Nuclear has shown no particular inclination to come down in price whereas renewables have.

It's just not cost effective without both massive implicit and explicit government subsidies.

Renewables are cost effective now and will only become more so.

They're cost effective when the sun is shining or wind is blowing but are strongly tied to increased high carbon fracked natural gas otherwise. When batteries are used the Energy Return on Investment drops below what's necessary to sustain industrialized civilization (around 5:1).

Even without including cost overruns and decomissioning, wind energy costs the same per kilowatt of capacity[0,1].

And the actually produced energy as share of capacity (= the capacity factor) is way better than most think. For the nuclear plants in France it currently is just over 70%, while it is about 50% globally for offshore wind parks [2,3]

Edit: Changed phrasing because it apparently sounded like the 50% capacity factor also referred to France.
