Such an interesting topic and one that's just been waiting to burst out in Australia.
The advent of technologies is not going to go backwards and I see nuclear power getting bigger and more common around the world in the next 20 years or so.
It's now becoming apparent that whilst all the major corporations were busy coming up with all those electrical items we desperately need to fill our lives with, no-one really stopped to think how we would continue to power all these in the future.
If all computers were shut down for a year (which would of course never happen - just a hypothetical), I wonder what affect that would have on electrical demand from the power stations ? It's only been the last 20 odd years that computers have grown in enormous numbers around the world.
Everything these days is electric, your fridge with built-in internet access, your home theatre system, your 3 TV's, not to mention all the PC's around the world. With demand growing, fossil fuel power cannot keep up without completely destroying our atmosphere....which in turn will eventually destroy us.
The downside is the management and storage of spent radioactive waste, but if we keep on going the way we are now what will kill us first, leaking nuclear waste in the indefinite future or the gaping hole in the ozone layer (that is only getting bigger and worse) ?
What is more interesting is that the US are looking at Australia as a potential "perfect site" to house their radioactive waste. I'm not sure if anyone saw the "Sunday" program last weekend, however it appears that there is some speculation that it would be in Australia's interest to look at producing radioactive waste sites to house other countries waste....which could make Australia Billions of dollars per year. With this money, we could produce our own reactors and possibly even strengthen our economy (if done correctly - which is a big ask of any politician).
If this were to happen and Australia did begin housing waste from other countries, it could be seen as foolish for us not to have our own reactors and store our own waste along with the rest of it.
Is nuclear safe ? Do we all really know the "facts" behind it all ? If not, it's all just speculation until it comes to fruition. If the government want it to happen, it will happen...regardless of what the public have to say (IMHO).
The downside is a tremendously scary thought, should a leak ever occur....however choosing between that and ruining the planet we live in, it somehow seems a more sensible choice....
As for other "greener" choices, I agree that economics come into it and if it's not cost competitive to nuclear it is likely to be overlooked.
Interesting topic though....
