Coal power

But I doubt they looked at any numbers that didn't agree with their predetermined narrative

You doubt,but do you know that they didn't?
And what's the point of even bringing it up if you failed the very same thing you accuse them of?
They'll just turn around and blame you for a predetermined narrative.Yes?

The other figures I quoted are right from the charts. only 22.4% of Germany's electricity is solar and wind. And only 4.1% of primary energy is solar and wind.

On at least one occasion,wind and solar provided 75% of Germany's electrical power load.If they continue to build out renewables,given the same conditions,wind and power could provide 100%.

Ask the people in the Carolinas how they feel about coal - now that the fly ash has spilled in so many places.

That ... stuff ... is full of all the worst poisons and toxins, and it is a major cost of coal that is not included in the price we pay for electricity.

And mercury contamination - don't forget mercury that is now in everything in the sea.

I happened to look up what's cheapest overall to install, fuel, maintain while getting my associates in applied science for power plant operations.

If they had bothered to look anything up beyond the name plate watts install cost then they would know solar isn't the cheapest, it's not even a cheaper way to generate power.
It's one of the most expensive ways to generate power aside from oil and thermoelectric.

What other explanation is there?
I see 2 possibilities
1 They are brainwashed, ignorant, misinformed, useful idiots
2 They are knowingly repeating a lie in the hopes that if they repeat it enough times it will become true.
3 I'm open to additional possibles.

Germany is mandating solar be installed. Their electrical costs to consumers have gone up to 150% of original compared to 10 years ago.
By the time they hit their goals they will likely more than double the price of electricity.

I'm sure anyone crying about the coal fly ash spill will change their tune after 48 hours with no power in the summer.

Germany produced 6% less solar in 2016 than in 2015 despite having added more solar capacity in that timeframe. It just wasn't as sunny in 2016.

Fluctuations in renewable energy that vary by 6% or more creates technical problems that are likely to be expensive to solve. The system has to be built with much over-capacity so that when conditions aren't favorable, people still have power, but then that over-capacity is a huge added expense.

Perhaps Aluminum factories could operate more like ER doctors in that they are scrambled in to work when there is an over-production of electricity and energy is "free", and sent home when the sun isn't shining.

That sounds like a 1960 or 1970s scifi book.

Perhaps those who lost their homes and a loved one are thinking twice about the wisdom of Duke Energy's coal-fired electricity,CSX Railroad who brings in the coal,and the entire coal infrastructure,if these had anything even remotely to do with the intensity of the weather events of Florence.

How long until they can drink clean water, I wonder?

Oh, and after a storm, guess which power generation sources are first to generate electricity? Renewables ...

Offshore wind is where the major investment is going.The average wind is of greater velocity and less sporadic than onshore.
The foreign coal operator in Germany is trying to sell off their business and turn around and invest in offshore wind.
Even Nuclear,gas,and coal have downtime scheduled each year for preventive maintenance.None of them have a 100% duty cycle.
