Love it, thanks!

Great work! Do you have some more pics or maybe even a video?

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.

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.
