>Building a modern zero carbon economy based on renewable energies is not only possible but also close to cost competitive to the nuclear-intensive alternative [1]: Oh yeah? Point me at an example. This is not a question of ROI. Wind/Solar could be free and still could not power a modern economy. There are no economies of any significant size (say, larger than a mid-size city) that are powered by wind/solar. There are no economies that have plans in the near-to-mid term to be powered by wind/solar. Why was Germany, up until recently, investing billions to ship Russian gas for decades if wind/solar is just around the corner? So what are we talking about here?
