution. I think Australia would be better off sticking with coal as we actively seek a better long term solution.
Nuclear power should at least be a medium term solution however. It is a proven and mature technology (and remember Fukishima was a very early generation, 60s design, Nuclear plant, the designs of modern plants are not susceptible the the issues that happened there) and it's a zero emissions technology.
Obviously, the holy grail is Nuclear Fission, IF that ever becomes practical, the world's energy needs will be met without question.
Also, there are developments in Nuclear technlogy which involve different nuclear fuels, those with very short half lives, which would completely address long term radiation concerns. These of course are not commercial as yet, but they probably should be pursued...
The Greens have also now admittted that they refused to allow Carbon Capture Technology to be included in the $10 billion clean energy fund... in spite of the fact that it is closest to full commercial application and would greatly reduce and possibly elminate CO2 emissions from coal burning power stations. They are so focussed on destroying the coal industry at all costs, that they are not prepared to accept a technology that WOULD provide significant reductions in emissions and in the shorter term. This just shows them up for the hypocrites they are.
Lastly, he's a good article...
