Why has the world started to mine coal again? (lemmy.ml)

With climate change looming, it seems so completely backwards to go back to using it again.

Is it coal miners pushing to keep their jobs? Fear of nuclear power? Is purely politically motivated, or are there genuinely people who believe coal is clean?

Edit, I will admit I was ignorant to the usage of coal nowadays.

Now I'm more depressed than when I posted this

More than likely it's a cost issue, coal is artificially cheap thanks to several countries subsidizing the coal industry like Germany, USA and Australia.

There's also I guess the practical question of how much plant fiber per ton of metallurgical coal is needed, i.e. how land would be dedicated towards 'producing plant fiber' for the steel industry.

    Coconut husks are free with the coconuts, which is why I mentioned them. Without explicitly breaking out my highschool chemistry, I'm guessing you get about a third the mass of carbon from cellulose.

    If it's a whole 7% of the coal mined, though, that is a pretty significant amount. I assume we'll have to find less agricultural ways of fixing CO2 at some point, because it is kind of a shame to use prime agricultural land to make industrial feedstock. NASA already has a device that can turn it into CO electrically, I guess.
