We can see how risky it is to have a nuclear power plant providing our daily energy needs, but unfortunately it is convenient at the moment... at least until something happens and our 'convenient' source of electricity begins to spill deadly radioactive particles that begin to kill us slowly and usually in a very nasty way. Japan's current crisis is the best example of this scenario, so we as society have to think of alternate ways to generate our daily electricity needs.
