It takes time to come to the realization that a lot of what we do is inefficient because that's just what people are used to doing. Some towns survive solely due to coal mining, and they see it as an existential threat if it were shut down. Nuclear power also takes very knowledgeable individuals, years of planning, and many resources to get started. Coal is cheap, dirty, and primitive.

Use hydrogen for that (using coal creates 1.5 tons CO² per ton steel). Green steel needs no phosphor and sulfur too, making it stronger.

Hydrogen isn't cheap, though.

[-] MonkderVierte@lemmy.zip 5 points 1 week ago

Gets cheaper though.

It is if you have a nuclear power plant

[-] rumschlumpel@feddit.org 7 points 1 week ago

Ah yes, the famously cheap nuclear power plant.

How expensive is it per MWh compared with coal if you account for removing the CO2 from the atmosphere?

[-] rumschlumpel@feddit.org 2 points 1 week ago* (last edited 1 week ago)

Most countries don't and won't do that, though. Coal is only expensive when a society agrees to stop externalizing the costs, and that only works if either most major countries are doing it or when they severely restrict trade with countries that keep externalizing the costs.

and that is unfortunately game theory problem without working solution, which is why we are fucked :(
