Volker Quaschning macht in seinem Beitrag deutlich, was es bedeutet, den Klimaschutz ernst zu nehmen. Dann bedarf es etwa eine Verdopplung des Windenergie- und fast eine Verzehnfachung des Solarenergiezubaus, den schnellstmöglichen Abschied von der Öl- und Gasheizung sowie von Benzin- und Dieselautos und den schnellen Ausbau von Energiespeichern", so Quaschning. Wer das alles nicht wolle, müsse entweder einen Plan B für den Klimaschutz präsentieren oder sollte sich Donald Trump beim Leugnen des Klimawandels anschließen.

Our hunger for energy -- The climate before the collapse? -- From wasting energy to saving energy and reducing carbon dioxide -- "Energiewende" (energy transition)--the way to a better future? -- Photovoltaics--energy from sand -- Solar thermal systems--year-round heating from the sun -- Solar power plants--even more power from the sun -- Wind power systems--electricity from thin air -- Hydropower plants--wet electricity -- Geothermal energy--power from the deep -- Heat pumps--from cold to hot -- Biomass--energy from nature -- Renewable gas and fuel cells -- Sunny prospect--examples of sustainable energy supply.

Wie kommen wir aus der Klimakrise? Reicht die Energie von Sonne und Wind? Sind Elektroautos wirklich umweltfreundlich? Ist Wasserstoff der Heilsbringer? Was können wir selber tun, auch wenn es uns schwerfällt, unsere Lebensgewohnheiten zu ändern? Solche Fragen stellt man am besten Volker Quaschning, einem der weltweit führenden Experten für regenerative Energien. Mit seiner Frau Cornelia Quaschning erklärt er an konkreten Beispielen, wie der Umstieg auf eine nachhaltige Wirtschaft gelingen kann. Aber eines machen die beiden auch klar: Die Zeit wird knapp. Eine Energiewende reicht nicht, es braucht eine Energierevolution.

In March 2019, German-speaking scientists and scholars calling themselves Scientists for Future, published a statement in support of the youth protesters in Germany, Austria, and Switzerland (Fridays for Future, Klimastreik/Climate Strike), verifying the scientific evidence that the youth protestors refer to. In this article, they provide the full text of the statement, including the list of supporting facts (in both English and German) as well as an analysis of the results and impacts of the statement. Furthermore, they reflect on the challenges for scientists and scholars who feel a dual responsibility: on the one hand, to remain independent and politically neutral, and, on the other hand, to inform and warn societies of the dangers that lie ahead.
