Nuclear is not offering the best price per Mwh now (https://en.wikipedia.org/wiki/Cost_of_electricity_by_source), but it will certainly in the next decades.

Solar and wind power sources requires an absurd amount of metal (sometimes rare metals) to build the generators (solar panels, wind turbines, etc). This metal is extracted today with an enourmous consumption of fossil fuels, and it will be difficult to have a greener alternative for this extraction (anything running on batteries will require even MORE metal).

The prices per Mwh of renewable energy sources are heavily linked to the prices of fossil fuels, which are quite "low" compared to what will probably happen in the next decades. Moreover, most metals are getting harder and harder to extract (it's likely that we met the peak of copper extraction already), which means that we'll have to dig deeper and deeper to get metal.

I'm not saying we should not invest in renewables, but it will be probably be 10x to 50x more expensive to maintain a renewable parc of solar panels or wind turbines without relying on fossil fuels at all, which will cause the prices per mwh to explode.

Countries that try to go 100% renewable without a healthy dose of nuclear energy will probably end up either burning fossil fuels or buying raw materials from countries that does, at a very heavy price.
