No more cars, no flights, rationed and allocated living space, economic output and consumption halved – the life that the taz editor Ulrike Herrmann describes in her current bestseller “The End of Capitalism” and that we all supposedly inevitably face is barren.

Because, according to Herrmann, wind and sun will never provide us with enough energy to maintain our current level of prosperity. I appreciate their honesty, many climate activists want to make us believe that with a few increases in efficiency, a speed limit and the ban on private jets, an industrial nation like Germany can make ends meet with renewable energies alone.
