Perhaps they are also running out of fuel. Air Korea stopped flights to Russia as well citing lack of fuel.

Seems the sanctions are really hitting hard.

Europe has an integrated grid. The purpose of this grid is to balance fluctuations. NordLink (https://www.tennet.eu/our-grid/international-connections/nor... ) was explicitly build to access the more than 100 TWh of available pumped water storage in Norway to store wind energy. And I guess Norway is making some money from it. Denmark has an even higher share of wind energy than Germany (70% last week). The Netherlands got 30% of its energy from wind last week, Austria 26%, Poland 25%. France uses German electricity when it is cold in winter and resistance heating is using more energy than they can produce or if they have to shut down some nuclear plants because of security issues (https://www.express.co.uk/news/science/1549986/macron-france... ). They are all pulling the same trick.

Again: Balancing is the purpose of the grid and not "shitting on neighboring countries".

Germany needs to replace gas heatings with heat pumps and gas usage in industry with hydrogen to reduce the dependency on Russian gas.

The problem is not a lack of electric energy (this year also 12 coal plants will be shut down, while a lot of renewable energy is being installed). Reopening the nuclear plants will not help.

France uses 40.7 billion cubic meters of gas (0.6 per capita), while Germany uses 86.5 (1.03 per capita). Given that France has a warmer climate the difference is not all that big. France does not survive on nuclear power alone.

So the dependency will be reduced on both sides.

"In addition to defects in the fog light and the low beam, the Model S at the HU mainly has problems with the wishbones. " so not a lot of information in there either.

"The CJEU ruled that the Privacy Shield does not provide adequate protection, and invalidated the agreement. The court also ruled that European data protection authorities must stop transfers of personal data made under the standard contractual clauses by companies, like Facebook, subject to overbroad surveillance. This decision has significant implications for U.S. Companies and for the U.S. Congress because it calls into question the adequacy of privacy protection in the United States."

While I agree that fighting climate change should be a top priority and probably no country is currently doing enough to get to net-zero CO2 fast enough, I don't think the comparisons to a crisis year like 2020 are all that helpful.

Seeing the problems is important, but seeing successes is important as well in order to prevent everyone from loosing hope.

It is hard to get any unbiased information on cost, but to me it seems that even today renewable + storage is cheaper than building nuclear (https://en.wikipedia.org/wiki/Levelized_cost_of_energy#/medi... ).

So there is neither the political option nor an economic case for nuclear. Other countries will be subsidizing nuclear and make different decisions. It will be interesting to watch, if France will be able to build nuclear reactors in time and on budget and if Germany will be able to keep the grid stable. Both approaches carry some risks.

Coal: Bad, yes. This is being phased out: https://www.bmu.de/en/topics/climate-adaptation/climate-prot...

Gas: Mostly used for heating in Germany. Should be replaced with heatpumps/better insulation. Bad for heating, but since gas power plants are cheap, new gas plants will be used to generate electricity during the "Dunkelflaute" (no wind, no sun) until better solutions are available. So good for emergencies since plants are cheap and gas can be stored.

Solar: Good, many people have it in their back yards and I'm not aware of any protests.

Wind: Good, but most wind is in the north and Bavaria is blocking SuedLink, since the North will profit from it: https://www.deutschlandfunk.de/kampf-gegen-stromtrassen-waru... So currently adding additional wind power in the north does not make a lot of sense, if the energy cannot be used. This is why a lot off offshore wind power is being delayed.

The new government is planning for 680-750TWh (80% renewable) of electricity in 2030 compared to 560TWh in 2020 (https://dynamic.faz.net/download/2021/Koalitionsvertrag2021-... ). So they are planning for electric cars as well. Electric cars are also interesting, because you can charge the cars based on prices / grid load thus making the grid more stable.

There are projects like NordLink (https://www.tennet.eu/our-grid/international-connections/nor... ) that use pumped storage in Norway for storing energy (capacity: 87TWh https://energifaktanorge.no/en/norsk-energiforsyning/kraftpr... ).

Also the high electricity prices in winter are aften caused by France, since a lot of electric heating is used there (https://www.bloomberg.com/news/articles/2021-12-01/france-fa... ).

Interesting times indeed, but I guess the new government will be more forward looking than the previous one.

A few hundred percent differences in spot prices is ok, since only a small amount of electricity is traded there. And these differences will make battery storage viable.

2.) Got a velomobile (https://www.velomobileworld.com/product/milan-gt/ ). This was actually not supposed to be a hobby but a way to get to work while not producing too much C02. 50km each way were to far for a normal bicycle, an ebike is still to slow. With the velomobile I could average 40km/h and stay fit at the same time -- until Covid/Home Office came along. This year I took some time off and cycled 11000km in 3 month. From Northern Germany to the Black Sea, to the Atlantic Coast and back to Germany again. This took some time and effort ;) But with cycling you can spend as much time/effort as you please. You can tour alone or in groups... many options.

Yes, because this is not the case.

https://www.bussgeldkatalog.de/geschwindigkeitsbegrenzung-au...

