Granite extraction and especially treatment, given ore grade, would imply gigantic greenhouse gases emissions, isn't it? This will be more and more of a challenge even in uranium mines: https://papers.ssrn.com/sol3&#x2F

France is (by far) the world leader when it comes to the fraction of nuclear-produced electricity and always produces around 9% of its electricity thanks to fossil fuel, because building enough reactors to satisfy peaks and to load-follow w

Indeed. The money allocated by the gov isn't falling from the sky (or if it is, it is printed money, leading to inflation): the fundamental question here is therefore "is the government more efficiently allocating this money than

Indeed, however no one (or nearly) now advocates those energy sources (as they emit way too much greenhouse-gases). This is to compare to emissions of renewables sources.
