I think a few more things need tp be said about this.

And to get a better picture, lets start at the beginning. The development of nuclear energy in spain started in the late 40s und fascist dictator Franco.

To advance Spain economocally and technologically aswell as further its prestige, Francos Regime looked into how to develop nuclear industry. Image

Können nicht alle deutschen "Intellektuelle" die andeuernd ihre Jammerartikel darüber verfassen, wie schlimm doch die Deutschen wären kollektiv auswandern.

Lasst uns einfach alle auswandern, ich gehe nach Estland und ihr geht nach ... äh, hauptsache nicht nach Estland. Der Unterschied wird sein, dass ich mit den Esten ne gute Zeit haben werde, während ihr euer neues Land am Ende genauso hassen werdet wie Deutschland.

Warning: Tangent.

German nuclear while operating extremely cost efficiently was also operated extreamly safety obsessed.

One of its obsession was protection against aircrafts crashing into it.

Well before 2001. Image This started in the 1970s when a british fighter jet crashed a few kilometers away from the WĂĽrgassen npp a GenI BWR close to which a grew up. Image

So do you remember half a year ago, when I wrote about the condensation enthalpy.

Lets continue that and talk about where it becomes important once again.

Hydrogen: Image If you don't please read this, but basically: The transition from liquid water to steam itself, not any temp change, requieres massive caloric input.

There are three owners if remaining German npps:
-PreuĂźenelektra owns 3, one operational
-RWE owns 2, one operational
-EnBW owns one operational EnBW is staterun, owend by a federal state run by a green government.

Gues what they think about Atomaisstieg.

Renewabros:
"Germany gets 50 % of its electricty from renewables, isn't that great."

Once again something that needs context checking. A large part of those renewables is biomass.

A third only comes from wind and solar.

Lets get to another ramification of the phenomena of condensation enthalphy:

Lower and upper heating values.

The ones that know, know this gonna be great.

Oh golly strap yourself in, we are going for a ride, this gonna be fun. Ok I lied it wont be.

This is gonna be a boring ass lecture about the difference between popular understanding of energy density and the understanding that people actually working with combustion technology have.

Since you now all know about condensation enthalpy we can talk about where it becomes important.

Lets start with something easy.

Cooling towers. Nuclear power plants, like coal power plants, like gas power plants and the engine in your car or truck are heat engines.

Difference is they run on stardust and not prehistoric bioenergy.

And like all heat engines they dont just make mechanical power which is then turned ...

Putin model of a ruler is Tsar Alexander III, which realigbed Russian foreign policy from an alliance with Germany and Austria Hungary to ak Alliance with France. He did that out of his visceral hatred of all things German and Bismarck in particular.

Alex III put Russia on a collision course with Germany before Wilhelm the II could.

Reading your comments on energy over the last two years made me realise, how many of you either dont know about condensation enthalphy or are not aware of the importance of condensation enthalpy.

So lets talk condensation enthalphy. This is a diagramm of the temperature (in °C) of a kg of water as function of the heat put into it.

I am sorry it is in German, but I think you will still get the relevant data out of it.

You may notice those wierd areas where heat is put into the water without the temp rising. Image

Till the winter day when they will crush the grid.

Home heating has several times the peak demand of its mean demand.

But that peak demand has to be met or people will freeze. So installed capacity of assured generation to meet heating demand has to be several times mean demand.

Leading to a huge amount of power plants being underutilised wasting industrial capacity, labour and resources.

@gwen_m01 @AnnonDocss @BMoens Germany has:
-closed down 28 GW of nuclear power plants
-abandoned the plans it had to build new nucöear
-shut down its domestic bitouminous coal industry
-slashed what little gas exploration it has
-refused to utilise the vast shale gas resources beneath North Germany @gwen_m01 @AnnonDocss @BMoens -bullied its neighbours into closing their exisitng nuclear fleet
-tried to prevent their neighbourghs from building nuclear power plants
-made itself utterly dependant on russian primary energy and oil refining as it has nit build an oil refinery in decades and relies on ...

Germany employs 20 000 people per 1 GWp of solar it installs per year.

It would need a minimum of 2 500 TWh of electricity to replace all its fossil fuels, at the 11 % cap of German solar that would require 2 600 GWp or 52 000 000 manyears just to install them. If your plan to do that in 6 years you would need 9 million people working in solar just to install them.

Keep in mind Germany does no longer do the production of solar and never did the mining and we have never done proper large scale disposal and recycling.

Ich bin ein Jahr lang mit dem Zug von Heidelberg in mein Zuhause nach Reinhardshagen gefahren.

Eine 6 stĂĽndige Odysse bestehend aus StraĂźenbahn, Regionalzug, ICE, Regionalzug, Bus.

Die Verbindungen Kassel-Mannheim, Mannheim-Heidelberg und die Heidelberger StraĂźenbahn ... ... stehts versifft und ĂĽberfĂĽllt.

Das ganze hat mich dann hin und zurück mit Bahncard50 100 € gekostet.

110€ wenn ich im ICE nicht stehen wollte.