I didn't want to imply this. I was just talking about the task of finding the speed limit. Getting from there to a reasonable speed to drive at is a different issue and much more complicated, yes ;)

"Das Ende einer streckenbezogenen Geschwindigkeitsbeschränkung oder eines Überholverbots ist nicht gekennzeichnet, wenn das Verbot nur für eine kurze Strecke gilt und auf einem Zusatzzeichen die Länge des Verbots angegeben ist. Es ist auch nicht gekennzeichnet, wenn das Verbotszeichen zusammen mit einem Gefahrzeichen angebracht ist und sich aus der Örtlichkeit zweifelsfrei ergibt, von wo an die angezeigte Gefahr nicht mehr besteht. Sonst ist es gekennzeichnet durch die Zeichen 278 bis 282."

The translation of this is: If a speed limit is combined with another sign indicating a reason for the speed limit (e.g. construction work, dangerous curve, train crossing...) the speed limit automatically ends without any additional sign.

So basically the AI has to understand why the speed limit is there and decide when it has passed the dangerous part of the road.

When starting to drive the car has to recognize if it is inside the city (50km/h or 30km/h limit depending on location), outside the city (100 km/h) or on the autobahn (no limit). This is simply impossible without having a map. You could save the state from the previous drive. But what happens if the car gets towed from the autobahn into a city. Will drive through the city without any speed limit?

I don't think this is simple at all.

If you can legally rely on the speed limits in the maps, this should be much easier to do.

Recognizing speed limits seems to be a technical solution to an organizational problem.

Number of instructions is probably not a good metric. Without any loops/jumps you might have a lot of instructions, but a very low complexity.

An endless loop executes a lot of instructions, but does not have to be complex.

This one is actually quite practical and fun to cycle. Also it starts sailing in strong cross winds.

"In several speeches by Joseph Goebbels from the first half of 1939, "Lugenpresse" is used to characterize the media abroad, especially the future war opponents of the USA, France and Great Britain. At this point in time the German domestic press was "synchronized" (controlled), a domestic press that the National Socialists referred to as the Lugenpresse no longer existed."

Perhaps learn a bit of history to understand how this word was used and why people think you are a "alt-right twerp" if you use it. The press has some issues. But believing the propaganda of one party or random crap comments on the internet instead of the press is certainly no improvement.

There is no news source without a bias. The only way to learn about the world is to understand the bias, learn from different sources (even sources opposing your own view) and combine this into your own world view.

Unfortunatly this project was cancelled since Germany taxes electricity from batteries two times: Once when charging the battery and once when discharging it (since it is then seen as "producing" electricity).

https://ehss.energy.gov/SESA/Files/corporatesafety/safety_bu... On April 20, 2005, a camera inspection of a feed clarification cell at THORP revealed that 83,000 liters of dissolver solution had leaked from a broken pipe (Figure 1) into the cell sump. The highly radioactive dissolver solution, consisting of approximately 19 metric tons of uranium, plutonium and fission products dissolved in nitric acid, was entirely contained within the stainless steel-lined cell. No personnel were injured as a result of this incident. However, the cleanup costs for this event are expected to exceed $500 million, and the THORP facility faces a lengthy shutdown (possibly even permanent closure).

France: https://www.scientificamerican.com/article/is-reprocessing-t... Reprocessing also results in radioactive liquid waste: the French reprocessing plant in La Hague discharges 100 million liters of liquid waste (pdf) into the English Channel each year. "They have polluted the ocean all the way to the Arctic," Makhijani says. "Eleven western European countries have asked them to stop reprocessing."

Germany: https://www.nwtrb.gov/docs/default-source/meetings/2018/marc... Since 1991* increasing inflow of brine from the Southern flank Since 1994* reports on contaminated brines (3H, 137Cs)

* From a security point of view: With the sidecar approach a simple port misconfiguration can remove the authentication. Is this a good idea?

* The egress container cannot propagate the original token used while calling the API. So the authentication is at this point only an authentication of the first backend service being allowed to call the second backend service (with a new token). This makes authorization checks for the original caller (or any operation relying on the data from the token) in the second service impossible. Or am I missing something?

It is probably a good idea to do one or more test drives first, so you know what you are getting into and what is important to you.

You are right, that there needs to be some sort of mechanism to stabilize the grid in case renewables are not available. But nuclear energy is not an option for this since it takes days to start a reactor. So what are the options?

* Gas turbines (in the short run, known technologie, fast start-up times, but still creating CO2 even if less than coal)

* Batteries (e.g. https://www.ewe-gasspeicher.de/en/home/b4p )

* Smart Grid (electric cars for example are often flexible in their charging times).

* Pump storage

e.g. "Asse" was a salt mine to test storing nuclear waste. It was supposed to last for 20.000 years, but only lasted 20 and its not possible to retrieve the waste stored in there (and environmentalists warned that this would happen). So will you trust these people to get the decision right the next time?

https://translate.google.com/translate?sl=auto&tl=en&u=http%...

Gorleben (another salt mine) was chosen for nuclear waste storage partly to piss of the former GDR since it is right next to the border. Neither a very good reason.

Compared to the US Germany just does not have any uninhabitated areas, where you can store nuclear waste.

France is not free from problems either: https://www.reuters.com/article/europe-power-supply/germany-...

A load balancer / forwarding web server might filter the t3 requests, but I wouldn't want to rely on this. Also t3 can be tunneled over http (although this is not enabled in the default configuration).
