Quaschning:Energy revolution now: Mo

How do we get out of the climate crisis? Is the energy from the sun and wind sufficient? Are electric cars really environmentally friendly? Is hydrogen the savior? What can we do ourselves, even if it is difficult for us to change our habits? These are the questions best posed to Volker Quaschning, one of the world's leading experts on renewable energies. Together with his wife Cornelia Quaschning, he illustrates with concrete examples how the transition to a sustainable economy can succeed. But they also make one thing clear: time is running out. An energy transition is not enough; we need an energy revolution.
