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
Thorium reactor that contribute to the power grid is as much sci-fy as all the technologies you describe to have a working renewable energy grid.
Meanwhile there are whole countries powered from nuclear energy, and switching to thorium makes no difference for the grid itself.
Finally if ecofanatics didn’t shut down or sabotage research on thorium reactors we would be closer from a working tech.
