Every energy source does require some sort of energy to make it possible to harvest it. And nuclear is no exception. We do not have any sustainable way to filter out enough carbon dioxide with any of the hypothetical excess energy.
So saying there is a any energy source without any carbon dioxide emission is wrong.

Indeed, and neither are solar, wind, hydro or any other - they all have environmental impact for producing the panels, turbines, dams, etc. So there are actually no exceptions at all, anywhere, which makes the classification completely useless. Could we get back to the topic now?
