ficke herum und finde heraus? Oder ist das schon fest verankert?!

Ich bin spät dran. Aber eine wichtige Info: https://sprichwortrekombinator.de/

Business hours as in rural California where restaurants close at 7 pm? But you are right, vacation is pretty great here…

Looks like this: https://en.m.wikipedia.org/wiki/Parthenocissus_tricuspidata

Our family home in Germany is completely covered in it…

Du hast recht. Aber vielleicht hat spahn hier recht und man muss einen Zwischenschritt gehen.

If you are comparing gas to heat pump efficiency it is more like 85-90% vs 350-500% efficiency.

Because in the gas furnace efficiency they only calculate the efficiency of burning gas but muss to include the auxiliary electricity that is needed to run the system.

In a heat pump system everything (running fans etc.) is included in the efficiency calculation. The efficiency itself is depending on the source of the heat pump. In a really harsh climate a ground / geo thermal source might make sense. But usually the average temperature is higher than you might think.

And for the environmental effect: modern gas power plants run at 50-60% efficiency so with a heat pump you are always burning less gas even if the gas plant is less efficient then the gas furnace.

It would be interesting to know what extrem cold means.

Okay lets see. What I meant is: at its time, the Ariane 5 was a great program. Now is a different time. Now we have got SpaceX (and RocketLab etc.) and at the same time the Ariane 6 is already outdated before it is ever launched. At the same time, the Ariane 6 program has run into major delays, so it is not even clear when the first launch will be – probably 2024.

Reusable rocket technology is where it’s at if we as Europeans want to stay relevant in the commercial launch sector.

The Soyuz is not a bad rocket, neither is the Ariane. It is just that technology has advanced quite significantly in the last few years. And rockets are just a (very visible) part of space technology.

I somewhat agree. The only way forward in most areas would be European projects. But we are lacking competent and agile institutions. They got so big and bloated – that for me it looks like they are not able to reform themselves. So first we need good (european) organizations, then we can pour the money over them…

I am a proud European, but do not kid yourself. The United States are light years ahead in space technology. The Ariane program is a complete clusterfuck as of now.

Hoodies are not banned. You are making stuff up.

Yes of course, it is just a piece of clothing. A piece of clothing that women are forced to wear in public in the women’s rights loving state of saudi arabia. It is not about very revealing clothing, you are intentionally missing the point here. It is specifically about this piece of religious clothing.

From what I understand, this affects everyone. All religious symbols are banned from school. I do not know what the rest of your murmuring has to do with the specific topic.

Clearly not racist. Same rules for everyone.

While I agree that it would have been better to phase out coal before nuclear power plants, I also think that those decisions have to be viewed in context and are more nuanced than ‘pretty stupid’.

For example, as other in this thread pointed out, nuclear power plants can be pretty safe to operate IF there is a good culture of safety and protocols in place. Which of course need to be followed and supervised by a strong regulatory body. Two of nuclear power plants in Brunsbüttel and Krümmel were missing this kind of safety culture in the opinion of the regulatory body. They were both operated by Vattenfall. If you lose trust in the operator of such critical infrastructure, then a decision to shut down nuclear power plants has to factor in all the arguments at hand.

Yes, of course, hydrogen is not an energy source (neither are batteries). Sorry if I was not clear about that, I thought it was clear from the context. I was talking about hydrogen and batteries as means of balancing fluctuating output from renewables.

I tend to agree that 44% fossil fuels are still too much, the transition could have been faster and needs to faster in the future. Not a lot of countries have done the successful pivot from fossil energy to renewable energy. The only example that comes to mind is Denmark, where they have great policies (and great wind resources). So I guess everything needs to be viewed in context.

Hmm I think what you mean is that some coal plants have been put into active maintenance. IIRC this was rather a countermeasure in case of absence of gas supplies. They are not part of the regular energy market.

Anyway, I think there is not only one way forward. Countries like France choose to use a big portion of nuclear, Germany does not. And every way has its own challenges. What is important is that energy supply should be independent of oppressor states and moving into a direction of carbon neutrality.

I hope this is a serious question, obviously this depends on your baseline. In 2013 Germany had a 56% share of fossil fuels, 27% share of renewables and 17% share of nuclear power generation. In the current year, the shares are: 59% renewables, 39% fossil fuels and 2% nuclear power generation. So in the last ten years there has been a switch in generation from both nuclear and fossil fuels to renewable generation. Could it have been better in the wake of the looming crisis of both climate and energy? Yes, I think it would have been better to keep some newer nuclear power plants running. But Cpt. Hindsight always has it easier.

In the long run every successful economy will generate its major share of electricity from renewables. Some countries will choose to generate a part with nuclear, others will choose to use a mix of hydrogen, batteries etc. to complement renewables. We will see what works best.

Germany has not build any new coal plants. At least not in the last five years.

Edit: Why are people down voting a factual statement? Go ahead and provide better info if you got it.

While in hindsight not all the decisions of the German energy policies seem right and it would have been better to keep the nuclear power plants operating for a few years, there was never the plan to replace nuclear with coal. All of the nuclear power generation has been replaced by wind and solar power generation. In fact, the plan was to phase out nuclear and replace the remaining coal generation with natural gas power plants. This definitely got more difficult in the time of LNG. The plan in any case is to phase out coal as well and with 56% renewable generation in 2023 Germany is on track to do so.
