Very informative thank you. From this rebuttal I see that the movie probably packages true information, some of it outdated, in a provocative way.
The only fully scientific rebuttal is to run the experiment: run the whole economy without fossil fuels or nuclear, and see how much it looks like the middle-ages, how much it looks like utopia. My guess is 80/20 on the middle-ages side, but who know.
The rebuttal is in the beginning stating that Germany's renewable electricity production is important and not it's total energy consumption, at the end they claim that we need to shift all of our energy consumption to renewable electricity. This is a fundamental contradiction.
