After a comparison between the energy of fire and human performance, the history of sustainability is briefly discussed. This is followed by observations on the human influence on the carbon cycle. The resulting consequences for climate change are outlined. A look at the world's energy reserves shows that we would destroy the conditions created in carbon, which have enabled higher life on earth, by burning them completely.
The most important technical potentials of the energy transition are shown and briefly discussed. The positive contribution of electromobility is discussed. Its aberrations, such as biofuels, are also discussed, as they are currently being called for again.
According to what is now almost certain, the pace of the energy transition is too slow to achieve the Paris Agreement target of limiting the temperature increase to 1.5°C, which is binding for all signatory states under international law. Parallel to climate protection by restructuring our energy system, measures must therefore be taken to remove CO2 from the atmosphere. The proposals and technical options available for this will be discussed. There will not be one method of choice, but only a bundle of different measures appears promising. One of these options is the reforestation with partial final storage of the wood proposed by the author in 1996 and 2008, which is discussed at the end.

Based on a brief presentation of the scientific consensus on the pressure to act on climate protection, lesser-known options will be presented. For example, methane pyrolysis could be superior to other routes to hydrogen, while biofuels are more likely to occupy niches. Of the numerous proposals for cleaning up the atmosphere by geoengineering the climate, the geostorage of wood is likely to be particularly promising.
