I understand the argument, but afaik the laws that made poeple create cookie banners do not really care whether it’s a cookie or some other identification. Consent has to be granted for any sort of tracking.

However, as far as I understand, at least in some parts of the world, this is only true for 3rd party tracking solutions. So long as people can’t be identified and everything stays with your own host, consent would legally be unnecessary anyway.

I understand the argument, but I see two big reasons for why it’s not valid here. First, e-fuel production and infrastructure needs to be constructed as well. So your calculation needs to consider the entire cost/inefficiency of constructing the entire e-fuel econonomy in the first place.

Second, I can’t imagine existing cars outlasting humanities dependency on fossil fuels for electricity. Cars last what, 20-30 years? I bet humanity is not going to replace all fossil fuel electricity production with green one within the next 100 years. Like I said previously, as long as you burn fossils for electricity, producing e-fuels would only increase carbon emissions, not reduce them.

But yes, when it comes to efficient, it’s best to keep using existing things (barring exceptions where the original thing was too inefficient/dangerous/whatever). That includes not only cars, but also factories, etc. So technically combustion cars should probably still be built for a few decades, until existing factories are too outdated or have reached the end of their life. The same is true for fuel production though - use existing fuel production and don’t invest in e-fuels.

With all of that out of the way, as far as I’m concerned scrapping most of the existing passenger car, regardless of whether it’s combustion or electric, is a good thing. They and their infrastructure take up way too much space, energy and material, not to forget the noise, the smell, the danger, …

Just as preventing waste beats recycling, saving energy beats renewables. “E-fuels” are extremely inefficient and consume four to six times as much electricity as just using a battery would. While Switzerland is producing a lot of electricity from hydropower, they also depend on non-renewable nuclear power sources and its still unsolved dangerous waste problems. As long as countries depend heavily on fossils for electricity, it’s better to sell any potential excess clean electricity (not fossils, not nuclear) to them. Using electricity to generate fuels at a >80% efficiency loss instead of sending it to where it’s needed increases carbon emissions, instead of decreasing them.

If you want to use Discord nowadays you need a valid phone number, that’s it.

No you don’t. I can use it just fine without a phone number added.
