9. Ah, the good old "Eloon's slaves" solution. I calculated how much Eloon's cobalt slaves would need to dig to cover...

...a Dukelflaute event in 2022 in that coal dependent antinuke hellhole Germany.

It's here: The Number of Tesla Powerwalls Required That Would Address the Current German Dunkleflaute Event.

The Last 30 Days of German Electricity Production, Carbon Intensity and "Percent Talk" Sources.

For the calculations in this post, I will rely on the 30 day results found on the Electricity Map for Germany for the period from November 15, 2022 to December 14, 2022, during which the average continuous carbon dioxide intensity for Germany was 693 g CO2/kWh.

By contrast, over the same period, the carbon intensity of France, even though its once magnificent nuclear infrastructure is damaged by a dubious decision to defer maintenance and upgrades in order to fund the useless "solar and wind will save us" fantasy, still had a was 137 g CO2/kWh, roughly, in "percent talk" 19.8% that of Germany, or put it another way, German electricity is 505% dirtier than that of France.

Here is a graphic representation of the carbon intensity and sources of primary energy, focusing on the use of filthy and deadly coal, for German electricity generation in the period between November 15, 2022 and December 14, 2022



I will not rely as produce graphics for each energy source as I did in the previously referenced post, but for calculation figures, will rely on the the 30 day period these graphics represent.

It shows that the average continuous power output of German coal plants amounted to 27.8 GW. There are 24 hours in a day so for 30 days, the energy production from coal plants in Germany amounted to 24*30*27.8 = 20,016 GWh. The dangerous fossil fuel natural gas was the second largest producer in that antinuke heaven, Germany, producing 16.6 GW of average continuous power, by a similar calculation to that of coal, producing 11,952 GWh of electricity.

We have people here who still worship the fascist Elon Musk and his slave holding company Tesla, who are always carrying on happily about the industrial installation of Tesla Powerwalls®.

Here are the specifications of Tesla Powerwalls®: Specifications of Powerwalls®.

It is claimed they have a useable capacity of 13.5 kWh after being charged with 14 kWh of electricity, presumably at 25°C, with a putative thermodynamic efficiency - should you choose to believe it - of 96%. The maximum continuous power output is said to be 5 kW. The power requirements to match the combined coal and gas average continuous power of combined German coal and gas over the last 30 days, 44.4 GW would require 8,880,000 million Powerwalls®, to cover each day of Dunkelflaute; for 30 days, given that the wind wasn't blowing that much over that period, 266,400,000 Powerwalls®.

The specifications say that each Powerwall® weighs 114 kg, meaning that 30,369,600,000 kg of Powerwalls® would be required just for Germany.

According to Forbes, 15% of the weight of a Tesla Powerwall is cobalt, mined by Elon's happy Congolese slaves, meaning that the happy Congolese cobalt slaves would be required to mine and isolate 4,555,400 metric tons of cobalt to make Powerwalls® to cover this instance of Dunkleflaute with batteries.

This is 31.63 times as large as the world production of cobalt in 2021 according to the US Geological Survey

I'm sorry!!! I forgot to use "percent talk!" The demand for cobalt to cover month long Dunkleflaute in Germany observed in Nov-Dec 2022 would be 3163% the demand for all the world cobalt supply in 2021...


(I'm pleased to say that I identified Eloon as a fascist before it was popular around here to do so.)

Now, to favor storing energy when so called "renewable energy" remains trivial shows not only contempt for the laws of thermodynamics and a bourgeois fascination with wasting energy - in California they charge batteries while burning dangerous natural gas, meaning they have to burn more dangerous natural gas than they would without batteries, since charging and discharging batteries involves loss of energy - it also shows contempt for human beings.

But, of course, given the moral level I observe in antinukes - their tiresome handwaving in the face of a burning planet - this is no surprise at all.

I really, really, really, really believe that one should not be graduated from high school without being able to state, in simplified form - I'm not asking for understanding Boltzmann's derivations showing the nature of entropy - that storing energy wastes energy.

This is true of the hydrogen scam as well as the battery scam, by the way, storing energy wastes energy. I regard the hydrogen scam as slightly worse than the battery scam - the idea that we should mine the fuck out of the planet in service to stupid reactionary myths because people can't understand basic science - but not by much.

One really doesn't want to believe one hears this shit this late in the game, with the planet in flames, but still one does. It's awful.

By the way, since 2022, France repaired their reactors, and now routinely has a carbon intensity typically on the order of 50-55 grams CO2/kWh (as of this writing 6:29 EST (US) 11/22/24) 53 grams CO2/kWh compared with Germany's 347 grams CO2/kWh.

For the month of October 2024 France's carbon intensity was 23 grams CO2/kWh, compared to coal dependent hellhole Germany's 347 grams CO2/kWh.



The electricity map (accessed 11/22/24)

The contempt for humanity and for the environment shows through every time an advocate of the reactionary "renewable energy" fantasy makes excuses for its inability to address fossil fuels, not that they give a shit about fossil fuels. These advocates are only interested in attacking the last, best, hope of humanity, nuclear energy. They clearly don't give a fuck about fossil fuels.

Have a swell weekend.
