You are both right and wrong at the same time.

Long time ago when Siemens in Germany was still building nuclear power plants, I was working in the nuclear power plant engineering department. After the year 2022 when the Russia invaded Ukraine, the gas shortages and the following costs hikes renewed my interest energy sector. Why didn't German reverse it's anti-nuclear stance, even with war in Europe?

Was is the general lack of knowledge of physical, technological and economical aspects of energy, both in German population and decision makers?

The political aspect became clearer after reading "Akte Atomausstieg" by Daniel Gräber.

Little bit of money from oil and gas industry always helps.

I think solar and wind are interesting technologies, (solar almost magical - turning photons of light inside thin layer of doped silicon into electrons) but by itself insufficient to power modern world. They are intermittent, weather dependent and low density. Yes the sun and wind come free from Sun, the machines that convert the energy, store it and distribute it are not. Minerals have to be mined, machines build, transported, installed and then disposed off.

There are still big hydrocarbon reserves, gas/oil for atleast 100 years, coal 200 years, at current consumption rates. I fear that, if we don't use the only carbon free high density energy source and cling our hopes to the mirage of renewables, we will transform our atmosphere to hell.

When even the oil and gas giants advertise for renewables, you know that renewables will never replace fossil fuels.

I dislike ‘energy religion’. Nuclear is necessary for Europe. We simply can’t heat our homes and power our industry with renewables in winter. At the same time wind and pv can be built up faster and is simply cheap. Hydro where topography and local bio conditions allow it. We need all those technologies, so we can move away from fossil (climate, resilience and depletion).

The real question is "why are nukemen so desperately against renewables (and therefore by default in favor of fossil fuels)?" The all-nuclear future had its moment in the sun in the 70s and has been comprehensively lapped. Only France came close.

> the machines that convert the energy, store it and distribute it are not. Minerals have to be mined, machines build, transported, installed and then disposed off

This is of course also a valid argument against nuclear power.
