If they pivoted to a renewable heavy grid, could it not be the same governmental policies which depreciated nuclear also depreciated coal/oil? From what I can see Germany started giving governmental support to renewables in 2000 https://en.wikipedia.org/wiki/German_Renewable_Energy_Sources_Act https://en.wikipedia.org/wiki/German_Renewable_Energy_Source... Also renewables simply just became far more economically viable relative to nuclear/coal/oil on a technological level in that time. So to me, the more natural conclusion is "why, renewables became more economically feasible, so they pushed out all these other forms of energy" not "Take out nuclear energy - and coal/oil fall like dominos". I really don't understand the basis for the causation being drawn in the article.
