If there is no more gas, maybe nuclear power can help?
It is difficult to answer the question of how Germany will find its way out of its dependence on Russian gas, which has helped Putin to finance his war against Ukraine and to provide for economic sanctions from the West.
In the short term, the country's supply is secured.
In the medium term, other countries will have to refill the empty gas storage facilities.
In the long term, we need our own renewable energy plants so that the times come to an end when dictators can abuse fossil fuels as a means of exerting military pressure.
The call to quickly revive our intact nuclear power plants or at least to keep them running is understandable.
Even former opponents of the technology consider this to be justified in this situation.
But it needs realism: our nuclear power plants cannot replace the energy contained in imported Russian gas.
Germany consumed almost 1,000 terawatt hours (TWh) of natural gas last year, and a good half came from Russia.
At the same time, the last nuclear power plants generated almost 70 TWh of electricity.
All renewables came to 237 TWh, which also shows the dimension of the dependency.
And not all energy is created equal.
We cannot heat homes with nuclear power if, in half of all households, the only way to the radiator is through a gas boiler.
Some people cook with gas, many factories use it.
All of this can perhaps be rebuilt in the long term, but not in one summer.
And yet: nuclear power can compensate for the fact that part of the natural gas is converted into electricity.
