Europe is back in the coal business, thanks to the US taking out their gas pipeline from Russia, and India is also big-time into coal. The US is about the only major country that has killed off its coal industry, but then we’re a Fascist State so our Congress doesn’t even get to vote on it.
We could be mining our own coal and exporting the excess to other countries and use it to increase our standing. We could do the same for oil. For that matter we could do the same with the so-called “rare earths”, many of which we have here but refuse to mine.
