Nuclear power, hands down.
And here is why: It is safer; meltdowns have only occured due to human error [ie: employees being over worked or jobs done unsatisfactoraily]. Plus the waste produced by the plants is not actually going to damage anyone provided it is stored properly. Meanwhile coal plants emit tonnes of wasted carbon that pollutes the atmosphere and destroys our health and the environment.
It is cleaner; as above, no carbon pollution means its cleaner and the sky is blue! It is! It really is, as anyone down here or not in a major city will tell ya ;)
And finally [in the case of Australia, which concerns me more than the rest of the world] it is an economic boom! We have the largest uranium reserves in the world! Wootness! Thus we can develop an entire industry around producing feul rods for other countries! Now aint that just dandy!
