Germany doesn't have too much solar power, some of it just needs to be moved to the evening.
This process has just started but needs to go much further. There are currently 1.4 million electric cars in Germany. If they charged @11KW during the day, they would draw 15.4GW, or roughly the equivalent of 3 Gravelines [1] nuclear power plants running in reverse.
However, most Germans pay the same for electricity throughout the day, so instead they charge when they arrive at home after work and Germany needs to cover 3 Gravelines worth of energy with wind, hydro, coal, and gas instead.
If consumers could charge with solar for 20 cents per kWh during the day or with brown coal for 80 cents per kWh in the evening, many would alter their usage.
Lot of Germany still uses legacy electricity meters. I don't understand why a switch to remote readable meters still hasn't been mandated. This would allow companies to offer market priced electricity with as short as 15 minute price intervals, and would in turn allow consumers to optimise their energy usage to the cheap hours.
I know Nordics do this already, it would be about time for the rest of Europe to follow suit.
According to [1], the installed battery capacity in Germany went from 6.7GWh in 2022 to 12GWH in 2023.
Given the growth and falling cost of battery storage, I expect that more and more solar will stored during the day and consumed in the evening, pushing out coal and gas.
The cost and logistics of containerized batteries hit a tipping point in the last three years and there is no looking back. Because they pay for themselves inside of 24 months.
The press and the agitprop industry goons hired by the fossil fuel companies can gloom and doom all they want but it's all over.
Just a note regarding battery longevity:
LFP batteries like in the Helixx can be charged 0-100% with hardly any impact on battery lifetime [1].
Even NCM or NCA batteries can be charged 1-100%, because the battery management system doesn't actually fully charge or discharge the battery, even if the car shows zero or 100% charge. However, 20-80% or 10-90% charging does increase live time.

Page 6, Figure 3, graphs 'd' shows the number of cycles until the battery can only hold 80% of a charge for LFP, NCM, and NCA batteries. Note that electric cars have a battery management to prevent the most damaging situations in those graphs (too hot/cold, full charge/discharge, too fast, etc.).
Nio offers battery swapping, so the idea is that you do your daily commute with a small 40-80kWh battery and only swap to a gigantic 150kWh battery if you do a road trip.
For other cars this kind of battery size makes not much sense, which is why the vast majority of electric cars sold in the world have a battery sizes between 40 and 80 kWh [1].
Summary:
Samsung includes the losses from the 1024<=>1000 conversion into the system size, making it appear much larger than it actually is.
This also explains why OneUi occupies more space on phones with more storage: 69GB are lost on this conversion on 1TB models, whereas only 9GB are lost on the 128GB model.
If you keep the charge between 20 - 80%, your battery will last for far more cycles than when charging 0 - 100%. So you'll only get 60% of the kWh per cycle, but the battery will do 3-6 times as many cycles.
In fact, the battery management system won't even let you fully charge or discharge the battery for exactly this reason. When it shows 100%, there will still be 1-2 kWh empty and the same for a zero percent charge.
For example, a Toyota Yaris use a tiny (0.7 kWh) lithium ion battery and it gets charged/discharged constantly while breaking/accelerating, but it still last a long time because the charge is kept at about 50%.
Do you have any source that you need a license and insurance to ride with a Waymo car?
Because according to the Waymo One public service rules [1] you need to be 18 or older to use the app and order a Waymo, but they don't mention anything about requiring a license or insurance.
It would also be a weird requirement, since you sit in the back and couldn't control the car even if you wanted to.
Why do you focus on a state that has one of the dirtiest electricity production and one of the lowest rates of EV sales in the US?
If we focus instead on electricity production by source in the USA between 2011 and 2021: Electricity produced...
with oil: 42TWh => 35TW (-16%)
with coal: 1730TWh => 900TWh (-48%)
with gas: 1010TWh => 1580TWh (+55%)
with solar: 2TWh => 164TWh (+8900%)
with wind: 120TWh => 378TWh (+215%)
with nuclear: 790TWh => 780TWh (-2%)
with hydro: 310TWh => 250TWh (-20%)
So not only was 600TWh of dirty coal replaced by cleaner gas, the amount of electricity produced with fossil fuels dropped by more than 200TWh. Meanwhile, electricity production by renewables significantly increased.
Or in other words, if you had bought an EV in 2011 and driven it until now, it would have gotten cleaner every year, which is not going to happen with an ICE.
Source: our world in data, numbers slightly adjusted for readability.
To put it in numbers (actual production per year, not capacity) [1] [2]:
China nuclear 2010: 75 TW/h
China nuclear 2021: 408 TW/h (+333 TW/h)
Worldwide nuclear: 2768 => 2800 (+32 TW/h)
China solar 2010: 0.7 TW/h
China solar 2021: 327 TW/h (+326 TW/h)
Worldwide solar: 34 => 1033 (+999 TW/h)
Luckily, nuclear doesn't really care about solar, since they complement each other perfectly (wind is a different story and it is already much bigger than nuclear).
However, China is a country that is pretty much perfect for nuclear: Little unnecessary regulation, no green party, expertise in nuclear technology, and excellence in constructing large scale construction projects.
So if nuclear is getting overtaken by solar even in China, then I don't see how it will be able to compete in the west against wind and solar.
The annual increase in renewable generation in China is now many times that of the annual increase in nuclear generation. Starting at 2010 leads to an underestimate of the renewables' current velocity advantage over nuclear there.
The article suggested that the west should "compete with the two leaders in global nuclear construction: Russia and China"
to "not only decarbonize, but bring greater prosperity to the world".
So I wanted to show that even if the west emulated China by slashing regulation, outlawing the greens, and dramatically increased our skill at huge construction projects, we still would focus far more on renewables than on nuclear.
(I ignored Russia, because they produce most of their electricity with fossil fuels, and only 18% with nuclear, which is probably not something the west wants to emulate [1]).
