China is leading in both, but I'm more interested in local BESS and other storage deployments locally in northern Europe. I think for example Spain started getting more heavily involved only after their massive blackout. According to those links there is a very large overcapacity in battery production, but I don't see it reflected here. I'm sure it will happen at some point though.
To answer ajross: I'm quite sure that the shutdown of Ringhals and Barsebäck in southern Sweden has had a much greater impact on their and likely southern Norway's prices as well than building for example 10 times the equivalent solar capacity in Spain. It is not even about losses, but just the grid capacity. Theoretically the prices in Nord Pool (from southern France and western Ireland to northern Norway and eastern Baltics) should be equal. As pointed out, in practice they vary wildly. And in principle it can get even worse. It would not be too unrealistic to have negative prices in northern Norway and rolling blackouts in southern Sweden at the same time. I'll leave it as an exercise to the reader how the latter can even happen when Sweden has enough capacity to meet its power demand at that time.
For example a decade ago electricity prices in Nord Pool were relatively stable (and reasonable/lowish). Now it is quite common to either have 0 or even negative prices during summer and artificially set maximums in the autumn/winter. IIRC, the rules were that if the price hit 60% of the maximum, it had to be raised by 1000 €/MWh. It got to 4000 €/MWh (which is 4 € or $4.7/kWh) in 2022 and was supposed to be raised by another 1000, but it was decided not to do it, so I think it stands there right now. But in any case, this is a ridiculous price. As are the negative ones.
It's about nobody making any money, so there will be no incentive to continue building solar.

I can also say, that my hypothetical landlord has nothing to do with the place I have lived in for 10 years. So therefore they do not "own" it.

If this is wrong, please remove it from Wikipedia too, or add an explanation why this plan failed.
Also, if this is wrong, we cannot trust what anyone from Mozilla has to say, including you since they can say one thing and do another.
Also, if this is wrong, why are there consolidated financial statements of "MOZILLA FOUNDATION AND SUBSIDIARIES (Mozilla)" https://assets.mozilla.net/annualreport/2021/mozilla-fdn-202... According to the report, Mozilla foundation (and its subsidiaries) had a revenue of $600M in 2021. If the foundation has no control over the corporation, how can it include the revenue of the corp in its financial report? Is something fraudulent going on in Mozilla?

"a = a" just means assign the value of local variable "a" to a local variable "a", so the error makes sense.
I have not designed a motherboard, but plenty of smaller digital IC-based schematics and PCBs and in my experience the most problematic part has been either erroneous or lack of proper documentation or bugs in ICs which there are plenty of.
What I recommend you to do is to compare the schematics of, for example, Thinkpad T420 and Keithley 2001 both of which should be available with a search. What you will find is that the former is a collection of specialized chips (including one for battery charging) with mostly datasheet reference design based implementations + bunch of mosfets for enabling/disabling/routing signals, whereas the latter has almost none of that and plenty of analog "cleverness" and "raw" digital design, let alone the power input, which in my opinion was totally overdesigned. Or take any oscilloscope, where you need to design not only a computer but also an analog front-end + high frequency signal processing, not only routing. And I'm not even going into the actual RF board designs which you are probably well aware of is more physics than electronics.
Again I am not saying that it is easy for any guy on the street, but "relatively easy" to understand what is going on on the motherboard as opposed to the actual complex stuff. So if you see a common fault among many motherboards you can probably conclude that that specific area of the design was bad and criticize that. Whether the criticism is valid might be another question, but I would not automatically dismiss it.
Edit: I will put designing a motherboard on my todo list.
I am not saying it is trivial or that Rossmann could do it with his knowledge (no, he could not) or that anyone could do it. I just claimed that in the grand scheme of things it is not "highly complex" (as opposed to pretty much anything analog, or proper RF, or getting the actual implementation inside the chips correct).
The design of a modern motherboard is far from complex since all the complexity has pretty much been hidden inside the black boxes of highly integrated circuits. You as a designer do not in general need to concern yourself with the implementation details and just need to understand the interfaces, similar to, for example, using python's numpy as opposed to writing BLAS or LAPACK from scratch.
This is just a blatant lie and in fact complete opposite of what he is saying:
The Finland events are obviously Jokela and Kauhajoki.
