The green future is full of promise - and according to the timetable from Berlin you can almost reach it with your hands.

By 2045, Germany should be climate neutral and meet its electricity needs entirely from wind, sun and, where necessary, storage media such as hydrogen.

A nice view and possible in theory.

In practice, however, the road to get there is rocky.

This is also due to the fact that, in terms of energy policy, people like to take the second step before the first.

Take the nuclear phase-out as an example: At the end of next year, the remaining reactors will finally go offline, and the operators categorically rule out longer operating times.

This means that many gigawatts of secured - and climate-friendly - generation capacity are dwindling without the electricity highways promised parallel to the nuclear phase-out being ready.

At the same time, the coal phase-out is progressing.

For better or worse, new gas-fired power plants will have to be found in order to secure supplies when there is no wind.

They are not as climate-friendly as nuclear power plants, they cost and make you dependent on Russia.

But the nuclear phase-out has its price.
