Nuclear requires least amount of materials so you can stockpile uranium for a decade and be fine
Solar panels on each square cm of roofs together with agrovoltaics and solar on every farm and a few more of those 2TWh hydro storage plants we have, and we are energy independent and can service a large part of our infrastructure ourselves.
Solar requires more materials per kwh even compared to nuclear. But even if it didn't - since hydro potential isn't sufficient - gas is required for firming. This was also mentioned by axpo
Solar doesn’t require more materials per kWh. LCOE of solar is order of magnitude lower than Nuclear.
And we do have more mountains that we can build out.
