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

Sure it can. Battery state, temperature and all is controlled by software..

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 miss 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 extreme cold means.

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.

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.

Wo ist das genau?
