maybe not in this generation but nuclear generated power will be a sure thing and it will be safe and enviro friendly (hard to believe but true) and part of the push will be because of the following from your post MT but that's no surprise given most of them believe climate change is a myth. the amount of greenhouse gas from np is extremely small compared to fossil fuels, we have a coal fired kiln at work burning 380+ tpd, generating copious amounts of nasties into the air i dont think i will see it go np in my working life time but 40 -50 yrs from now for sure
its true that cost is a factor but advances to technology will lessen the cost to that of coal and gas
other renewable sources like tide, solar, wind, geothermal, will contribute but alone they will not be sufficient to meet the demands of our electrical needs, its been estimated that the average household in 2020 will use 30% more power than we do know as we use 30% more than we did in 1970 look at how many more electic gadgets we have compared to 30 years ago
this is a very emotive topic which will polarise the whole country, be prepared for some very drastic actions from "normal" australia ,but the future generations will carry this through to its fruition
