"France has the cheapest electricity, the lowest carbon emissions, the most diversified gas supplies, why is European energy policy about breaking EDF and GDF?" In the long run, we're all dead. John Maynard Keynes
And there is the ugly little side issue of France's colonial exploitation of Niger as a nuclear fuel source, and the question of nuclear waste disposal. Wind is fine, but France's low carbon emissions and cheap electricity come with a social cost that is not being factored in...
As to Niger, I'm all in favor of "full accounting" for all energy sources, as this can only make renewable energy look better, overall. I'd note that given the much lower portion of fuel costs in nuclear, the social impact of the extraction of uranium has to be much lower than that of fossil fuels; I'd also note that the majority of the uranium used in France comes from Canada, Australia and the former Soviet Union... In the long run, we're all dead. John Maynard Keynes
