Its plentiful and its greener than both wind and solar. Furthermore i am assuming the point is reduction of co2, if thats the case then does it really matter in this context?

I think it matters only because there is a strong contingent of alternative energy supporters that do not see nuclear as part of the mix when talking about ‘renewables’ and for those folks the math is really hard. Conversely the math is easy with a strong nuclear mix.

Oh I get that but it also illuminates the shallowness of their position given that the reason they are against wind and solar and hate fossil is because of CO2.

Nuclear is literally the best combination of the best features from each of the other forms of energy.

Who cares if it's renewable when it's inexhaustible.

640K should be enough for anybody(tm).

is fission material inexhaustible?

It is inexhaustible in the sense that fuel is not the limiting factor on how many nuclear power plants we can build.

In this context yes. The sun also run out of juice sooner or later.
