Nuclear waste a hazard forever
While I do not doubt the information he provided regarding current global energy consumption and demand, I feel that several important points were not mentioned.
While the generation of energy by nuclear means does not directly produce any of the greenhouse gases that we hear so much of today, the process does leave us with another problem in the form of hazardous nuclear waste. As yet there are no technological means safely to dispose of this waste. The current ‘solution’ to this problem is simply to bury it.
